We, like others tried to implement OSPF because it was supposed to be the holy grail of internal routing as far as 3Com was concerned. I had high hopes for it because we have occasional lapses in RIP2 propogation to the Cisco router. By that I mean occasionally the rip routes for a given chassis just disappear, then reappear after about 20 to 30 minutes. I had to place static routes to each chassis defining the space containing the assigned ip address pool to get consistent access for the majority of our clients. Dedicated ip clients still occasionally experienced the problem until I put a static route to one of the Arcs for each client. If the RIP was working it seemed to overide the static route, if not the traffic bounced of the Arc on to the correct Arc in most cases. 3Com was of abosolutely no help on this matter while we were under contract, hence no current contract. I never could get OSPF to work but that is probably because I have never worked with it before and the docs are a bit thin on application. Has anyone else experienced RIP problems? I thought it might be someone stuffing the Cisco with bad routes so I moved to authenticated RIP with no change in behaviour. I haven't removed the static routes since we got to 4.2.32-1 to see if the problem is still there.
