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, and 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.

Note
If you are running Cisco IOS XR Software on a Cisco XR120xx system with SIP 600, 401, 501, or 601, you must upgrade the fabric cards. For ROMMON, MBUS, and Fabric Downloader versions, see the "Other Firmware Support" section.
Check the firmware needed by running the show fpd package command in admin mode.
Firmware Support
To check the firmware code running on the Cisco XR 12000 Series Router, run the show fpd package command in admin mode.
RP/0/0/CPU0:router(admin)#show fpd package
- Line cards (LCs) For Engine 3 line card: 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
- Requirement of Cisco IOS Image Level and Boot Helper Version for Migration
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:
What's New in Cisco IOS XR Release 5.1.x
See the following links for a summary of new and changes features and commands in Release 5.1.x:
Software Features Introduced in Cisco IOS XR Software Release 5.1.0
EIGRP Multi-Instance
The Enhanced Interior Gateway Routing Protocol (EIGRP) Multi-Instance feature allows multiple process instances to handle different routing instances and service the same VRF. Each process instance handles the routing instances configured under it. The multiple EIGRP process instance implementation allows to configure the EIGRP using a virtual-name in addition to an autonomous-system number.
Graceful Restart for OSPFv3
The OSPFv3 Graceful Restart feature preserves the data plane capability in these circumstances:
- RP failure resulting in a switch-over to the backup processor
- Planned OSPFv3 process restart, such as a restart resulting from a software upgrade or downgrade
- Unplanned OSPFv3 process restart, such as a restart resulting from a process crash
This feature supports nonstop data forwarding on established routes while the OSPFv3 routing protocol restarts. Therefore, this feature enhances high availability of IPv6 forwarding.
Protocol Shutdown Mode
In this mode the OSPFv3 operation is completely disabled. This is accomplished by flushing self-originated link state advertisements (LSAs), immediately bringing down local OSPFv3-supported interfaces, and clearing the Link State Database (LSDB). The non-local LSDB entries are removed by OSPFv3, These are not flooded (MaxAged).
The protocol shutdown mode can be invoked either manually through the protocol shutdown command that disables the protocol instance or when the OSPFv3 process runs out of memory. These events occur when protocol shut down is performed:
- The local Router LSA and all local Link LSAs are flushed. All other LSAs are eventually aged out by other OSPFv3 routers in the domain.
- OSPFv3 neighbors that are currently exchanging their database with the local router are brought down with the Kill_Nbr event.
- Empty Hello packets are immediately sent to each neighbor that has an active adjacency.
- The LSA database from that OSPFv3 instance is cleared.
- All routes from RIB that were installed by OSPFv3 are purged.
- The router will not respond to any OSPF control packets it receives from neighbors while in protocol shutdown state.
Protocol Restoration
The method of restoring the protocol is dependent on the trigger that originally invoked the shut down. If the OSPFv3 was shut down using the protocol shutdown command, then use the no protocol shutdown command to restore OSPFv3 back to normal operation. If the OSPFv3 was shutdown due to a Critical Memory message from the sysmon, then a Normal Memory message from sysmon, which indicates that sufficient memory has been restored to the processor, restores the OSPFv3 protocol to resume normal operation.
These events occur when the OSPFv3 is restored:
IS-IS IPv6 Loop Free Alternate Fast Re-route
The IPv6 Loop Free Alternate fast Re-route (IPv6 LFA FRR) feature supports fast re-route (FRR) for IPv6 unicast in Cisco IOS XR Software on the E5 line cards. LFA is supported over the frame relay Interface. IPv6 FRR helps to minimize traffic loss during convergence for pure IPv6 unicast prefixes. The IPv6 LFA FRR supports both per-prefix LFA and per-link LFA modes. IPv6 LFA FRR for IS-IS is enabled by configuring the fast re-route commands under the IS-IS IPv6 address family configuration mode.
For more information on configuring IS-IS IPv6 Loop Free Alternate Fast Re-route, see the Implementing IS-IS chapter in the Cisco IOS XR Routing Configuration Guide for the Cisco XR 12000 Series Router. For complete command reference of the IS-IS IPv6 Loop Free Alternate Fast Re-route commands, see the BGP Commands chapter in the Cisco IOS XR Routing Command Reference for the Cisco XR 12000 Series Router.
IS-IS LDP Remote Loop Free Alternate Fast Re-route
The LDP remote loop free alternate fast re-route (rLFA FRR) feature enables computation of non-directly connected neighbor (more than one hop away) as LFA backup path to protect a given prefix’s primary path, and setting up of labeled [backup] LSP with the remote next-hop for the protected prefix. The rLFA FRR helps to minimize traffic loss in some topologies (example: ring topology) during convergence after a failure triggered topology change.
The use of a non-directly connected neighbor as LFA backup/next-hop is termed as Remote LFA or Extended LFA. For a given protected link, the IGP computes remote LFA backup by means of PQ algorithm. The IGP updates the routing information base (RIB) [ per-prefix ] with LFA protection information [per-path]. The LDP initiates/establishes a targeted session with the remote LFA [PQ] node to exchange labels for prefixes. The LDP also sets up MPLS forwarding for protected prefixes along with their remote LFA/PQ backup paths, if any. Upon FRR trigger, pre-programmed remote LFA backup path is activated to achieve convergence (within 50 milliseconds) and is used until the IGP converges to new primary path(s).
For more information on configuring IS-IS LDP Remote Loop Free Alternate Fast Re-route, see the Implementing IS-IS chapter in the Cisco IOS XR Routing Configuration Guide for the Cisco XR 12000 Series Router. For complete command reference of the IS-IS LDP Remote Loop Free Alternate Fast Re-route commands, see the IS-IS Commands chapter in the Cisco IOS XR Routing Command Reference for the Cisco XR 12000 Series Router.

OSPFv3 Sham Link Support for MPLS VPN
OSPFv3 sham link represents the VPN backbone as a single point-to-point connection between the two PEs. OSPFv3 treats the sham link as a point-to-point unnumbered interface, similar to virtual-link. When OSPFv3 sham link is configured, ensure that the route to the remote endpoint of the sham-link exists in the VRF RIB.
If the route to the remote endpoint exists, sham link interface is brought up. If the route to the remote endpoint of the sham-link is removed from the VRF RIB, OSPFv3 receives redistribution callback and brings the sham link down.
Graceful Restart Procedure over the Sham-link
OSPFv3 treats the sham link as any other interface during the switch-over or process restart. OSPFv3 assumes that all the configured sham links are UP and tries to form an adjacency over them.
If the sham link is down prior to the switch-over, OSPFv3 sends the Hello packets to the remote endpoint. Once the final convergence signal is received from the RIB, OSPFv3 keeps the sham link either up or down based on the BGP route for each configured sham link in the RIB.
OSPFv3 installs the high AD routes over the sham link only after the BGP convergence is complete.
Resilient Per-CE Label Allocation Mode
The Resilient Per-CE Label Allocation is an extension of the Per-CE label allocation mode to support Prefix Independent Convergence (PIC) and load balancing.
At present, the three label allocation modes, Per-Prefix, Per-CE, and Per-VRF have these drawbacks:In the Resilient Per-CE label allocation scheme, BGP installs a unique rewrite label in LSD for every unique set of CE paths or nexthops. There may be one or more prefixes in BGP table that points to this label. BGP also installs the CE paths (primary) and optionally a backup PE path into RIB. FIB learns about the label rewrite information from LSD and the IP paths from RIB.
In steady state, labeled traffic destined to the resilient per-CE label is load balanced across all the CE nexthops. When all the CE paths fail, any traffic destined to that label will result in an IP lookup and will be forwarded towards the backup PE path, if available. This action is performed on the label independently of the number of prefixes that may point to the label, resulting in the Prefix-Independent Convergence (PIC) behavior during primary paths failure.
4arg
4arg is Cisco’s implementation of Object Size Checking (OSC). OSC is a useful static analysis utility and a critical runtime defense for the detection and prevention of buffer overflows. 4arg captures buffer overflows (at runtime) that are otherwise undetected by code analysis tools and human review. 4arg also carries a reporting and logging component.
4arg refers to a theoretical fourth argument to a string copy function representing the destination buffer size.
