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: 

Enter system view 

— 

Enter BGP view 

bgp as-number 

— 

Create an eBGP peer group 

group group-name external 

Required 

Specify the AS number for the 
group 

peer group-name as-number 
as-number 

Required 

Add a peer into the group 

peer ip-address group 
group-name  

Required 

 

All the added peers have the same AS number as that of the peer group.  

 

Follow these steps to configure an eBGP peer group using the second approach: 

Enter system view 

— 

Enter BGP view 

bgp as-number 

— 

Create an eBGP peer group 

group group-name external 

Required 

Specify an AS number for a 
peer 

peer ip-address as-number 
as-number 

Required 

Add the peer into the group 

peer ip-address group 
group-name [ as-number 
as-number ] 

Required 

The AS number can be either 
specified or not specified in the 
command. If specified, the AS 
number must be the same as that 
specified for the peer with the 
peer ip-address as-number 
as-number command.
