3.4.3 Configuring Extranet

I. Network requirements
Both Company A and Company B locate their headquarters in City C. They are
interconnected with VPNs and own VPN1 and VPN2 respectively.
MPLS provides VPN function. There are some shared resources at the City C for two
VPNs. All VPN subscribers can access the shared resources, but VPN subscribers in
City A and City B cannot access each other.
The two companies cannot use identical IP addresses, for they share the same
VPN-instance at PE2.
