After the configuration, the Spoke-CEs can ping each other. Run the tracert command, and you
can see that the traffic between the Spoke-CEs is forwarded through the Hub-CE. You can also
deduce the number of forwarding devices between the Spoke-CEs based on the TTL in the ping
result.
Take the display on Spoke-CE1 as an example.

Run the display bgp ipv6 routing-table command on the Spoke-CE, and you can see the default
route advertised by BGP on the peer Spoke-PE. Run the display ipv6 routing-table command,
and you can see the default route whose next hop is the peer Spoke-PE.
Take the display on Spoke-CE1 as an example.
