Configure the local router
as the RR and configure
the peer group as the
client of the RR
peer group-name
reflect-client
Required
By default, no RR or its
client is configured.
Enable route reflection
between clients
reflect between-clients
Optional
By default, route reflection
is enabled between
clients.
Configure cluster ID of an
RR
reflector cluster-id
cluster-id
Optional
By default, an RR uses its
own router ID as the
cluster ID.
Caution:
z 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.
z 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.
