3.15.4 Configuring Route Reflection for the Routes of the BGP VPN
Instance
The premise of enabling BGP VPNv4 route reflection is that the RR has established the MP-
IBGP connections with all its clients (CEs).
Context
Do as follows on the RR:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
bgp as-number
The BGP view is displayed.
Step 3 Run:
ipv4-family vpn-instance vpn-instance-name
The BGP VPN instance view is displayed.
Step 4 Enable route reflection for the routes of the BGP VPN instance on the RR.
l Run the peer group-name reflect-client command to enable route reflection if the RR
establishes the IBGP connection with the peer group consisting of all Client CEs.
l Run the peer ipv4-address reflect-client command repeatedly to enable route reflection if
the RR establishes the IBGP connection with each PE rather than the peer group.
Step 5 (Optional) Run:
reflect between-clients
Route reflection between the Client CEs is enabled.
By default, route reflection between the Client CEs is enabled.
If the Client CEs are fully connected, you can use the undo reflect between-clients command
to disable route reflection between the clients to reduce the cost.
Step 6 (Optional) Run:
reflector cluster-id cluster-id
