Implementing BGP
DETAILED STEPS
Step 1 configure
Step 2
router bgp as-number
Example:
RP/0/RP0/CPU0:router(config)# router bgp 120
Specifies the autonomous system number and enters the BGP configuration mode, allowing you to configure the BGP
routing process.
Step 3 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 4 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 5 address-family{ipv4 {labeled-unicast | unicast | mdt | | mvpn | rt-filter | tunnel} | ipv6 {labeled-unicast | mvpn
| unicast}}
Example:
RP/0/RP0/CPU0:router(config-bgp-nbr)# address-family ipv6 unicast
Enters neighbor address family configuration mode for the specified address family. Use either ipv4 or ipv6 address
family keyword with one of the specified address family sub mode identifiers.
IPv6 address family mode supports these sub modes:
• labeled-unicast
• mvpn
• unicast
IPv4 address family mode supports these sub modes:
• labeled-unicast
• mdt
• mvpn
• rt-filter
• tunnel
• unicast
Step 6 Use one of these commands:
• send-community-ebgp
