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):
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter BGP view or BGP-VPN
instance view.
• Enter BGP view:
bgp as-number
• Enter BGP-VPN instance view:
a. bgp as-number
b. ip vpn-instance
vpn-instance-name
N/A
3. Create an EBGP peer group. group group-name external
By default, no EBGP peer group is
created.
4. Specify the AS number for the
group. peer group-name as-number
as-number
By default, no AS number is
specified.
If a peer group contains peers, you
cannot remove or change its AS
number.
5. Add a peer into the EBGP
peer group. peer ip-address group group-name
[ as-number as-number ]
By default, no peer exists in the
peer group.
The as-number as-number option,
if used, must specify the same AS
number as the peer group-name
as-number as-number command.
