Configuring a Route Reflector

Configuring Multiple RR Clusters in an AS

An AS can contain multiple IBGP route reflector clusters. In an AS with multiple

clusters:

• Each cluster has a unique ID.

• Within each cluster, RR clients are connected to RRs in a tree topology.

• Within the AS, clusters are connected in arbitrary topologies. (From the point

of view of the topology, a cluster is a mini-AS. Like an AS, a cluster can be

configured in an arbitrary way.)

To configure multiple RR clusters in an AS, complete the following steps:

Associate a route reflector with a cluster.

Establish a peer-to-peer session with a reflector in another cluster.

Using the BCC

To associate a route reflector with a cluster, go to the BGP prompt (for example,

box; ip; /jointfilesconvert/97454/bgp

) and enter

cluster-id

<cluster_id>

cluster_id

is the ID number (from 0 through 4,294,967,295) of the cluster where

the route reflector resides.

For example, the following command associates the route reflector with cluster 5:

/jointfilesconvert/97454/bgp#

cluster-id 5

/jointfilesconvert/97454/bgp#

To establish a peer-to-peer session with a route reflector in another cluster, go to

the BGP prompt and enter:

peer local

<local_reflector_address>

remote

<remote_reflector_address>

<as_number>

local_reflector_address

is the IP address on the local route reflector.

remote_reflector_address

is the IP address on the remote reflector in another

cluster.

as_number

is the AS where the remote reflector resides.
