Hi I'm doing a lab that ask to summarize three networks with the most efficient mask as possible.
I have : 6.6.160.0/30 6.6.160.4/30 6.6.160.8/30 Ok so a /28 would be too long because it would include a network I don't have 6.6.160.12/30. The good solution is to only aggregate 6.6.160.0/29 and leave alone 6.6.160.8/30. Problem is, the proposed solution said the longest mask is a /28... I'm pretty sure at 99% I can't advertise that mask, I would not in a production network. But a lab is a different beast. Did I miss something ? maybe I'm just tired and I don't see an obvious thing. Thanks
