Looking at Figure 10, what would be the RID for this router?

A. 10.0.0.1

B. 172.16.4.2

C. 192.168.0.0

D. 10.0.0.3

E. There is no way to tell.

Answer 1

D is correct. The RID was explicitly configured with the Router1(router-config)#router-id 10.0.0.3 command.

A, B, C, and E are incorrect. A is incorrect because it would have been the RID if the router-id 10.0.0.3 command hadn’t been entered. B is incorrect because 172.16.4.2 is the next-hop address for our default route. C is incorrect because it is one of the networks to be included in our OSPF network. Eis incorrect because this choice is not valid.
