Routing Information Protocol Version 2.0

1 Routing Information Protocol Version 2.0 RIPv2 Objective: onfigure RIPv2 between R1 and R2 to obtain connectivity between Networks Directions onfigure R1's interface F0/0 with the IP address /16 onfigure R2's interface F0/0 with the IP address /16 onfigure R1's interface F0/1 with the IP address /8 onfigure R2's interface F0/1 with the IP address /8 onfigure RIP version 1 on R1 and R2 All active interfaces on R1 and R2 should participate in RIPv1 routing Ask Yourself What is the difference between RIPv1 and RIPv2? How does RIPv2 transmit updates? How does RIPv2 deal with fixed-length subnetted networks? How does RIPv2 deal with variable-length subnetted networks?
