Create a BGP4 Peer Group

A BGP4 peer group is a collection of IPv4 neighbors that have the same attributes and parameters.

1. Access global configuration mode.
   

   device# configure terminal

2. Access BGP configuration mode.
   

   device(config)# router bgp

3. Specify the autonomous system in which your device resides.
   

   device(config-bgp-router)# local-as 1000

4. Create a peer group.
   

   device(config-bgp-router)# neighbor mypeergroup1 peer-group 

   This example shows the neighbor command, the peer group name (mypeergroup1), and the peer-group keyword.
5. Specify the autonomous system number (ASN) of the peer group.
   

   device(config-bgp-router)# neighbor mypeergroup1 remote-as 11

   This example associates ASN 11 to the new peer group.
6. Associate a neighbor with the peer group.
   

   device(config-bgp-router)# neighbor 10.2.2.2 peer-group mypeergroup1

   This example shows the neighbor command, the IP address of the neighbor, the peer-group keyword, and the name of the peer group (mypeergroup1).
7. Repeat step 6 as needed to associate more neighbors with the peer group.

Example

The following example summarizes the commands in this procedure

device# configure terminal
device(config)# router bgp
device(config-bgp-router)# local-as 1000
device(config-bgp-router)# neighbor mypeergroup1 peer-group
device(config-bgp-router)# neighbor mypeergroup1 remote-as 11
device(config-bgp-router)# neighbor 10.2.2.2 peer-group mypeergroup1
