Configure Interfaces for VPN Routing
On each PE router, you must configure an interface over which the VPN traffic travels between the PE and CE routers.
The sections that follow describe how to configure interfaces for VPNs:
- General Configuration for VPN Routing
- Configure Interfaces for Layer 3 VPNs
- Configure Interfaces for Carrier-of-Carriers VPNs
- Configure Unicast RPF on VPN Interfaces
The configuration described in General Configuration for VPN Routing applies to all types of VPNs. For Layer 3 VPNs and carrier-of-carriers VPNs, complete the configuration described in that section before proceeding to the interface configuration sections specific to those topics.
