Configure 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.
There are three approaches for configuring an eBGP peer group:
z Create the eBGP peer group, specify its AS number, and add peers into it. All the added peers
share the same AS number.
z Create the eBGP peer group, specify an AS number for a peer, and add the peer into the peer
group.
z Create the eBGP peer group and add a peer into it with an AS number specified.
Follow these steps to configure an eBGP peer group using the first approach:
