All, So i have this network, and i am thinking i have a loop. I'm just not sure where or how. And i think it started happening after i created vlan interfaces in all vlans on all switches. So Cat1 is having vlan14,vlan567 and vlan69 interfaces and all the other switches in similar.
They are NM16ESW cards, but IEEE stp is running so a Layer2 loop should be out of the question. Could i still have a routing loop? I am running OSPF in one giant area 0. How would i go about solving it? I can't use split horizon as OSPF doesn't use that. Should i artificially set routes such that they get a lower metric and manipulate things like that? I attached a small picture to clarify (this is taken from the Security lab Day4 VoD btw). Mind you, it might be something different entirely although i don't think so. But it's probably going to be something very stupid. And yes, i probably don't understand switching very well yet :-) Alef
