Huawei quidway s7700 - Configuring Route Reflection to Optimize the VPN Access Layer; Establishing the Configuration Task

Procedure
l Run the display bgp vpnv4 all peer [ [ ipv4-address ] verbose ] command to check
information about the BGP VPNv4 peer on the RR or the Client PEs.
l Run the display bgp vpnv4 all routing-table peer ipv4-address { advertised-routes |
received-routes } command or display bgp vpnv4 all routing-table statistics command
to check information about the routes received from the peer or the routes advertised to the
peer on the RR or the Client PEs.
l Run the display bgp vpnv4 all group [ group-name ] command to check information about
the VPNv4 peer group on the RR.
----End
Example
If the configurations succeed,
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.
3.15 Configuring Route Reflection to Optimize the VPN
Access Layer
If a PE and the connected CEs are in the same AS, you can deploy a BGP route RR to reduce
the number of IBGP connections between CEs and facilitate maintenance and management.
3.15.1 Establishing the Configuration Task
Before configuring an RR to optimize the VPN access layer, familiarize yourself with the
applicable environment, complete the pre-configuration tasks, and obtain the required data. This
can help you complete the configuration task quickly and accurately.
Applicable Environment
If a PE and multiple CEs accessing the PE are located in the same AS, to reduce the IBGP
connections between the CEs, the PE can be configured as an RR to reflect the routes of the
VPN instance, and the CEs can be configured as clients, which are called Client CEs. This
simplifies and facilitates network maintenance and management.
Pre-configuration Tasks
Before configuring route reflection to optimize the VPN access layer, complete the following
tasks:
