Implementing MPLS VPNs over IP Tunnels

Configuring the Backbone Carrier Core for IP Tunnels

Configuring the backbone carrier core requires setting up connectivity and routing functions for the CSC core
and the CSC-PE routers. To do so, you must complete the following high-level tasks:
• Verify IP connectivity in the CSC core.
• Configure IP tunnels in the core.
• Configure VRFs .
• Configure multiprotocol BGP for VPN connectivity in the backbone carrier.

Verifying MPLS VPN over IP

To verify the configuration of end-end (PE-PE) MPLS VPN over IP provisioning, use the following show
commands:
• show cef recursive-nexthop
• show bgp ipv4 tunnel
• show bgp vpnv4 unicast summary
• show bgp vrf v1 ipv4 unicast summary
• show bgp vrf v1 ipv4 unicast prefix
• show cef vrf v1 ipv4 prefix
• show cef ipv6 recursive-nexthop
• show bgp vpnv6 unicast summary
• show bgp vrf v1 ipv6 unicast summary
• show bgp vrf v1 ipv6 unicast prefix
• show cef vrf v1 ipv6 prefix

Configuring Source Pool Address for MPLS VPNs over IP Tunnels

Perform this task to configure the Multiple Tunnel Source Address.
