# 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.
