Group, In the lab again looking at a scenario. At first, I configured a transit link with a /24 mask. Later I thought - gee that's going to be a /29 or /30 in real life so I went to change it. However, the router wouldn't accept "network 200.1.1.0 0.0.0.7" under "router eigrp 10". It fails with the caret pointing at the first zero in the wildcard mask. doing a "?" after "network 200.1.1.0" just comes up with a <cr>. However, on CCO I see examples of both statements - some with the mask others without. Has the behavior of EIGRP changed lately even so that CCO has conflicting examples or am I missing some connection? All routers have ip classless and ip subnet-zero configured. By the way, my lab scenario has OSPF redistributing the EIGRP. Looking at an upstream routing table it shows the EIGRP network as a /29 even though there is no "mask" in the statement. So what am I missing?
