Configuring a VPRN Service with CLI
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.
