Conguring Peer Groups
To congure multiple BGP neighbors at one time, create and populate a BGP peer group.
An advantage of peer groups is that members of a peer group inherit the conguration properties of the group and share same update
policy.
A maximum of 256 peer groups are allowed on the system.
Create a peer group by assigning it a name, then adding members to the peer group. After you create a peer group, you can congure route
policies for it. For information about conguring route policies for a peer group, refer to Filtering BGP Routes.
NOTE
: Find Sample Congurations for enabling peer groups at the end of this chapter.
