Ok. NBMA networks are kind of tricky when it comes to OSPF, as they are not quite broadcast or point-to-point networks. Try some of these commands to troubleshoot the problem, as I've never done this exactly (I don't want to do OSPF on a WAN link like that), but I have the theory behind it. 1: On Older versions of IOS, you can use the following command under routerer ospf <number>: neighbor x.x.x.x [priority #] [poll-interval #] priority 0 = no DR, poll-interval is how many seconds between hellos 2: Under the sub interface, use this command: ip ospf network [broadcast | non-broadcast | point-to-multipoint] broadcast makes the WAN look like a LAN, but you'll have to worry about DRs and BDRs, so you'll need to use priority to make sure your DR is always seen. Non-broadcast is for Point-to-point links, and no DR is elected. Point-to-multipoint the "Cloud" becomes a single subnet for IP, no DRs necessary, but you get tons more LSAs than before with more information. > OSPF is active on the MAX when checking it from the command prompt.

It probably needs to think of the link as point-to-point or point-to-multipoint for OSPF to work properly. Also, the area 0.0.0.0 will give you trouble if you decide to start adding other areas. I suggest you set it to area 0 instead of 0.0.0.0 (0.0.0.0 can be used as another area seperate of area 0, but it is my understanding that it is not the same as area 0). > I have OSPF configured on the stand alone MAX on the Ethernet side as well > as the "Connection" side. > > Thinking this might be an IOS concern I have also tried to get a different > MAX to talk to the 2514 (IOS 11.2) with the same results. > > Curious if anyone else has this working, any input greatly appreciated. > > Regards, > -Bill Hamel Send me a copy of your cisco config off list and I can take a look at it for you.
