RIB Commands

This module describes the commands used to display and clear information in the Routing Information Base (RIB).

For detailed information about RIB concepts, configuration tasks, and examples, see the Implementing RIB on Softwaremodule in Routing Configuration Guide for Cisco NCS 6000 Series Routers.

Command Default

RIB next-hop dampening is enabled.

Command Modes

Network IP address about which routing information should be displayed.

mask

Network mask specified in either of two ways:

Network mask can be a four-part, dotted-decimal address. For example, 255.0.0.0 indicates that each bit equal to 1 means the corresponding address bit is a network address.

Network mask can be indicated as a slash (/) and number. For example, /8 indicates that the first 8 bits of the mask are 1s, and the corresponding bits of the address are the network address.

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.

rump always-replicate [access-list]

no rump always-replicate [access-list]

(Optional) Name of the access list.

Command Default

Replication from uRIB to muRIB is enabled.

Command Modes

Command History

Release

Modification

Release 5.0.0

This command was introduced.

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.

Field

Description

S*

Code indicating how the route was derived. See the code legend preceding the output. In this case, the route was derived from a static (candidate default).

[1/0]

First number in the brackets is the administrative distance of the information source; the second number is the metric for the route.

1.0.0.0/16

Address and prefix length of the remote network.

MgmtEthernet 0/5/CPU0/0

Specifies the interface through which the specified network can be reached.

C

Code indicating how the route was derived. See the code legend preceding the output. In this case, the route was connected.

L

Code indicating how the route was derived. See the code legend preceding the output. In this case, the route was local.

O

Code indicating how the route was derived. See the code legend preceding the output. In this case, the route was on-demand routing (ODR).

E2

Code indicating how the route was derived. See the code legend preceding the output. In this case, the route was OSPF external type 2.

8.2.8.0/24

Address and prefix length of the remote network connected to the static route.

via 3.3.3.1

Specifies the address of the next router to the remote network.

13:14:59

Specifies the last time the route was updated.

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

 RP/0/RP0/CPU0:router# show route 10.0.0.0
  
  Routing entry for 10.0.0.0/16
    Known via "connected", distance 0, metric 0 (connected)
    Installed Mar 22 22:10:20.906
    Routing Descriptor Blocks
      directly connected, via GigabitEthernet0/0/0/0
        Route metric is 0
    No advertising protos.

Intermediate System-to-Intermediate System (IS-IS) includes an IP address typed length value (TLV) in its link-state packet (LSP) that helps identify the node injecting the route into the network. 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.

 RP/0/RP0/CPU0:router# show route 10.0.0.1

Command

Description

show route

Displays the current contents of the routing table.

show route quarantined

To display mutually recursive (looping) routes, use the show route quarantined command in XR EXEC mode.

show route [ ipv4 | ipv6 ] [ unicast | { } | safi-all ] quarantined [ ip-address/prefix-length] | ip-address mask ] [ standby ]

Syntax Description

ipv4

(Optional) Specifies IP Version 4 address prefixes.

ipv6

(Optional) Specifies IP Version 6 address prefixes.

unicast

(Optional) Specifies unicast address prefixes.

safi-all

(Optional) Specifies unicast address prefixes.

ip-address

(Optional) IP address about which looping routes information is to be displayed.

/ prefix-length

(Optional) Length of the IP address prefix. A decimal value that indicates how many of the high-order contiguous bits of the address compose the prefix (the network portion of the address). A slash (/) must precede the decimal value.

(Optional) Network mask applied to the ip-address argument.

standby

(Optional) Displays standby information.

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.

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.

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.
