Guide.
Configuring VPRN BGP Group and Neighbor Parameters
A group is a collection of related VPRN BGP peers. The group name should be a descriptive name
for the group. Follow your group, name, and ID naming conventions for consistency and to help
when troubleshooting faults.
All parameters configured for a peer group are applied to the group and are inherited by each peer
(neighbor), but a group parameter can be overridden on a specific neighbor-level basis.
After a group name is created and options are configured, neighbors can be added within the same
autonomous system to create IBGP connections and/or neighbors in different autonomous systems
to create EBGP peers. All parameters configured for the peer group level are applied to each
neighbor, but a group parameter can be overridden on a specific neighbor basis.
Configuring Route Reflection
Route reflection can be implemented in autonomous systems with a large internal BGP mesh to
reduce the number of IBGP sessions required. One or more routers can be selected to act as focal
points, for internal BGP sessions. Several BGP-speaking routers can peer with a route reflector. A
route reflector forms peer connections to other route reflectors. A router assumes the role as a
route reflector by configuring the
required unless you want to disable reflection to specific peers.
If you configure the
neighbors are members of the cluster. The route reflector cluster ID is expressed in dotted decimal
notation. The ID should be a significant topology-specific value. No other command is required
unless you want to disable reflection to specific peers.
If a route reflector client is fully meshed, the
enabled to stop the route reflector from reflecting redundant route updates to a client.
