8.10.5 (Optional) Preventing BGP Routes from Being Added into
the IP Routing Table
Disabling BGP route delivery to the IP routing table on an RR can prevent traffic from being
forwarded by the RR, improving route advertisement efficiency.
Context
Usually, BGP routes are delivered to the IP routing table on the router to guide traffic forwarding.
If the router does not need to forward traffic, disable BGP route delivery to the IP routing table
on the router.
BGP route delivery to the IP 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, the
route transmission task will consume a lot of CPU resources of the RR and cause the RR unable
to implement traffic forwarding. To improve the efficiency of route transmission, disable BGP
route delivery to the IP routing table on the RR to make the RR dedicated to route transmission.

Issue 02 (2014-09-30)
NOTE
To ensure that a client can learn the routes reflected by an RR, the Cluster ID configured on the RR must
be different from the Cluster ID of the client (By default, the client uses its Router ID as the cluster ID). If
the Cluster ID is the same as the Cluster ID of the client, the client discards received routes.
