I. Networking Requirement
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.

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.
