Configuring Bgp Route Reflection - HP FlexFabric 12900E Series Configuration Manual

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.
2. Enter BGP IPv4 unicast
address
BGP-VPN
address family view, or BGP
IPv4 multicast address family

3. Configure the router as a
route reflector and specify a
peer or peer group as its
client.
4. Enable
between clients.
