Configuring Mpls L3Vpn Inter-As Option A - HP FlexNetwork 10500 Series Configuration Manual

# Execute the display bgp peer vpnv4 command on the PEs to verify that a BGP peer
relationship in Established state has been established between the PEs. (Details not shown.)
Verifying the configuration
# Execute the display ip routing-table vpn-instance command on the PEs to display the routes to
the CEs. This example uses Spoke-PE 1 to verify that the next hop of the route from a Spoke-PE to
its connected Spoke-CE is Hub-PE.

# Verify that Spoke-CE 1 and Spoke-CE 2 can ping each other. The TTL value indicates that traffic
from Spoke-CE 1 to Spoke-CE 2 passes six hops (255-250+1) and is forwarded through Hub-CE.
This example uses Spoke-CE 1 to verify their connectivity.

Configuring MPLS L3VPN inter-AS option A

Network requirements
CE 1 and CE 2 belong to the same VPN. CE 1 accesses the network through PE 1 in AS 100, and
CE 2 accesses the network through PE 2 in AS 200.
Configure MPLS L3VPN inter-AS option A, and use the VRF-to-VRF method to manage VPN routes.
Run OSPF on the MPLS backbone in each AS.
