Configuring an IBGP peer group
After you create an IBGP peer group and then add a peer into it, the system creates the peer in BGP view
and specifies the local AS number for the peer.

Enter system view.
system-view

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 approaches 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.
To configure an EBGP peer group using Approach 1:
Step Command
1.
Enter system view.
system-view
2.
Enter BGP view.
bgp
as-number
3.
Create an EBGP peer group.

4.

group.

5.
Add the peer into the group.

NOTE:
•
Do not specify any AS number for a peer before adding it into the peer group.
•
All of the added peers have the same AS number as that of the peer group.
