Configuring Bgp Confederation - H3C S7500 Series Operation Manual

Operation Manual – Routing Protocol
H3C S7500 Series Ethernet Switches
Enter system view
Enter BGP view
Configure the local router
as the RR and configure
the peer group as the
client of the RR
Enable route reflection
between clients
Configure cluster ID of an
RR
Caution:
Normally, no fully-meshed connection is required between an RR and a client. A
route is reflected by an RR from a client to another client. If an RR and a client are
fully connected, you can disable the reflection between clients to reduce the cost.
Normally, there is only one RR in a cluster. In this case, the router ID of the RR is
used to identify the cluster. Configuring multiple RRs can improve the network
stability. If there are multiple RRs in a cluster, use related command to configure
the same cluster ID for them to avoid routing loopback.
