How to Configure MPLS VPNs over IP Tunnels

Configuring Inter-AS and CSC support over IP Tunnels

These tasks describe how to configure Inter-AS and CSC support over IP tunnels:

•Configuring the ASBRs to Exchange VPN-IPv4 Addresses for IP Tunnels, page MPC-285(required)

•Configuring the Backbone Carrier Core for IP Tunnels, page MPC-288

•Configuring CSC-PE Routers for IP Tunnels, page MPC-288

Configuring the ASBRs to Exchange VPN-IPv4 Addresses for IP Tunnels

Perform this task to configure an external Border Gateway Protocol (eBGP) autonomous system boundary router (ASBR) to exchange VPN-IPv4 routes with another autonomous system for IP tunnels

Note This procedure is supported on the Cisco XR 12000 Series Router.
