Configuring An Ipv6 Mpls L3Vpn Over A Gre Tunnel - HP FlexNetwork HSR6600 Configuration Manual

Configuring an IPv6 MPLS L3VPN over a GRE tunnel

Network requirements
CE 1 and CE 2 belong to VPN 1. The PEs support MPLS, while the P router does not support MPLS
and provides only IP features.
On the backbone, use a GRE tunnel to encapsulate and forward packets for IPv6 MPLS L3VPN.
Configure tunnel policies on the PEs, and specify the tunnel type for VPN traffic as GRE.

Configuration procedure
1. Configure an IGP on the MPLS backbone to ensure IP connectivity among the PEs and the P
router.
This example uses OSPF. (Details not shown.)
# Execute the display ospf peer command to verify that OSPF adjacencies in Full state have
been established between PE 1, P, and PE 2. Execute the display ip routing-table command
to verify that the PEs have learned the routes to the loopback interfaces of each other. (Details
not shown.)
2. Configure basic MPLS on the PEs:
# Configure PE 1.
