Configuring BGP Route Reflection

You can configure route reflection as an alternative to BGP confederations.

Route reflection supports both internal and external BGP routing groups.

Syntax:

set bgp

      internal peer <IP Address>

            peer-type {no-client-reflector | none | reflector-client}

      cluster-id {<IP Address> | off}

      default-med {<0-65535> | off}

      default-route-gateway {<IP Address> | off}

Parameters:

Parameter

Description

internal peer <IP Address>

Specifies the peer router.

peer-type {no-client-reflector | none | reflector-client}

Specifies if this is a Route Reflector client.

  • no-client-reflector

    Peer is a 'non-client' Route Reflector.

    Enter this option to specify that a reflection client's routes are reflected only to internal BGP peers in other groups.

    Clients in the group are assumed to be direct iBGP peers of each other.

  • none

    Peer is not a Route Reflector.

    Enter this option, if you do not want to specify route reflection.

  • reflector-client

    Peer is a Route Reflector.

    Enter this option to specify that the local router acts as a route reflector for the group of peers named.

    That is, the local router is the route reflection server, and the named peers are route reflection clients.

    Normally, the routing daemon readvertises, or reflects, routes it receives from one of its clients to all other iBGP peers, including the other peers in that client's group.

cluster-id {<IP Address> | off

Configures or disables the cluster ID used for route reflection.

The cluster ID default is that of the Router ID.

Override the default if the cluster has more than one route reflector.

default-med {<0-65535> | off}

Configures or disables the Multi-Exit Discriminator (MED) metric used to advertise routes through BGP.

default-route-gateway {<IP Address> | off}

Configures of disables the default BGP route.

This route has a higher rank than any configured default static route for this router.

If you do not want a BGP peer considered for generating the default route, use this command:

peer <IP Address> suppress-default-originate on
