Configuring a BGP Route Reflector

If an AS has many BGP routers, you can configure them as a cluster and configure one of them as a
route reflector and others as clients to reduce iBGP connections.
To enhance network reliability and prevent single point failures, you can specify multiple route reflectors
for a cluster. The route reflectors in the cluster must have the same cluster ID specified to avoid routing
loops.
Follow these steps to configure a BGP route reflector:
To do...
Enter system view

reflector and specify a
peer/peer group as its client
