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.

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
NoteThe 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:
Software Features Introduced in Cisco IOS XR Software Release 5.1.1
ACL Support in RPL Prefix Sets
Access Control List (ACL) type prefix set entries holds IPv4 or IPv6 prefix match specifications, each of which has an address and a wildcard mask. The address and wildcard mask is a standard dotted-decimal IPv4 or colon-separated hexadecimal IPv6 address. The set of bits to be matched are provided in the form of wildcard also called as inverted mask in which a binary 0 means a mandatory match and binary 1 means a do not match condition. The prefix set allows to specify contiguous and non-contiguous set of bits that should be matched in any route.
For more information on ACL Support in RPL Prefix Sets, see the Implementing Routing Policy chapter in the Cisco IOS XR Routing Configuration Guide for the Cisco XR 12000 Series Router. For more information on ACL Support in RPL Prefix Sets commands, see the Routing Policy Language Commands chapter in the Cisco IOS XR Routing Command Reference for the Cisco XR 12000 Series Router.
BGP Link-State
BGP Link-State (LS) is an Address Family Identifier (AFI) and Sub-address Family Identifier (SAFI) defined to carry interior gateway protocol (IGP) link-state database through BGP. BGP LS delivers network topology information to topology servers and Application Layer Traffic Optimization (ALTO) servers. BGP LS allows policy-based control to aggregation, information-hiding, and abstraction. BGP LS supports IS-IS and OSPFv2.
Note
IGPs do not use BGP LS data from remote peers. BGP does not download the received BGP LS data to any other component on the router.For more information on BGP LS, see the Implementing BGP chapter in the Cisco IOS XR Routing Configuration Guide for the Cisco XR 12000 Series Router. For more information on BGP LS commands, see the Border Gateway Protocol Commands chapter in the Cisco IOS XR Routing Command Reference for the Cisco XR 12000 Series Router.
BGP Multi-Instance Multi-AS Enhancement
The BGP Multi-Instance Multi-AS supports hosting of multicast-enabled VPNs, Multicast Distribution Tree sub-address family identifier (MDT-SAFI), Multicast Virtual Private Network sub-address family identifier (MVPN-SAFI), and Multicast Source Discovery Protocol (MSDP) queries on multiple BGP instances.
BGP Permanent Network
BGP permanent network feature supports static routing through BGP. BGP routes to IPv4 or IPv6 destinations (identified by a route-policy) can be administratively created and selectively advertised to BGP peers. These routes remain in the routing table until they are administratively removed.
For more information on BGP LS, see the Implementing BGP chapter in the Cisco IOS XR Routing Configuration Guide for the Cisco XR 12000 Series Router. For more information on BGP LS commands, see the Border Gateway Protocol Commands chapter in the Cisco IOS XR Routing Command Reference for the Cisco XR 12000 Series Router.
Auto-IP
In ring topology, when a device is inserted into the ring, the neighboring node interfaces require manual reconfiguration. The auto-IP feature addresses the problem of manually reconfiguring nodes during insertion, deletion, and movement of nodes within the ring. The auto-IP feature automatically provides IP addresses to the nodes inserted into the ring.
MPLS Static
The MPLS Static feature introduces ability to statically allocate MPLS label resources and provision static label switched paths (LSPs). MPLS static feature allows a user to:For information on MPLS Static configuration, refer Implementing MPLS Static module in Cisco IOS XR MPLS Configuration Guide for the Cisco XR 12000 Series Router. For information on the commands used for MPLS Static configuration, refer MPLS Static Commands module in Cisco IOS XR MPLS Command Reference for the Cisco XR 12000 Series Router.
MPLS TE Extended Admin Groups
The MPLS TE extended admin groups (EAG) configuration assigns EAG/AG name to bit-position and associates affinity-names with TE links. The configuration extends to assign names, up to 256, to TE links over the selected interface and assigns 32 names per attribute-set and index.
For more information on MPLS TE Extended Admin Groups, see the Implementing MPLS Traffic Engineering chapter in the Cisco IOS XR MPLS Configuration Guide for the Cisco XR 12000 Series Router. For more information on MPLS TE Extended Admin Groups commands, see the MPLS Traffic Engineering Commands chapter in the Cisco IOS XR MPLS Command Reference for the Cisco XR 12000 Series Router.
MPLS TE IPv6 Autoroute
The MPLS TE IPv6 Autoroute feature enables IPv4 and IPv6 routing over the same MPLS TEv4 tunnels in the core. This is done by exposing the IPv4 MPLS TE tunnels into the IPv6 IGP (IS-IS) topology as IPv6 forwarding adjacencies or autoroute announced tunnels (IGP shortcuts).
For more information on MPLS TE IPv6 Autoroute, see the Implementing MPLS Traffic Engineering chapter in the Cisco IOS XR MPLS Configuration Guide for the Cisco XR 12000 Series Router. For more information on MPLS TE IPv6 Autoroute commands, see the MPLS Traffic Engineering Commands chapter in the Cisco IOS XR MPLS Command Reference for the Cisco XR 12000 Series Router.
MPLS TE Usability Enhancements
MPLS traffic engineering command line interface and logging output messages are enhanced as follows:
- The show mpls traffic engineering commands display signaled-name and supports signaled-name filter.
- Ability to allow immediate teardown of all labelled switched paths ( LSPs) of the specified tunnel and to create new LSPs.
- Default behavior when affinity check fails at head-end is to reoptimize all LSP types.
- Logging output messages include MPLS TE tunnel signaled name.
- Logging of path change events and available bandwidth on the new for all auto-bandwidth operations.
- Auto-bandwidth logging output includes signaled name.
Stateful Path Computation Element
The stateful path computation element (PCE) describes a set of procedures by which a path computation client ( PCC) can report and delegate control of head-end tunnels sourced from the PCC to a PCE peer. The PCE peer can request the PCC to update and modify parameters of label switched paths (LSPs) it controls. The stateful model also enables a PCC to allow the PCE to initiate computations allowing the PCE to perform network-wide orchestration.
For more information on Stateful PCE, see the Implementing MPLS Traffic Engineering chapter in the Cisco IOS XR MPLS Configuration Guide for the Cisco XR 12000 Series Router. For more information on Stateful PCE commands, see the MPLS Traffic Engineering Commands chapter in the Cisco IOS XR MPLS Command Reference for the Cisco XR 12000 Series Router.
VRF Redirection to MPLS TE Tunnels
The VRF redirection to MPLS TE tunnels feature adds automatic route with IGP metric over the MPLS TE tunnels through autoroute destination configuration. The VRF redirection to MPLS TE tunnels maps VRF prefixes over TE tunnels in the core to reach the same egress provider edge (PE). This enables to load-balance prefix traffic on multiple tunnels based on equal cost multi-path (ECMP). VRF redirection also updates metric changes so that BGP can pickup the best next-hop based on installed route metric.
VRF redirection supports:
- automatic static routing of traffic over TE tunnel
- intra and inter-area/AS tunnels and installing multiple IPv4 routes in the routing information base (RIB) over tunnel, and a route to the tunnel’s destination
- implicit /32 mask for each route
- high availability, RP failover, and non-stop forwarding (NSF)
For more information on VRF Redirection to MPLS TE Tunnels, see the Implementing MPLS Traffic Engineering chapter in the Cisco IOS XR MPLS Configuration Guide for the Cisco XR 12000 Series Router. For more information on VRF Redirection to MPLS TE Tunnels commands, see the MPLS Traffic Engineering Commands chapter in the Cisco IOS XR MPLS Command Reference for the Cisco XR 12000 Series Router.
PE-PE Ingress Replication
The ingress PE replicates a C-multicast data packet belonging to a particular MVPN and sends a copy to all or a subset of the PEs that belong to the MVPN. A copy of the packet is tunneled to a remote PE over a Unicast Tunnel to the remote PE.
IR-MDT represents a tunnel that uses IR as the forwarding method. It is usually, one IR-MDT per VRF, with multiple labeled switch paths (LSP) under the tunnel.
When PIM learns of Joins over the MDT (using either PIM or BGP C-multicast Routing), it downloads IP S,G routes to the VRF table in MRIB, with IR-MDT forwarding interfaces. Each IR-MDT forwarding interface has a LSM-ID allocated by PIM. Currently, LSM-ID is managed by mLDP and can range from 0 to 0xFFFFF (20-bits). For IR, the LSM-ID space is partitioned between mLDP and IR. For IR tunnels, the top (20th) bit is always be set, leading to a range of 0x80000 to 0xFFFFF. mLDP’s limit is 0 to 0x7FFFF.
Software Feature Enhancements
These software feature enhancements are introduced in Cisco IOS XR Software Release 5.1.1.
- ROMMON updates
Refer Software/Firmware Compatibility Matrix information at http://www.cisco.com/web/Cisco_IOS_XR_Software/index.html link, for details of minimum ROMMON requirements and for the firmware version of new SPAs. For more information about upgrading and downgrading ROMMON firmware, see the Upgrading and Downgrading ROM Monitor and Boothelper chapter in Cisco IOS XR ROM Monitor Guide for the Cisco XR 12000 Series Router.
New Hardware Features on the Cisco XR 12000 Series Router
There is no new hardware feature added in the Cisco IOS XR Software Release 5.1.1 for the Cisco XR 12000 Series Router platform.
Important Notes
- Default timestamp setting—The timestamp prompt that precedes console output is enabled by default. To disable the timestamp prompt, use the no service timestamp command. For more information, refer to the Cisco IOS XR System Management Command Reference for the Cisco XR 12000 Series Router.
- Country-specific laws, regulations, and licenses—In certain countries, use of these products may be prohibited and subject to laws, regulations, or licenses, including requirements applicable to the use of the products under telecommunications and other laws and regulations; customers must comply with all such applicable laws in the countries in which they intend to use the products.
- Migrating from Cisco IOS to Cisco IOS XR Software on the Cisco XR 12000 Series Router—When migrating a Cisco XR 12000 Series Router from Cisco IOS to Cisco IOS XR Software, follow the instructions provided in Migrating from Cisco IOS to Cisco IOS XR Software on the Cisco XR 12000 Series Router.
- Card fan controller, and RSP removal—For all card removal and replacement (including fabric cards, line cards, fan controller, and RSP) follow the instructions provided by Cisco to avoid impact to traffic. 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 maximum 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:
To display the power used or total power or remaining power in chassis. Use the command show power-mgr detail command in EXEC 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 PSIf you plan to insert a new card, locate the entry for the card to be inserted and note the power consumed by it. 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.RP/0/4/CPU0:router#show power-mgr detail Mon Sep 24 00:53:54.518 UTC Power management summary ------------------------ Powershelf type: AC Power Supplies Operating phase: RUNNING_PHASE Feature state : Enabled Operating mode : NON-REDUNDANT Total supply power: 1900 W Route processors: 60 W Linecards: 240 W Chassis components: 477 W Total inuse power: 777 W Remaining: 1123 W PEM1 present, but unpowered PEM2 present, supplying up to 1900 watts: uptime 0d01h39m Slot Cardtype Watts Status ---- -------- ----- ------ 1 12000-SIP-601= 240 powered 4 PRP= 60 powered 16 GSR6-CSC= 56 powered 17 GSR6-CSC= 56 powered 18 GSR6-SFC= 45 powered 19 GSR6-SFC= 45 powered 20 GSR6-SFC= 45 powered 24 GSR6-ALRM= 26 powered 25 GSR6-ALRM= 26 powered 28 GSR6-BLOWER= 178 powered
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.
- Starting from Cisco IOS XR Software Release 4.0.0, the hw-module location <LOC> reload warm command is disabled. As a result, the warm reload feature also has been disabled.
Minimum Flash Disk Requirements When Upgrading to Release
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:
http://www.cisco.com/en/US/products/ps6342/prod_installation_guides_list.html
Caveats
Caveats describe unexpected behavior in Cisco IOS XR Software releases. Severity-1 caveats are the most serious caveats; severity-2 caveats are less serious.
This section contains caveats that are generic to the Cisco IOS XR Release 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:
- CSCuh97547 Basic Description: BGP process crash @ bgp_fwdentry_info on heavy route flaps. Symptom BGP process crash observed when router undergoes route churn. Route churn as a result of triggers like clear bgp command may also hit this issue. Conditions: Router running Cisco IOS XR Software Release 5.1.1 software with label RPF feature configured AND BGP undergoes heavy route churn with prefix scale of around 420K v4 and 60k v6 routes. Workaround: None.
- CSCuj77052 Basic Description: IPv6 sessions with ND framed prefix delegation go down post RPFO. Symptom Immediately after an RPFO, IPv6 PPPoE sessions are brought down by the router and IPv6 traffic stops flowing on the sessions. This is accompanied by the following error message on the console (where addresses displayed will depend on the router's configuration): %ROUTING-RIB-3-ECMP_ERR_ADD : Path add exceed max number of paths supported by protocol. Table 0xXXXXXXXX, prefix XXXX:X:X::/64, protocol subscriber, intf 0xXXXXXXXX, tunnelid 0, nexthop_table 0xXXXXXXXX, nexthop fe80::XXX:XXXX:XXXX:XXX Conditions: This issue occurs with IPv6-only or dual stack PPPoE subscriber sessions when the ipv6_rib process is restarted or following an RP failover. This is observed when "ipv6 nd framed-prefix-pool" is used to delegate the prefix. Workaround: None.
- CSCul82815 Basic Description: VTY_disconnect is not able to clear allocated TTY. Symptom VTY line not getting cleared up on child channel exit. New child channel allocates a next available VTY line and very soon all VTY lines would be exhausted. Conditions: Using SSH client which support multichannel (openssh 5.0 or higher version). Workaround:
- CSCum59810 Basic Description: qos_ma crash if input Satellite QoS offload configured under ICL. Symptom qos_ma process crash observed during router boot-up. This happens with an incorrect service-policy configuration on an ICL interface (interface connected to Satellite). Conditions: The following mis-configuration can cause this crash:
interface TenGigE0/7/0/8 cdp nv service-policy input Sat-QoS-Offload satellite-fabric-link satellite 100Workaround: Configure as below:interface TenGigE0/7/0/8 cdp nv satellite-fabric-link satellite 100- CSCum70594 Basic Description: Self-originated External LSA counter underflow. Symptom
In some situations, the counter that keeps the number of redistributed prefixes can be decremented multiple times for a given prefix when prefix is not redistributed anymore. The following may occur:Conditions: Double decrement of the counter happens if the prefix that has been redistributed by OPFv3 changes the source protocol in RIB first, which is followed by the RIB removal of the prefix. Both of these need to happen in a very short period of time. Workaround: Restart the OSPFv3 process.- CSCum71861 Basic Description: The show ospf vrf xxx command output routes summary shows negative intra-area. Symptom show ospf vrf route summary command output may sometime show negative path counter value. Conditions: Router may show negative value for intra-Area path counter maintained by OSPF. Intermittently, observed this issue showing up after clearing OSPF session for VRFs. Workaround: None.
- CSCum11308 Basic Description: L2fab-DH: Satellite stuck in "probing" after changing encapsulation type. Symptom After changing the encaps type of an L2 satellite-fabric-link, the state of the interface (as displayed in show nv satellite protocol discovery) is Probing. Conditions: Changing the encapsulation type of the L2 satellite-fabric-link without shutting the interface or removing the nV ICPE configuration. Workaround: Shut down the interface (or remove the nv ICPE configuration) before changing the encapsulation type of an L2 fabric satellite-fabric-link.
- CSCum42969 Basic Description: Policy-map configured through XML has value mismatch. Symptom After configuring policy-map discard-class through XML request, user may notice mismatch in the value shown under show running-config. Conditions: Configuring policy-map discard-class using XML on a router running Cisco IOS XR Software Release 5.1.1. Workaround: Use CLI instead of XML to configure policy-map discard-class.
