can be filled. You can use the neighbor peer-type command to explicitly configure a peer
type for a peer group.
Alternatively, you can implicitly configure the peer type of a peer group by either of the
following methods:
•
Configure a remote AS for the peer group.
•
Assign a peer with a configured remote AS as a member of the peer group.
In both of these implicit cases, the remote AS is combined with the local AS, the configured
confederation ID, and the configured confederation peers to determine the peer type of
the peer group.
neighbor peer-type
• Use to specify a peer type for a peer group.
• This command is supported only for peer groups; it is not available for individual peers.
• Use the internal keyword to specify that peers must be in the same AS or, if
confederations are employed, in the same sub-AS in the same confederation.
• Use the external keyword to specify that peers must be in a different AS.
• Use the confederation keyword to specify that peers must be in a different sub-AS in
the same confederation. Use this keyword only if confederations are employed.
• This command takes effect immediately. If the command changes the peer type of
the peer group, all BGP sessions for members of that peer group are automatically
bounced.
• All the members of the peer group inherit the characteristic configured with this
command. It cannot be overridden for a specific peer, because the command applies
only to peer groups.
• Example
host1(config-router)#neighbor promispeers peer-type internal
• Use the no version to remove the configuration from the peer group.
• See neighbor peer-type
Assigning a Description
You can associate a description with a BGP neighbor or a peer group. This is a convenient
way to store minimal pertinent information about the neighbor.
neighbor description
• Use to associate a textual description of up to 80 characters with a BGP neighbor or
peer group.
• If you specify a BGP peer group by using the peerGroupName argument, all the members
of the peer group inherit the characteristic configured with this command unless it is
overridden for a specific peer.
