l If the RR establishes the MP-IBGP connection with each PE rather than peer group, run the
peer peer-ipv4-address reflect-client command multiple times to enable route reflection.
Step 5 Run:
undo policy vpn-target
The received VPNv4 routes are not filtered based on VPN targets.
Step 6 (Optional) Run:
rr-filter extended-list-number
The reflection policy is configured for the RR.
----End
3.11.5 Checking the Configuration
Prerequisite
The configurations of RR are complete.
Procedure
l Run the display bgp vpnv4 all peer [ [ ipv4-address ] verbose ] command to view
information about the BGP VPNv4 peer on the RR or the client PEs.
l Run the display bgp vpnv4 all routing-table peer peer-ipv4-address { advertised-
routes | received-routes } [ statistics ] command to view information about the VPNv4
routes received from the peer or the VPNv4 routes advertised to the peer on the RR or the
client PEs.
l Run the display bgp vpnv4 all group [ group-name ] command to view information about
the VPNv4 peer group on the RR.
----End
Example
If the configurations are successful,
l You can find that the status of the MP-IBGP connections between the RR and all client
PEs is Established after running the display bgp vpnv4 all peer command on the RR or
client PEs.
l You can find that the RR and each client PE can receive and send VPNv4 routing
information between each other after running the display bgp vpnv4 all routing-table
peer command on the RR or the client PEs.
l If the peer group is configured, you can view information about the group members and
find that the status of the BGP connections between the RR and the group members is
Established after running the display bgp vpnv4 all group command on the RR.
3.12 Configuring Route Reflection to Optimize the VPN
Access Layer
This section describes how to configure the BGP route reflection on the PE that connect to
multiple CEs to reflect the routes of VPN instances.
