Configuring a Route Reflector

Configuring a Route Reflector Cluster

You can connect multiple route reflectors in a route reflector cluster. Within a

cluster, IBGP route reflectors must be connected in a full-mesh topology.

To configure a route reflector in a cluster, you establish a peer-to-peer session

with one or more route reflectors in the same cluster. You can do this with the

BCC or Site Manager.

Using the BCC

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

go to the BGP prompt (for example,

box; ip; /jointfilesconvert/97454/bgp

) 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 route reflector.

as_number

is the AS where the remote reflector resides. (Because the local and

remote reflectors reside in the same AS, BGP recognizes that this is an IBGP

session.)

At the session-specific prompt, enter the following command to specify that the

remote route reflector is an internal peer (that is, located in the same cluster):

peer-mode reflector-internal

For example, the following command sequence defines a peer-to-peer session

between two route reflectors (represented by addresses 2.2.2.2 and 2.2.2.3)

located in the same cluster in AS 2:

/jointfilesconvert/97454/bgp#

peer local 2.2.2.2 remote 2.2.2.3 as 2

peer/2.2.2.2/2.2.2.3#

peer-mode reflector-internal

peer/2.2.2.2/2.2.2.3#
