Cisco IOS XR Software running on the Cisco XR 12000 Series Router provides the following features and benefits:
IP and Routing—This supports a wide range of IPv4 and IPv6 services and routing protocols such as Border Gateway Protocol (BGP), Routing Information Protocol (RIPv2), Intermediate System-to-Intermediate System (IS-IS), Open Shortest Path First (OSPF), IP Multicast, Routing Policy Language (RPL), , Hot Standby Router Protocol (HSRP), and Virtual Router Redundancy Protocol (VRRP) features.
BGP Prefix Independent Convergence—This provides the ability to converge BGP routes within sub seconds instead of multiple seconds. The Forwarding Information Base (FIB) is updated, independent of a prefix, to converge multiple 100K BGP routes with the occurrence of a single failure. This convergence is applicable to both core and edge failures and with or without MPLS. This fast convergence innovation is unique to Cisco IOS XR Software.
Multiprotocol Label Switching (MPLS)—This supports MPLS protocols, including Traffic Engineering (TE), Resource Reservation Protocol (RSVP), Label Distribution Protocol (LDP), Virtual Private LAN Service (VPLS), and Layer 3 Virtual Private Network (L3VPN).
Multicast— This provides comprehensive IP Multicast software including Source Specific Multicast (SSM) and Protocol Independent Multicast (PIM) in Sparse Mode only.
Quality of Service (QoS)—This supports QoS mechanisms including policing, marking, queuing, random and hard traffic dropping, and shaping. Additionally, Cisco IOS XR Software also supports modular QoS command-line interface (MQC). MQC is used to configure QoS features.
Manageability—This provides industry-standard management interfaces including modular command-line interface (CLI), Simple Network Management Protocol (SNMP), and native Extensible Markup Language (XML) interfaces. Includes a comprehensive set of Syslog messages.
Security—This provides comprehensive network security features including access control lists (ACLs); routing authentications; Authentication, Authorization, and Accounting (AAA)/Terminal Access Controller Access Control System (TACACS+), Secure Shell (SSH), Management Plane Protection (MPP) for management plane security, and Simple Network Management Protocol version3 (SNMPv3). Control plane protections integrated into line card Application-Specific Integrated Circuits (ASICs) include Generalized TTL Security Mechanism (GTSM), RFC 3682, and Dynamic Control Plane Protection (DCPP).
Craft Works Interface (CWI)—CWI is a client-side application used to configure and manage Cisco routers. Management and configuration features include fault, configuration, security, and inventory, with an emphasis on speed and efficiency. The CWI provides a context-sensitive graphical representation of the objects in a Cisco router, simplifying the process of configuring and managing the router. The CWI allows you to log in to multiple routers and perform management tasks.
Availability—This supports rich availability features such as fault containment, fault tolerance, fast switchover, link aggregation, nonstop routing for ISIS, LDP, BGP, OSPF, and nonstop forwarding (NSF).
Multicast service delivery in SP NGN—MVPNv4 support carries multicast traffic over an ISP MPLS core network.
IPv6 Provider Edge Router support for IPv6 applications—This delivers IPv6 traffic over an IPv4/MPLS core with IPv6 provider edge router (6PE) support.
IPv6 VPN over MPLS (6VPE) support—This delivers IPv6 VPN over MPLS (IPv6) VPN traffic over an IPv4 or MPLS core with 6VPE support.
6VPE over L2TPv3 support—This delivers IPv6 VPN traffic over L2TPv3 core with 6VPE support. This feature is also available on Cisco IOS Software.
Enhanced core competencies:
L2TPv3 Tunneling Mechanism—Service Providers who do not use MPLS in the core, but want to offer VPN services can use the L2TPv3 tunneling mechanism. This feature support includes IPv4 (VPNv4) and IPv6 (6VPE) VPN services using L2TPv3 encapsulation. This L2TPv3 packet is encapsulated in an IPv4 delivery header and is carried across an IPv4 backbone. VPN prefixes are advertised with BGP labels and resolved over L2TPv3 tunnels. This feature is supported only on the Cisco XR 12000 Series Router.

Line cards (LCs)
For Engine 3 line card:
Maintenance Bus (MBUS) Agent Software-RAM version 4.7, ROM version 4.7
ROM Monitor version 19.0
Fabric Downloader - RAM version 10.1, ROM version 10.1 (The ROM version will be the same as the RAM version if upgraded.)
For Engine 5 line card:
Router processors (RPs)
For Performance Route Processor 2 (PRP-2):
For Performance Route Processor 3 (PRP-3):
Minimum Firmware Requirement
After completing an RMA the newly-received linecard may not have appropriate IOS XR firmware installed.
Depending on the type of firmware that needs upgrading the symptoms can vary as follows:
ROMMON needs updating the linecard will not boot up
MBUS needs updating the line card may fail to boot or keeps reloading
Fabric Loader needs updating the line card will take long time to boot
FPD needs updating the line card experiences packet corruption / drop
Note
The FPD PIE has to be installed in order to upgrade to the latest FPD image. Refer to the Upgrading FPD on Cisco IOS XR Software chapter of the Cisco IOS XR System Management Command Reference for the Cisco XR 12000 Router online.
RMA Card Firmware Upgrade Procedure
To upgrade the fabric-downloader, ROMMON, Mbus, and current field-programmable device (FPD) image package on a single RMA linecard or on all modules installed in a router, use the upgrade all command in the admin mode.
upgrade all location {node-id | all} [force]
Where location node-id specifies that all ROM images will be upgraded on the physical location of the line card received through RMA defined by the node-id argument. The node-id argument is entered in the rack/slot/module notation.
The upgrade all location all command upgrades all ROM images on all line cards (LCs) that are installed in the router.
For an RMA linecard firmware upgrade you'll want to use the upgrade all location {node-id} command
The optional force parameter skips the version check and forces an upgrade.
The list of minimum supported firmware versions is available online in this matrix which contains links to PDF copies of the IOS XR Firmware Upgrade Guides which are available online here :
http://www.cisco.com/web/Cisco_IOS_XR_Software/index.html
Refer to the Hardware Redundancy and Node Administration Commands on Cisco IOS XR Software chapter of the Cisco IOS XR System Management Command Reference for the Cisco XR 12000 Router for the upgrade all command syntaxhttp://www.cisco.com/en/US/docs/routers/xr12000/software/xr12k_r4.0/system_management/command/reference/b_yr40xr12k_chapter_0111.html.
Requirement of Cisco IOS Image Level and Boot Helper Version for Migration
If you are migrating from Cisco IOS to Cisco IOS XR Software on the Cisco XR 12000 Series Router, you must have the following minimum Cisco IOS image level and Boothelper version to support Release :
If you have an earlier version of this system, you must upgrade to the minimum supported level before performing a migration. Otherwise, your migration fails. For more information, see Migrating from Cisco IOS to Cisco IOS XR Software on the Cisco XR 12000 Series Router document.
Determining Your Software Version
ProcedureTo determine the version of Cisco IOS XR Software running on your router, log in to the router and enter the show version command:
PPPoE Session Limit and Throttle
PPPoE Session Limit
The PPPoE Session Limit support limits the number of PPPoE sessions that can be created on a BNG router. As a result, it reduces excessive memory usage by the BNG router for virtual access.
This offers additional configuration flexibility on the BNG router by limiting the number of PPPoE sessions for each:
Line card
Parent interface
Peer MAC address
Peer MAC address under individual access interface
Circuit-ID
Remote-ID
Combination of Circuit-ID and Remote ID
Access interface using the same Inner VLAN tag
Access interface using the same Outer VLAN tag.
Access interface using the same Inner and Outer VLAN tags
The PPPoE Session Limit support also limits the number of Inter Working Function (IWF) sessions for each peer MAC address and for each peer MAC address under individual access interface.
PPPoE Session Throttle
The PPPoE Session Throttle support on BNG limits the number of PPPoE session requests coming to BNG within a specified period of time. This, in turn, ensures that the session establishment of other client requests coming to the BNG server is not impacted.
This offers configuration flexibility in the BNG router by throttling the number of session requests based on one of these:
Peer MAC address
Peer MAC address under individual access interface
Circuit-ID
Remote-ID
A combination of Circuit-ID and Remote ID
Inner VLAN tag under individual access interface
Outer VLAN tag under individual access interface
Inner and Outer VLAN tag under individual access interface
The PPPoE session throttle support also throttles the number of Inter Working Function (IWF) session requests for each peer MAC address under an individual access interface.
For more information about the PPPoE Session Limit and Throttle, see the Establishing Subscriber Sessions chapter in the Cisco ASR 9000 Series Aggregation Services Router Broadband Network Gateway Configuration Guide. For complete command reference of the PPPoE commands, see the PPPoE Commands chapter in the Cisco ASR 9000 Series Aggregation Services Router Broadband Network Gateway Command Reference.
Software Features Introduced in Cisco IOS XR Software Release 4.3.0
BGP-RIB Feedback Mechanism for Update Generation
The Border Gateway Protocol-Routing Information Base (BGP-RIB) feedback mechanism for update generation feature avoids premature route advertisements and subsequent packet loss in a network. This mechanism ensures that routes are installed locally, before they are advertised to a neighbor.
BGP waits for feedback from RIB indicating that the routes that BGP installed in RIB are installed in forwarding information base (FIB) before BGP sends out updates to the neighbors. RIB uses the the BCDL feedback mechanism to determine which version of the routes have been consumed by FIB, and updates the BGP with that version. BGP will send out updates of only those routes that have versions up to the version that FIB has installed. This selective update ensures that BGP does not send out premature updates resulting in attracting traffic even before the data plane is programmed after router reload, LC OIR, or flap of a link where an alternate path is made available.
To configure BGP to wait for feedback from RIB indicating that the routes that BGP installed in RIB are installed in FIB, before BGP sends out updates to neighbors, use the update wait-install command in router address-family IPv4 or router address-family VPNv4 configuration mode. The show bgp, show bgp neighbors, and show bgp process performance-statistics commands display the information from update wait-install configuration.
For more information on the update wait-install and show bgp commands, see the BGP Commands chapter in the Cisco IOS XR Routing Command Reference for the Cisco XR 12000 Series Router.
EIGRP Wide Metric Computation
The Cisco IOS XR Enhanced Interior Gateway Routing Protocol (EIGRP) implementation is enhanced to perform wide metric computation. This enhancement is to support high bandwidth interfaces.
A new EIGRP command is added and existing EIGRP commands are enhanced to support wide metric computation feature.
metric rib-scale—This command was introduced.
metric—The picoseconds keyword was added.
metric weights—Support was added for the k6 constant.
show eigrp interfaces—The command output was modified to display relevant wide metric information.
show eigrp neighbors —The command output was modified to display relevant wide metric information.
show eigrp topology—The command output was modified to display relevant wide metric information.
show protocols—The command output was modified to display relevant wide metric information.
For more complete command reference information of these commands, see the EIGRP Commands chapter in the Cisco IOS XR Routing Command Reference for the Cisco XR 12000 Series Router.
Note
If there is a combination of IOS and IOS-XR PE devices in the network, then the EIGRP wide metric must be disabled in IOS-XR PE device. This is because the method of calculating metrics in L3VPN design between IOS and IOS-XR.OSPFv3 Timers Link-state Advertisements and Shortest Path First Throttle Default Values Update
The Open Shortest Path First version 3 (OSPFv3) timers link-state advertisements (LSAs) and shortest path first (SPF) throttle default values are updated to:
timers throttle lsa all—start-interval: 50 milliseconds and hold-interval: 200 milliseconds
timers throttle spf —spf-start: 50 milliseconds, spf-hold: 200 milliseconds, spf-max-wait: 5000 milliseconds
For complete command reference of the timers throttle lsa all and timers throttle spf commands, see the OSPFv3 Commands chapter in the Cisco IOS XR Routing Command Reference for the Cisco XR 12000 Series Router.
Route Convergence Monitoring and Diagnostics OSPF Type 3/5/7 Link-state Advertisements Monitoring
The Route Convergence Monitoring and Diagnostics (RCMD) OSPF type 3/5/7 link-state advertisements (LSA) monitoring feature flags and differentiates the LSAs during the monitoring of LSAs. A change in route for type 3/5/7 LSAs has to be monitored. During the route calculation, if the route source appears to be type 3/5/7 LSAs and the route change is an add or delete action, then those prefixes have to be monitored. RCMD monitors all deletion of available paths (a purge operation) and addition of the first path (a restoration operation) for all type 3/5/7 LSAs. The OSPF type 3/5/7 LSAs are monitored and reported on a individual prefix basis. However, a modify operation that involves a change in paths not affecting reachability as a whole, is not monitored. Although all prefixes are logged for reporting, the convergence tracking is rate-limited for the first 10 prefixes that are affected in an SPF run.
The RCMD OSPF type 3/5/7 LSA monitoring is enabled by configuring the track-external-routes and track-summary-routes under Router OSPF monitor-convergence configuration mode.
Route Convergence Monitoring and Diagnostics Prefix Monitoring
The Route Convergence Monitoring and Diagnostics (RCMD) prefix monitoring feature enables convergence monitoring for specific individual prefixes in Open Shortest Path First (OSPF) and Intermediate System-to-Intermediate System (IS-IS) Interior Gateway Protocols (IGP). In IGP, when the route information is created, the prefix is verified against the configured prefix-list. If the prefix is found to be monitored, it is marked for monitoring and information about each prefix change event is captured. The RCMD prefix monitoring individually monitors specific prefixes on each RCMD enabled router in the network. A maximum of 10 prefixes can be monitored. Individual prefix monitoring compliments the probes enabled at customer network edges to monitor connectivity and availability of specific service end-points.
The RCMD prefix monitoring for IS-IS prefixes is enabled by configuring the prefix-list command under Router IS-IS monitor-convergence configuration mode. The RCMD prefix monitoring for OSPF prefixes is enabled by configuring the prefix-list command under Router OSPF monitor-convergence configuration mode.
VRF-lite Support for OSPFv2
VRF-lite capability is enabled for OSPF version 2 (OSPFv2). VRF-lite is the virtual routing and forwarding (VRF) deployment without the BGP/MPLS based backbone. In VRF-lite, individual provider edge (PE) routers are directly connected using VRF interfaces. To enable VRF-lite in OSPFv2, configure the capability vrf-lite command in VRF configuration mode. When VRF-lite is configured, the DN bit processing and the automatic Area Border Router (ABR) status setting are disabled.
For complete command reference information of the capability-vrf command, see the OSPFv2 Commands chapter in the Cisco IOS XR Routing Command Reference for the Cisco XR 12000 Series Router
Flow-Aware Transport Pseudowire
Routers typically balance traffic load based on the lowermost label in the label stack, which is the same label for all flows on a given pseudowire. This may lead to asymmetric load balancing. The flow, in this context, refers to a sequence of packets that have the same source and destination. The packets are transported from a source provider edge (PE) to a destination PE.
Flow-Aware Transport Pseudowire (FAT PW) provide the capability of identifying individual flows within pseudowire and provide routers the ability to use these flows to balance traffic load. FAT PWs are used to balance traffic load in the core when equal cost multipaths (ECMP) are used. A flow label is created based on indivisible packet flows entering a pseudowire; it is inserted as the lower most label in the packet. Routers can use the flow label for balancing load; this provides better traffic distribution across ECMP paths or link-bundled paths in the core.
For more information on FAT PW, see the Implementing Virtual Private LAN Services module in the Cisco IOS XR Virtual Private Network Configuration Guide for the Cisco XR 12000 Series.
Pseudowire Grouping
When pseudowires (PW) are established, each PW is assigned a group ID that is common for all PWs that are created from the same physical port. Therefore, when the physical port becomes non-functional or is deleted, L2VPN sends a single message to advertise the status change of all PWs belonging to the group. A single L2VPN signal thus avoids a lot of processing and the resulting loss in response.
For more information on configuring pseudowire groups, see the Implementing Point to Point Layer 2 Services module in the Cisco IOS XR Virtual Private Network Configuration Guide for the Cisco XR 12000 Series Router . For more information on commands to configure pseudowire groups, see the Cisco IOS XR Virtual Private Network Command Reference for the Cisco XR 12000 Series Router.
L2VPN Nonstop Routing
The L2VPN Nonstop Routing (NSR) feature avoids label distribution path (LDP) sessions from flapping on events such as process failures (crash) and route processor failover (RPFO). If you have enabled NSR using NSR process failure switchover, NSR on process failure (crash) is supported by performing RPFO.
NSR enables the router (where failure has occurred) to maintain the control plane states without a graceful restart (GR). NSR, by definition, does not require any protocol extension and typically uses Stateful Switch Over (SSO) to maintain its control plane states.
For more information on configuring L2VPN NSR, see the Implementing Point to Point Layer 2 Services module in the Cisco IOS XR Virtual Private Network Configuration Guide for the Cisco XR 12000 Series Router .
IPv6 Support for IP SLA ICMP Echo Operation
IP Service Level Agreements (SLAs) Internet Control Message Protocol (ICMP) Echo operation is used to monitor the end-to-end response time between a Cisco router and devices using IP. ICMP Echo is useful for troubleshooting network connectivity issues.
For more information about IPv6 Support for IP SLA ICMP Echo operation feature, see the Implementing Host Services and Applications module in the Cisco IOS XR IP Addresses and Services Configuration Guide for the Cisco XR 12000 Series Router.
For complete command reference of the Host Services and Applications commands, see the Host Services and Applications Commandschapter in the Cisco IOS XR IP Addresses and Services Command Reference for the Cisco XR 12000 Series Router
Multiple Group Optimization for Virtual Router Redundancy Protocol
Multiple Group Optimization for Virtual Router Redundancy Protocol (VRRP) provides a solution for reducing control traffic in a deployment consisting of many subinterfaces. By running the VRRP control traffic for just one session, the control traffic is reduced for the subinterfaces with identical redundancy requirements. All other sessions are slaves of this primary session, and inherit their states from it.
For more information about Multiple Group Optimization for VRRP feature, see the Implementing VRRP module in the Cisco IOS XR IP Addresses and Services Configuration Guide for the Cisco XR 12000 Series Router.
For complete command reference of the VRRP commands, see the VRRP Commandschapter in the Cisco IOS XR IP Addresses and Services Command Reference for the Cisco XR 12000 Series Router
GMPLS UNI
The Generalized Multiprotocol Label Switching (GMPLS) User Network Interface (UNI) creates a circuit connection between two clients (UNI-C) of an optical network. This connection is achieved by signaling exchanges between UNI Client (UNI-C) and UNI Network (UNI-N) nodes, where UNI-C nodes are router nodes and UNI-N nodes are optical nodes.
For more information about implementing GMPLS UNI feature, see the Cisco IOS XR MPLS Configuration Guide for the Cisco XR 12000 Series Router and Cisco IOS XR MPLS Command Reference for the Cisco XR 12000 Series Router.
1-Port 10-Gigabit Ethernet SPA
There are two types of 1-Port 10-Gigabit Ethernet SPA:
SPA-1X10GE-L-V2—Supports 10-Gigabit Ethernet LAN physical layer device (PHY) mode of operation at an optical interface bit rate of 10.3125 Gbps.
SPA-1X10GE-WL-V2—Supports both 10-Gigabit Ethernet LAN PHY mode of operation (at 10.3125 Gbps) and the 10-Gigabit Ethernet WAN PHY mode of operation (at 9.95328 Gbps).
For more information about 1-Port 10-Gigabit Ethernet SPA, see the Cisco XR 12000 Series Router SIP and SPA Hardware Installation Guide.
SPRAS for Link Bundling
When QoS policies are applied on bundles, they helps reduce the traffic loss time during the addition and/ or removal of bundle members. Traffic loss can be minimized upto 50 percent.
NAT64 Service Module Daughter Card
The Carrier Grade Network Address Translation (Stateful NAT64) services and features are now deployed on Cisco XR 12000 Series Routers using the Service Module Daughter Card (SMDC).
The SMDC plugs directly into a Performance Route Processor (PRP-3) board and enables additional features and services that cannot be enabled with the existing hardware. It creates a new service delivery platform for the Cisco XR12000 Series Router to support high-performance layer 4 to layer 7 services.
The NAT64 Stateful translator on SMDC is an address translation mechanism that is capable of providing private IPv6 to public IPv4 address, in the order of millions of translations to support a large number of subscribers, at 8 Gbps full-duplex bandwidth throughput. NAT64 translation also enables unique IPv6 address provisioning constraints and N:1 IPv4 address sharing.
NAT64 allows IPv6-only clients to contact IPv4 servers using unicast UDP, TCP, or ICMP. The public IPv4 address can be shared among several IPv6-only clients. Stateful NAT64 is a mechanism for translating IPv6 packets to IPv4 packets, and vice-versa.

The asynchronous syslog communication feature enables proper ordering of messages testing on each node (LC, RP), non dropping of messages generated from multiple clients on each node (LC, RP) and checking performance, scalability and latency by sending log messages at incremental rates.
This feature enables the following:
Proper ordering of messages testing on MC min 4+1.
Non dropping of messages generated from multiple clients on MC min 4+1.
Syslogd_helper message handling capacity - flood lots of syslog messages using test client (logger), verify if no syslog message is lost ( specified rate as per new design).
1200/1500 msgs/sec from every node - restart restart/crash syslogd_helper on LCs and RP/correlatord and syslogd on RP.
Configure the routing protocol ospf. Configure 5k neighbors using sub interfaces. Perform interface flapping to generate log messages and check syslogd_helper performance.
Enable debug for few heavy processes - sysdb/gsp
Syslog Enhancement
The syslog enhancement feature enables to configure all different combinations of existing options under service timestamp log datetime and service timestamp debug datetime and check whether log messages have proper stamping by using keywords year in both service timestamp log datetime and service timestamp debug datetime to time stamp year in log message and severity in the existing cli logging <remote-host>.
This feature enables the following:
Config and delete year option and check whether year is present when configured and deleted.
Config and delete year option and check memory impact.
Enable the syslog archival feature and look into the impacts.
Configure multiple remote hosts and check whether they receive log messages with year when the feature is enabled and stop receiving the log messages with year when the feature is disabled.
Verify year stamping on a MC 4+1.
Configure remote host to receive log messages of only one severity or multiple severities.
Configure and delete severity for remote hosts and check memory impact.
Verify remote host severity on a MC 4+1.
New Hardware Features on the Cisco XR 12000 Series Router

See the Cisco IOS XR Getting Started Guide for the Cisco XR 12000 Series Router for procedures.
Exceeding Cisco testing—If you intend to test beyond the combined maximum configuration tested and published by Cisco, contact your Cisco Technical Support representative to discuss how to engineer a large-scale configuration for your purpose.
More power required for Cisco SIP line cards (SIP-401/501/600/601) on the Cisco XR 12000 Series Router—These line cards draw more power than previous generation line cards. Depending on the exact configuration of power entry modules (PEMs) and other cards in the chassis, there may not be enough power available when inserting a new card or removing a PEM. Before you insert a new card or remove a PEM, run the following command in admin mode:
RP/0/4/CPU0:router(admin)#show environment power-supply table Mon Sep 24 00:56:28.054 UTC 48V Current R/S/I Module (V) (A) 0/24/* PEM1 0 0 12000/6-AC-PEM= Intelligent AC PS PEM2 52 11 12000/6-AC-PEM= Intelligent AC PS 0/25/* PEM1 0 0 12000/6-AC-PEM= Intelligent AC PS PEM2 52 9 12000/6-AC-PEM= Intelligent AC PSTo display the power used or total power or remaining power in chassis. Use the command show power-mgr detail command in EXEC mode.

If this power is less than the figure given in Worst Case Redundant Power Available (the figure is displayed in the show environment power-supply table command output), the card can be safely inserted. As long as the Worst Case Redundant Power Available is not zero, a PEM can be powered down for replacement without impact.
Note
No alerts are issued if more cards are inserted than the PEMs can support. It is your responsibility to determine your power budget for the chassis before making any changes to it. Exceeding the power budget may result in the PEM being overloaded and cards powering down due to insufficient power being provided.
Per-interface Internet Control Message Protocol (ICMP) disable feature is not supported on the Cisco XR 12000 Series Router.
Online Diagnostics is not supported on the Cisco XR 12000 Series Router— If you execute the diagnostic command, an error appears stating that there is no online diagnostics process running on the router.
The rp mgmtethernet forwarding command is not supported on the Cisco XR 12000 Series Router.
Enabling the Lawful Interface feature triggers the L2-PRECAM-2-HW_RESOURCE_FAILURE message on Engine-3 linecards. This error reflects that your configuration has used up all available look-up registers (LUREGs).
There is no direct workaround for this issue as its a hardware limitation. Only way to recover from this issue is to reduce feature scale. You need to identify the features which use LUREG at PreCAM1 and remove one or more of the features depending on LUREG requirements of the feature being added.
mpls traffic engineering igp-intact command—This command must be used only when policy based tunnel selection is configured for all tunnels originating on the device. This CLI needs to be turned on under IGP (OSPF/ISIS) under the respective AFI.
Disable/Enable RSVP Message Checksum Starting with C isco IOS XR Software Release 4.0.2, RSVP will, by default, compute and set the checksum field in all outgoing RSVP messages. Also, RSVP will verify the checksum field on all RSVP messages received to insure RSVP message integrity.
A CLI is provided to override this Cisco IOS XR Software Release 4.0.2 default behavior and go back to pre Cisco IOS XR Software Release 4.0.2 behavior such that RSVP neither computes/sets the RSVP checksum on outgoing RSVP messages, nor verifies the checksum on received RSVP messages. The command to execute to revert to the pre- Cisco IOS XR Software Release 4.0.2 behavior is:
Router(config)#rsvp signalling checksum disable
Note
When the rsvp signalling checksum disable command is configured, RSVP sets a zero checksum in all outgoing RSVP messages, and ignores the checksum field on all received RSVP incoming messages.
Minimum Flash Disk Requirements When Upgrading to Release 4.3.0
Cisco IOS XR Software Release requires a 2-GB Flash Disk as a minimum. If your Cisco XR 12000 Series Router currently uses a 1-GB Flash Disk, you must upgrade it to 2-GB before upgrading to Cisco IOS XR Software Release . The PCMCIA 1-GB Flash Disk was the default size for the Cisco XR 12000 Series Router running Cisco IOS XR Software Release 3.6 and earlier.
In Cisco IOS XR Software Release 3.6 and later releases, disk partitioning is supported. Partitioning of a 2-GB disk is possible but not required. Partitioning of a 4-GB disk is required.
A 4-GB Flash Disk can be installed instead of the 2-GB for greater disk storage.
To upgrade from a 1-GB flash disk to a 2-GB or greater flash disk, refer to the Flash Disk Upgrade Tasks link on the following Cisco XR 12000 Series Router Installation and Upgrade URL:

Caveats
Caveats describe unexpected behavior in Cisco IOS XR Software releases. Severity-1 caveats are the most critical caveats; severity-2 caveats are less critical.
This section contains caveats that are generic to the Cisco IOS XR Release 4.3.0 software and those specific to the Cisco XR 12000 Series Router.
Cisco IOS XR Caveats
The following open caveats apply to Cisco IOS XR Software Release and are not platform specific:
CSCts29931
Basic Description:
Modifying the default-MDT in single commit drops traffic.
Symptom
If the default MDT for a VRF is changed and committed by using the mdt default ipv4 group command, forwarding over MDT may be impacted.
Conditions:
The default MDT has to be changed to a new group in a single commit (i.e., without deleting and re-adding).
Workaround:
Perform the following:
Execute the no mdt default ipv4 old-group command and commit.
Configure the new default MDT and commit.
Recovery:
Restarting the PIM or PIM6 will recover the issue.
CSCud48700
Basic Description:
Reverting to Cisco IOS XR Software R4.3.0.35i from R4.3.0.36i fails.
Symptom
Install operation or periodic backup fails.
Conditions:
This behavior is inconsistent.
Workaround:
