Create a BGP4+ Peer Group

1. Access global configuration mode.
   

   device# configure terminal

2. Access BGP configuration mode.
   

   device(config)# router bgp

3. 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.
4. 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.
5. Associate a neighbor with the peer group.
   

   device(config-bgp-router)# neighbor 2001:2018:8192::125 peer-group mypeergroup1

   This example shows the neighbor command, the IPv6 address of the neighbor, the peer-group keyword, and the name of the peer group (mypeergroup1).

6. Repeat step 5 as needed to associate more neighbors with the peer group.
7. Access IPv6 address family configuration mode.
   

   device(config-bgp-router)# address-family ipv6 unicast

8. Activate an IPv6 BGP session with the new peer group.
   

   device(config-bgp-ipv6u)# neighbor mypeergroup1 activate

Example

The following example summarizes the commands in this procedure

device# configure terminal
device(config)# router bgp
device(config-bgp-router)# neighbor mypeergroup1 peer-group
device(config-bgp-router)# neighbor mypeergroup1 remote-as 11
device(config-bgp-router)# neighbor 2001:2018:8192::125 peer-group mypeergroup1
device(config-bgp-router)# address-family ipv6 unicast
device(config-bgp-ipv6u)# neighbor mypeergroup1 activate
