# Issue the display ip routing-table command on the CEs, you can see that the cost of the OSPF
route to the peer CE is now 10 (the cost configured for the sham link), and that the next hop is now
the VLAN interface 11 connected to the PE. This means that VPN traffic to the peer is forwarded
over the backbone. Take CE 1 as an example:
[CE1] display ip routing-table
