Hi all, Doing some reading on EIGRP today and came across a note about how two EIGRP peers can (unlike OSPF) form a neighbor adjacency even with mismatched IP subnet masks, on the condition that both peers agree that the other is within their understanding of the subnet definition. So the example was that two routers addressed with 10.1.1.1/24 and 10.1.1.2/30, respectively, would neighbor up.
OK, fine, so this leads to my question: On the lab let's say I had a task to enable EIGRP for network 10.1.1.0 (mask unspecified...) on the two routers with the IP addresses in my example above. Simply configuring: router eigrp 1 no auto network 10.1.1.x 0.0.0.0 Would work, and the neighbor adjacency should form. ASSUMING for the moment that no subsequent task would require me to fix the mask mismatch, should I fix it? I realize there could be other implicit requirements in this case that could force me to fix the mask, but the general question stands: should I fix something that is "wrong", but works? Thanks!
