Step 5
configure
Example:
RP/0/RP0/CPU0:router# configure
Enters global configuration mode.
Step 6
router bgp as-number
Example:
RP/0/RP0/CPU0:router(config)# router bgp 120
Enters BGP configuration mode, allowing you to configure
the BGP routing process.
Step 7
bgp router-id ip-address
Example:
RP/0/RP0/CPU0:router(config-bgp)# bgp router-id
192.168.70.24
Configures the local router with a specified router ID.
Step 8
address-family {ipv4 unicast | ipv4 multicast |
ipv4 tunnel | ipv4 mdt | ipv6 unicast | ipv6
multicast | vpnv4 unicast | vpnv6 unicast}
Example:
RP/0/RP0/CPU0:router(config-bgp)#
address-family ipv4 unicast
Enters global address family configuration mode for the
specified address family.
Step 9
exit
Example:
RP/0/RP0/CPU0:router(config-bgp-af)# exit
Exits the current configuration mode.
Step 10
neighbor ip-address
Example:
RP/0/RP0/CPU0:router(config-bgp)# neighbor
172.168.40.24
Places the router in neighbor configuration mode for BGP
routing and configures the neighbor IP address as a BGP
peer.
Step 11
remote-as as-number
Example:
RP/0/RP0/CPU0:router(config-bgp-nbr)# remote-as
2002
Creates a neighbor and assigns a remote autonomous
system number to it.
Step 12
address-family {ipv4 unicast | ipv4 multicast |
ipv4 labeled-unicast | ipv4 tunnel | ipv4 mdt |
ipv6 unicast | ipv6 multicast | ipv6
labeled-unicast | vpnv4 unicast | vpnv6
unicast}
Example:
RP/0/RP0/CPU0:router(config-bgp-nbr)#
address-family ipv4 unicast
Enters address family configuration mode for the specified
address family.
