8.10.3 (Optional) Disabling Route Reflection Between Clients

If the clients of an RR are fully meshed, prohibiting route reflection among the clients can reduce
the link cost.
Context
The RR usually advertises the routes learned from clients to all non-clients and clients. If full-
mesh logical connections have been established between all the clients of the RR, the clients are
capable of sending routes to each other without the help of the RR. Route reflection can be
disabled between clients to reduce the stress on the RR.
Perform the following steps on the RR that is running BGP.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
bgp { as-number-plain | as-number-dot }
The BGP view is displayed.
Step 3 Run:
ipv4-family unicast
The IPv4 unicast address family view is displayed.
Step 4 Run:
undo reflect between-clients
Route reflection is disabled between clients.
If the clients of an RR have established full-mesh connections with each other, the undo reflect
between-clients command can be used to disable route reflection between clients in order to
reduce the link cost. By default, route reflection is enabled between the clients of an RR.
This command can only be configured on the RR.

8.10.4 (Optional) Configuring the Cluster ID for a Route Reflector
If several RRs are deployed in a cluster, assigning the same cluster ID to them can prevent route
loops.
