Issuing the display ip routing-table command on CE 1 and CE 2, you should see that the internal
routes of the Level 2 carrier network are present in the public network routing tables, but the VPN routes
that the Level 2 carrier maintains are not. Takes CE 1 as an example:
[CE1] display ip routing-table
Routing Tables: Public
