Peer templates for a non-default VRF instance
You can create peer templates to add multiple neighbors at a time to the non-default VRF instance that you create.
1 Enable BGP, and assign the AS number to the local BGP speaker in CONFIGURATION mode, from 1 to 65535 for 2 byte, 1 to
4294967295 | 0.1 to 65535.65535 for 4 byte, or 0.1 to 65535.65535 in dotted format.
router bgp as-number
2 Enter the CONFIG-ROUTER-VRF mode to create a peer template for the non-default VRF instance that you create.
vrf vrf-name
3 Create a peer template by assigning a neighborhood name to it in CONFIG-ROUTER-VRF mode.
template template-name
4 Add a neighbor as a remote AS in ROUTER-TEMPLATE mode, from 1 to 65535 for 2 byte, 1 to 4294967295 | 0.1 to 65535.65535 for
4 byte, or 0.1 to 65535.65535 in dotted format.
neighbor ip-address
5 Add a remote neighbor, and enter the AS number in ROUTER-TEMPLATE mode.
remote-as as-number
• To add an EBGP neighbor, congure the as-number parameter with a number dierent from the BGP as-number congured in
the router bgp as-number command.
• To add an IBGP neighbor, congure the as-number parameter with the same BGP as-number congured in the router bgp
as-number
command.
6 (Optional) Add a text description for the template in ROUTER-TEMPLATE mode.
description text
7 Assign a peer-template with a peer-group name from which to inherit to the neighbor in ROUTER-NEIGHBOR mode.
inherit template template-name
8 Enable the neighbor in ROUTER-BGP mode.
neighbor ip-address
9 Enable the peer-group in ROUTER-NEIGHBOR mode.
no shutdown
When you add a peer to a peer group, it inherits all the peer group congured parameters. When you disable a peer group, all the peers
within the peer template that are in the Established state move to the Idle state. A neighbor cannot become a part of a peer group if it has
any of these commands congured:
• advertisement-interval
• next-hop-self
• route-map out
• route-reflector-client
• send-community
A neighbor may keep its conguration after it is added to a peer group if the neighbor conguration is more specic than the peer group
and if the neighbor conguration does not aect outgoing updates.
To display the peer-group conguration assigned to a BGP neighbor, enter the show ip bgp peer-group peer-group-name
command. The show ip bgp neighbor command output does not display peer-group congurations.
