Implementing BGP
Example:
RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)#
Enters global configuration mode.
Step 2
router bgpas-number
Example:
RP/0/RP0/CPU0:router(config)# router bgp 666
RP/0/RP0/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/RP0/CPU0:router(config-bgp)# vrf vrf-pe
RP/0/RP0/CPU0:router(config-bgp-vrf)#
Configures a VRF instance.
Step 4 address-family {ipv4 | ipv6} unicast
Example:
RP/0/RP0/CPU0:router(config-bgp-vrf)# address-family ipv4 unicast
RP/0/RP0/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/RP0/CPU0:router(config-bgp-vrf-af)# label-mode per-ce
RP/0/RP0/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/RP0/CPU0:router(config-bgp-vrf-af)# end
or
RP/0/RP0/CPU0:router(config-bgp-vrf-af)# commit
Saves configuration changes.
