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.

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.

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.

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.

Syntax Description

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

ip-address	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.

Defaults

If a vrf vrf-name is not specified, routes are cleared from the default IPv4 unicast VRF.

show rib tables

To display all tables known to the Routing Information Base (RIB), use the show rib tables command in EXEC mode.

show rib [afi-all | ipv4 | ipv6] tables [standby]

Syntax Description

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.
standby	(Optional) Displays standby information.

Defaults

No default behavior or values

Release	Modification
Release 3.3.0	This command was introduced on the Cisco CRS-1 and Cisco XR 12000 Series Router.
Release 3.4.0	The ipv4, ipv6, and standby keywords were added.

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 rib tables command to display all tables known to the RIB, including table attributes. Attributes include VPN routing and forwarding (VRF) instance, address family, and maximum prefix information.

Table 135 describes the significant fields shown in the display.

Table 135 show rib tables Field Descriptions 

Field	Description
VRF	Name of the VRF instance.
AFI/SAFI	Address family instance.
Table ID	ID of the RIB table.
PrfxLmt	Configured prefix limit for the RIB table.
PrfxCount	Number of configured prefixes in the RIB table.
PrfxLmtNotified	Message sent when prefix limit is exceeded.
FwdRfrncd	Forward referenced. If Yes is indicated, a table has been created by RIB because a client has registered for the table, but RIB has not heard from the router space infrastructure (RSI) about the table. RSI manages the tables.
Deleted	If Yes is indicated, the table has been deleted in the RSI but RIB has not cleared the information.

show route

To display the current routes in the Routing Information Base (RIB), use the show route command in EXEC mode.

show route [vrf {vrf-name | all}] [afi-all | ipv4 | ipv6] [unicast | multicast | safi-all] [protocol [instance] | ip-address [mask] | ip-address/prefix-length] [standby] [detail]

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.
protocol	(Optional) Name of a routing protocol. If you specify a routing protocol, use one of the following keywords: •bgp •eigrp •isis •ospf •rip •static •local •connected
instance	(Optional) Number or name used to identify an instance of the specified protocol.
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.
standby	(Optional) Displays standby information.
detail	(Optional) Displays detailed information for the specified prefix.

Defaults

If a vrf vrf-name is not specified, routes are displayed for the default IPv4 unicast VRF.
