Configuring an EBGP peer group
If peers in an EBGP group belong to the same external AS, the EBGP peer group is a pure EBGP peer
group; if not, it is a mixed EBGP peer group.
Use one of the following methods to configure an EBGP peer group:
•
Create the EBGP peer group, specify its AS number, and add peers into it. All the added peers
share the same AS number.
•
Create the EBGP peer group, specify an AS number for a peer, and add the peer into the peer
group.
•
Create the EBGP peer group and add a peer into it with an AS number specified.
