Task ID
router rib
To enter Routing Information Base (RIB) configuration mode, use the router rib command in XR Config mode. To remove all RIB configurations and terminate the RIB routing process, use the no form of this command.
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
Task ID
rump always-replicate
To enable replication from uRIB to muRIB as usual even after features such as MTR are configured, use the rump always-replicate command in router configuration mode. To diable replication from uRIB to muRIB, use the no form of this command.
Syntax Description
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
Configuring the rump always-replicate command allows routers in a network to be upgraded to multitopology routing gradually without a flag day where all routers need to be configured at the same time without major service disruption. When rump always-replicate is configured, replicated routes are added into the muRIB with the lowest admin distance. So if protocols are populating the muRIB, they continue to do so. For the same route, protocol routes win over replicated routes because of higher admin distance.
If an unwanted more specific route comes from the uRIB, optionally provide an access list through which the replicated routes are run. If the route passes the access list, the route is replicated by RUMP.
Task ID
show lcc statistics
To view results of a label consistency checker (lcc) background scan, use the show lcc statistics command in XR EXEC mode.
Syntax Description
Command History
Usage Guidelines

The IS-IS node uses one of its own interface addresses in this TLV. A loopback address is preferred among interfaces configured under IS-IS. When other networking devices calculate IP routes, they can store the IP address as the originator address with each route in the routing table.
The following example shows the output from the show route command for a specific IP address on a router configured with IS-IS. Each path that is shown under the Routing Descriptor Blocks report displays two IP addresses. The first address (10.0.0.9) is the next-hop address; the second is the originator IP address from the advertising IS-IS router.

To display the current static routes of the Routing Information Base (RIB), use the show route static command in XR EXEC mode.
show route [ vrf { vrf-name | all } ] [ afi-all | ipv4 | ipv6 ] [ unicast | multicast | { topology topo-name } | safi-all ] static [ standby]
Syntax Description
vrf { vrf-name | all }
(Optional) Specifies a particular VPN routing and forwarding (VRF) instance or all VRF instances.
afi-all
(Optional) Specifies all address families.
ipv4
(Optional) Specifies IP Version 4 address prefixes.
ipv6
(Optional) Specifies IP Version 6 address prefixes.
unicast
(Optional) Specifies unicast address prefixes.
multicast
(Optional) Specifies multicast address prefixes.
safi-all
(Optional) Specifies unicast and multicast address prefixes.
standby
(Optional) Displays standby information.
Command Default
If a vrf vrf-name is not specified, the current static routes of the RIB are displayed for the default IPv4 unicast VRF.
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
Use the show route static command to display information about static routes in the routing table.
The topology keyword must be accompanied by the ipv4 multicast keywords, except when the afi-all keyword or the safi-all keyword is specified.

show route summary
To display the current contents of the Routing Information Base (RIB), use the show route summary command in XR EXEC mode.
show route [ vrf { vrf-name | all } ] [ afi-all | ipv4 | ipv6 ] [ unicast | multicast | { topology topo-name } | safi-all ] summary [ detail ] [ standby ]
Syntax Description
vrf { vrf-name | all }
(Optional) Specifies a particular VPN routing and forwarding (VRF) instance or all VRF instances.
afi-all
(Optional) Specifies all address families.
ipv4
(Optional) Specifies IP Version 4 address prefixes.
ipv6
(Optional) Specifies IP Version 6 address prefixes.
unicast
(Optional) Specifies unicast address prefixes.
multicast
(Optional) Specifies multicast address prefixes.
safi-all
(Optional) Specifies unicast and multicast address prefixes.
detail
(Optional) Displays a detailed summary of the contents of the RIB, including the number of paths and some protocol-specific route attributes.
standby
(Optional) Displays standby information.
Command Default
If a vrf vrf-name is not specified, the contents of the RIB are displayed for the default IPv4 unicast VRF.
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
Use the show route summary command to display information about routes in the routing information base.
When a route summary is needed frequently—for instance, in a polling situation—use the show route summary command without the detail keyword. The detail keyword is used less frequently for verification purposes, because it is much more expensive (in bandwidth), requiring a scan of the entire routing database.
The topology keyword must be accompanied by the ipv4 multicast keywords, except when the afi-all keyword or the safi-all keyword is specified.
