When you specify that you want information about a specific network, more detailed statistics are displayed. The following is sample output from the show route command when entered with an IP address:

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 this 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.

RIB quarantining detects mutually recursive routes and quarantines the last route that actually completes the mutual recursion. The quarantined route is periodically evaluated to see if the mutual recursion has gone away. If the recursion still exists, the route remains quarantined. If the recursion has gone away, the route is released from quarantine.
Use the show route quarantined command to display mutually recursive (looping) routes.

To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.
Use the show route resolving-next-hop command to perform a recursive route lookup on the supplied destination address and return information on the next immediate router (next-hop) to the destination.
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 static
To display the current static routes of the Routing Information Base (RIB), use the show route static command in EXEC mode.
show route [vrf {vrf-name | all}] [afi-all | ipv4 | ipv6] [unicast | multicast {topology topo-name} | safi-all] static [standby]
Syntax Description
Defaults
If a vrf vrf-name is not specified, the current static routes of the RIB are displayed for the default IPv4 unicast VRF.
Command Modes

Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.
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.

Related Commands
show route summary
To display the current contents of the Routing Information Base (RIB), use the show route summary command in EXEC mode.
show route [vrf {vrf-name | all}] [afi-all | ipv4 | ipv6] [unicast | multicast {topology topo-name} | safi-all] summary [detail] [standby]
Syntax Description
Defaults
If a vrf vrf-name is not specified, the contents of the RIB are displayed for the default IPv4 unicast VRF.
Command Modes
EXEC
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.
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 manner—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.
