RIB Commands on Cisco IOS XR Software

---

This chapter 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 Implementing RIB on Cisco IOS XR Software in Cisco IOS XR Routing Configuration Guide.

address-family next-hop dampening disable

To disable Routing Information Base (RIB) next-hop dampening, use the address-family next-hop dampening disable command in router configuration mode. To enable RIB next-hop dampening, use the no form of this command.

address-family {ipv4 | ipv6} next-hop dampening disable

no address-family {ipv4 | ipv6} next-hop dampening disable

Syntax Description

ipv4	Specifies IP Version 4 (IPv4) address prefixes.
ipv6	Specifies IP Version 6 (IPv6) address prefixes.

Defaults

RIB next-hop dampening is enabled.

Command Modes

Command History

Release	Modification
Release 3.4.0	This command was introduced on the Cisco CRS-1 and Cisco XR 12000 Series Router.
Release 3.5.0	No modification.

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 address-family next-hop dampening disable command to disable RIB next-hop dampening.

Examples

The following example shows how to disable RIB next-hop dampening for IPv6 address families:

RP/0/RP0/CPU0:router# configure 

RP/0/RP0/CPU0:router(config)# router rib 

RP/0/RP0/CPU0:router(config-rib)# address-family ipv6 next-hop dampening disable 

clear route

To clear routes from the IP routing table, use the clear route command in EXEC mode.

clear route [vrf {vrf-name | all}] {ipv4 | ipv6 | afi-all} {unicast | multicast | safi-all} [ip-address mask]

Syntax Description

vrf {vrf-name | all}	(Optional) Specifies a particular VPN routing and forwarding (VRF) instance or all VRF instances.

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.

show rib next-hop

To display registered next-hop notification addresses, use the show rib next-hop command in EXEC mode.

show rib [vrf {vrf-name | all}] [afi-all | ipv4 | ipv6] [unicast | multicast | safi-all] next-hop [client-name] [interface-type interface-instance | ip-address /prefix-length | ip-address mask | resolved | unresolved | looped | damped] [summary] [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. This is the default.
ipv6	(Optional) Specifies IP Version 6 address prefixes.
unicast	(Optional) Specifies unicast address prefixes. This is the default.
multicast	(Optional) Specifies multicast address prefixes.
safi-all	(Optional) Specifies unicast and multicast address prefixes.
client-name	(Optional) Name of the RIB client.
interface-type	(Optional) Interface type. For more information, use the question mark (?) online help function.
interface-number	(Optional) Either a physical interface instance or a virtual interface instance: •Physical interface instance. Naming notation is rack/slot/module/port and a slash between values is required as part of the notation. –rack: Chassis number of the rack. –slot: Physical slot number of the line card. –module: Module number. A physical layer interface module (PLIM) is always 0. –port: Physical port number of the interface. •Virtual interface instance. Number range varies depending on interface type. For more information about the syntax for the router, use the question mark (?) online help function.
ip-address	(Optional) Network IP address about which routing information should be displayed.
mask	(Optional) 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.
/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.
resolved	(Optional) Specifies resolved next hops.
unresolved	(Optional) Specifies unresolved next hops.
looped	(Optional) Specifies next hops that are looped.
damped	(Optional) Specifies next hops that are damped.
summary	(Optional) Specifies a summary of the next-hop information.
standby	(Optional) Displays standby information.
