Transmitting IP datagrams through X.25 PVCs
Network requirements
As shown in Figure 139,
• The PVC range that the packet network allows is [1, 8]. The PVC numbers assigned to Router A
and Router B are 3 and 4.
• The IP addresses of LAN 1 and LAN 2 are 202.38.165.0/24 and 196.25.231.0/24.
Exchange route information between LAN 1 and LAN 2 by using RIP, so that Host A and Host B can
exchange information without any static route.
