Step Command Remarks
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
address family view.
address-family ipv6 [ unicast ] N/A
4. Configure the router as a route
reflector and specify a peer or
peer group as its client.
peer { group-name |
ipv6-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.

Ignoring the ORIGINATOR_ID attribute
A router is configured with a router ID. When a router receives a BGP route update, it compares the
router ID with the ORIGINATOR_ID attribute in the route update. If they are the same, the router drops the
route update to avoid routing loops. However, for some networks (such as firewall networks) to operate
correctly, BGP must not drop but accept such route updates. For BGP to accept such route updates, you
must configure BGP to ignore the ORIGINATOR_ID attribute in BGP route updates.
To ignore the ORIGINATOR_ID attribute (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. Ignore the ORIGINATOR_ID
attribute. peer { group-name | ip-address }
ignore-originatorid
By default, BGP does not ignore
the ORIGINATOR_ID attribute.
Make sure that this command does
not result in a routing loop.
After you execute this command,
BGP also ignores the
CLUSTER_LIST attribute.
