Section 1.1 In the Yellow service provider network, the IPv4 topology must be different from the topology. Enable IS-IS in this network to support this requirement. Use the diagrams provided (diagram 1, 2, and 3).
Key-
Y-ISP modify IS-IS ipv4 & ipv6 topology.
Tips-
1.This section Yellow collour is config. Other is preconfig.
2.Y-P1, Y = Yellow.
