Configure Virtual Circuit I. Networking Requirement

Range	The link layer protocol of router's interface Serial0 is X.25l, with the virtual circuit
	range: permanent virtual circuit section [1, 8], incoming-only channel section [9,
	16], two-way channel section [17, 1024], and the outgoing-only channel section is
	disabled.

Transmit IP Datagram via X.25 PVC

I. Networking Requirement

In the following diagram, the permanent virtual circuit section allowed by the packet network is [1,8], the PVC numbers assigned to Router A and Router B are 3 and 4 respectively. The IP network addresses of Ethernet A and B are 202.38.165.0 and 196.25.231.0 respectively. It is required to exchange routing information between Ethernet A and B with RIP routing protocol, so that PC A and PC B can exchange information without adding static route.
