Execute the display ip routing-table command on CE 1 and CE 2. The output shows that the
internal routes of the customer carrier network are present in the public network routing tables, but
the VPN routes that the customer carrier maintains are not. Take CE 1 as an example:
[CE1] display ip routing-table
Routing Tables: Public
Destinations : 16 Routes : 16
