Step Command

Remarks

7.

Configure the CE as a client
of the RR.

peer { group-name | ip-address
[ mask-length ] } reflect-client

By default, no RR or RR client is
configured, and the PE does not
advertise routes learned from the

IBGP peer CE to other IBGP

peers, including VPNv4 IBGP
peers. The PE advertises routes

learned from the CE to other

IBGP peers only when you
configure the IBGP peer CE as a

client of the RR.
Configuring an RR does not
change the next hop of a route.

To change the next hop of a
route, configure an inbound

policy on the receiving side.

8.

(Optional.) Enable route

reflection between clients.

reflect between-clients

Route reflection between clients
is enabled by default.

9.

(Optional.) Configure the

cluster ID for the RR.

reflector cluster-id { cluster-id |
ip-address }

By default, the RR uses its own
router ID as the cluster ID.
If multiple RRs exist in a cluster,

use this command to configure
the same cluster ID for all RRs in

the cluster to avoid routing loops.

2.

Configure the CE:

2.

Enter BGP view.

bgp as-number N/A

3.

Configure the PE as an IBGP

peer.

peer { group-name | ip-address
[ mask-length ] } as-number
as-number

By default, no BGP peer is
created.

4.

Create the BGP IPv4 unicast
family and enter its view.

address-family ipv4 [ unicast ]

By default, the BGP IPv4 unicast
family is not created.

5.

Enable IPv4 unicast route
exchange with the specified

peer or peer group.

peer { group-name | ip-address
[ mask-length ] } enable

By default, BGP does not
exchange IPv4 unicast routes

with any peer.

6.

(Optional.) Configure route
redistribution.

import-route protocol
[ { process-id | all-processes }

[ med med-value | route-policy
route-policy-name
] * ]

A CE must redistribute its routes
to the PE so the PE can advertise

them to the peer CE.
