As shown in the following diagram, a company makes use of MPLS L3VPN 
provided by its service provider to provide the VPN services. 3Com Routers are 
taken to work as PEs and CEs. Assume that the interface Serial0/0/0 connecting 
PE1 to CE1 is bound with VPN1, Serial1/0/0 connecting PE2 to CE2 to VPN2, and a 
host PC1 at 100.1.1.2 under CE1 can access multiple VPNs, or rather, VPN2 in this 
particular scenario.
