Configuring A Bgp Mdt Route Reflector - HP A8800 Configuration Manual

Configuring a BGP MDT route reflector

BGP MDT peers in the same AS must be fully meshed to maintain connectivity. However, when many BGP
MDT peers exist in an AS, connection establishment among them may cause great expenses. To reduce
connections between them, you can configure one of them as a route reflector and specify other routers
as clients. The clients establish BGP MDT connections with the route reflector, and the route reflector
forwards (reflects) BGP MDT routing information between clients. In this way, the clients need not to be
fully meshed. Furthermore, you can disable client-to-client reflection to reduce overloads if the clients
have been fully meshed.
The route reflector and its clients form a cluster. In general, a cluster has only one route reflector whose
router ID identifies the cluster. However, you can configure several route reflectors in a cluster to improve
network reliability, and they must have the same cluster ID configured to avoid routing loops.
Perform the following configuration on the PE.
To configure a BGP MDT route reflector:
Step
1. Enter system view.
2. Enter BGP view.
3. Enter BGP MDT sub-address
family view.
4. Configure the local device as
a route reflector and specify
its clients.
5. Disable route reflection
between clients.
6. Configure the cluster ID of the
route reflector.
Displaying and maintaining multicast VPN
