Cisco ASR 9000 Series Routing Configuration Guide

Enters global configuration mode.
Step 2
router bgpas-number
Example:
RP/0/RSP0/CPU0:router(config)# router bgp 666
RP/0/RSP0/CPU0:router(config-bgp)#
Specifies the autonomous system number and enters the BGP configuration mode, allowing you to configure the BGP
routing process.
Step 3
vrfvrf-instance
Example:
RP/0/RSP0/CPU0:router(config-bgp)# vrf vrf-pe
RP/0/RSP0/CPU0:router(config-bgp-vrf)#
Configures a VRF instance.
Step 4
address-family {ipv4 | ipv6} unicast
Example:
RP/0/RSP0/CPU0:router(config-bgp-vrf)# address-family ipv4 unicast
RP/0/RSP0/CPU0:router(config-bgp-vrf-af)#
Specifies either an IPv4 or IPv6 address family unicast and enters address family configuration submode.
Step 5
label mode per-ce
Example:
RP/0/RSP0/CPU0:router(config-bgp-vrf-af)# label mode per-ce
RP/0/RSP0/CPU0:router(config-bgp-vrf-af)#
Configures resilient per-ce label allocation mode.
Step 6
Do one of the following:
•
end
•
commit
Example:
RP/0/RSP0/CPU0:router(config-bgp-vrf-af)# end
or
RP/0/RSP0/CPU0:router(config-bgp-vrf-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.
