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:
•
Method 1—Create an EBGP peer group, specify its AS number, and add peers into it. All the
added peers have the same AS number. All peers in the peer group have the same AS number
as the peer group. You can specify an AS number for a peer before adding it into the peer group.
The AS number must be the same as that of the peer group.
•
Method 2—Create an EBGP peer group, specify an AS number for a peer, and add the peer
into the peer group. Peers added in the group can have different AS numbers.
•
Method 3—Create an EBGP peer group and add a peer with an AS number into it. Peers
added in the group can have different AS numbers.
To configure an EBGP peer group by using Method 1 (IPv4 unicast address family):
Step
1. Enter system view.
2. Enter BGP instance view or
BGP-VPN instance view.
3. Create an EBGP peer group.
