Configuring Route Reflection to Optimize the VPN Backbone Layer

Configuring Route Reflection to Optimize the VPN Backbone Layer

Using an RR can reduce the number of MP IBGP connections between PEs. This not only reduces the burden of PEs, but also facilitates network maintenance and management.

Pre-configuration Tasks

Before configuring route reflection to optimize the VPN backbone layer, complete the following tasks:

  • Configure the routing protocol for the MPLS backbone network to implement IP interworking between devices on the backbone network.

  • Establish LSP tunnels between the RR and all client PE devices.

Configuration Procedure

All the following configuration tasks are mandatory. An RR can be any device, for example, a P, PE, or ASBR device.
