DETAILED STEPS
Step 1 configure
Example:
RP/0/RSP0/CPU0:router# configure
Enters the global configuration mode.
Step 2 router bgp asn_id
Example:
RP/0/RSP0/CPU0:router(config)# router bgp 200
Specifies the BGP AS number and enters the BGP configuration mode, allowing you to configure the BGP routing
process.
Step 3 neighbor ip-address
Example:
RP/0/RSP0/CPU0:router(config-bgp)# neighbor 209.165.201.1
Places the router in neighbor configuration mode for BGP routing and configures the neighbor IP address 209.165.201.1
as a BGP peer.
Step 4 remote-as autonomous-system-number
Example:
RP/0/RSP0/CPU0:router(config-bgp-nbr)# remote-as 100
Creates a neighbor and assigns it a remote autonomous system number.
Step 5 update-source loopback
Example:
RP/0/RSP0/CPU0:router(config-bgp-nbr)# update-source loopback2
Allows BGP sessions to use the primary IP address from a particular interface as the local address.
Step 6 address-family l2vpn evpn
Example:
RP/0/RSP0/CPU0:router(config-bgp-nbr)# address-fmaily l2vpn evpn
