This topic is to discuss the following lesson:
I think there is a mistake in the second line in
R1(config-router)#network 172.16.0.0 R1(config-router)#network 172.16.12.0
It should be “network 192.168.12.0” instead right ?
I was thinking in order to fix this sub-optimal routing problem of Router R2, why not use the same summarization for the Gi0/2 on R1?
Please let me know if this would be a solution to this problem.
Your solution would work. What you propose doing would be essentially to suppress all specific /24 routes, and only advertise the /16 summary both to R3 and R2. In this case, since the prefix lengths are the same, R2 would fall back using the lowest metric to get to the summary, which for RIP would simply be hop count. R2 would choose the direct connection to R1.
You are correct. I will request that this get corrected. Thanks for point this out.
