Configuring a Route Reflector

To avoid the high cost of a full-mesh topology to support IBGP speakers within a

large AS, you can configure a router to function as an IBGP route reflector. An

IBGP speaker that needs to communicate with other BGP speakers in the AS

establishes a peer-to-peer RR client session with the IBGP route reflector.

You configure an IBGP speaker to be a route reflector or RR client and establish

peer-to-peer connections between reflectors and clients as described under the

following topics:

Configuring a Single Route Reflector in an AS

An IBGP route reflector (RR) is an IBGP speaker that has established a

peer-to-peer session with an IBGP speaker defined as an RR client.

Configuring an RR Client 8-9

Note:

When you configure a session between two IBGP route reflectors or an

RR and an RR client, you must configure both ends of the session. Otherwise,

events may occur that cause BGP to shut down the session.
