After you create a peer group, you can use any of the commands beginning with the keyword neighbor to
configure that peer group.
When you add a peer to a peer group, it inherits all the peer group’s configured parameters.
A neighbor cannot become part of a peer group if it has any of the following commands are configured:
• neighbor advertisement-interval
• neighbor distribute-list out
• neighbor filter-list out
• neighbor next-hop-self
• neighbor route-map out
• neighbor route-reflector-client
• neighbor send-community

Enable the neighbor.
Add an enabled neighbor to the peer
group.
Add a neighbor as a remote AS.

AS-number: 0-65535 (2-Byte) or
1-4294967295 | 0.1- 65535.65535 (4-Byte)
To add an external BGP (EBGP) neighbor, configure the
as-number parameter with a number different from the BGP
as-number configured in the router bgp as-number command.
To add an internal BGP (IBGP neighbor, configure the as-number
parameter with the same BGP as-number configured in the
router bgp as-number command.
A neighbor may keep its configuration after it was added to a peer group if the neighbor’s configuration is
more specific than the peer group’s, and the neighbor’s configuration does not affect outgoing updates.
Note: When you configure a new set of BGP policies for a peer group, always reset the peer
group by entering the clear ip bgp peer-group peer-group-name command in EXEC Privilege
mode.
