Cisco IOS XR Routing Configuration Guide

Step 3

address-family {ipv4 unicast | ipv4 multicast |

| ipv6 unicast | ipv6 multicast}

Example:

RP/0/RP0/CPU0:router(config-bgp)#

address-family ipv4 unicast

Enters address family configuration mode for the specified

address family.

Step 4

bgp dampening [

half-life

[

reuse suppress

max-suppress-time

] | route-policy

route-policy-name

]

Example:

RP/0/RP0/CPU0:router(config-bgp-af)# bgp

dampening 30 1500 10000 120

Configures BGP dampening for the specified address

family.

Step 5

end

commit

Example:

RP/0/RP0/CPU0:router(config-bgp-af)# end

RP/0/RP0/CPU0:router(config-bgp-af)# commit

Saves configuration changes.

• When you issue the end command, the system prompts

you to commit changes:

Uncommitted changes found, commit them before

exiting(yes/no/cancel)?

[cancel]:

–

Entering yes saves configuration changes to the

running configuration file, exits the configuration

session, and returns the router to EXEC mode.

–

Entering no exits the configuration session and

returns the router to EXEC mode without

committing the configuration changes.

–

Entering cancel leaves the router in the current

configuration session without exiting or

committing the configuration changes.

• Use the commit command to save the configuration

changes to the running configuration file and remain

within the configuration session.

Step 6

multicast | all | tunnel} | all {unicast |

multicast | all | labeled-unicast} | vpnv4

]]

flap-statistics

Example:

RP/0/RP0/CPU0:router# show bgp flap statistics

Displays BGP flap statistics.
