DETAILED STEPS
Step 1
configure
Example:
RP/0/RP0/CPU0:router# configure
Enters the Global Configuration mode.
Step 2
router bgp autonomous-system-number
Example:
RP/0/RP0/CPU0:router(config)# router bgp 120
RP/0/RP0/CPU0:router(config-bgp)#
Enters Border Gateway Protocol (BGP) configuration mode allowing you to configure the BGP routing process.
Step 3
address-family { ipv4 tunnel }
Example:
RP/0/RP0/CPU0:router(config-bgp)# address-family ipv4 tunnel
RP/0/RP0/CPU0:router(config-bgp-af)#
Configures IPv4 tunnel address family.
Step 4
