Configuration Guide - IP Routing
If the clients of the route reflector are full-meshed, you can use the undo reflect between-
clients command to disable the route reflection between the clients. This reduces cost.
By default, the route reflection between clients is enabled.
This command is used only on the reflector.

9.11.5 (Optional) Preventing BGP4+ Routes from Being Added into
the IPv6 Routing Table
Disabling BGP4+ route delivery to the IPv6 routing table on a route reflector (RR) can prevent
traffic from being forwarded by the RR, improving route advertisement efficiency.
Context
Usually, BGP4+ routes are delivered to the IPv6 routing table on the router to guide traffic
forwarding. If the router does not need to forward traffic, disable BGP4+ route delivery to the
IPv6 routing table on the router.
BGP4+ route delivery to the IPv6 routing table is generally disabled on RRs. An RR transmits
routes and forwards traffic within an AS. If the RR is connected to many clients and non-clients,

NOTE
When there are multiple route reflectors in a cluster, you can use the command to configure all the route
reflectors in this cluster with the same cluster ID. This avoids routing loops.
