Configuring BGP route reflection
Configuring a BGP route reflector
Perform this task to configure a BGP route reflector and its clients. The route reflector and its clients
automatically form a cluster identified by the router ID of the route reflector. The route reflector
forwards route updates among its clients.
To improve availability, you can specify multiple route reflectors for a cluster. The route reflectors in
the cluster must have the same cluster ID to avoid routing loops.
To configure a BGP route reflector (IPv4 unicast/multicast address family):
Step
1.
Enter system view.
