Help With RIP2 Question - Please help

kewlguyjason

Can someone please explain why network 10.0.0.0 would be the answer and not network 10.1.0.0?
I got this straight from one of the practice problems.

Imagine an internetwork that has a dozen interconnected routers. The IP addresses of all interfaces on all routers begin with 10.1. RIP Version 2 has been chosen as the routing protocol. What three commands must be configured on all routers to enable RIP V2 in this internetwork.

A. no version 1
B. router rip <-answer
C. router rip version 2
D. network 10.0.0.0 <-answer
E. network 10.1.0.0
F. version 2 <-answer

The answer book actually says network 10.1.0.0 won't be accepted for RIP configuration.

Thanks a bunch.

The command of "network 10.1.0.0" would be accepted by the router but because the network command is classful for rip (version 1 or 2) the router will change it to "network 10.0.0.0" in the configuration file. This is a case of one answer choice being slightly better than the other but they would both work.

BTW: I am assuming answer b should be "router rip" not "router ip"
