Configuring a BGP route reflector

If an AS has many BGP routers, configure them as a cluster. To reduce IBGP connections, configure one

of them as a route reflector and others as clients.

To improve availability, you can specify multiple route reflectors for a cluster. The route reflectors in the

cluster must have the same cluster ID to avoid routing loops.

To configure a BGP route reflector (IPv4):

Step Command Remarks

1. Enter system view.

system-view N/A

2. Enter BGP view or BGP-VPN

instance view.

• Enter BGP view:

bgp as-number

• Enter BGP-VPN instance view:

a. bgp as-number

b. ip vpn-instance

vpn-instance-name

N/A

3. Enter BGP IPv4 unicast

instance view or BGP-VPN

IPv4 unicast instance view.

ipv4-family [ unicast ] N/A

4. Configure the router as a route

reflector and specify a peer or

peer group as its client.

peer { group-name | ip-address }

reflect-client

By default, no route reflector or

client is configured.

5. Enable route reflection

between clients.

reflect between-clients

By default, route reflection

between clients is enabled.

6. (Optional.) Configure the

cluster ID of the route reflector.

reflector cluster-id { cluster-id |

ip-address }

By default, a route reflector uses its

own router ID as the cluster ID.

To configure a BGP route reflector (IPv6):

Step Command Remarks

1. Enter system view.

system-view N/A

2. Enter BGP view.

bgp as-number N/A

3. Enter BGP IPv6 unicast

instance view.

ipv6-family [ unicast ] N/A
