OSPF on Bay & Cisco....

[Nigel Taylor]

Folks,             I've got a question that involves using OSPF between a Bay/Nortel 5000BH and Cisco 7513.   Here's the topology..   7513 -----Ethernet-----Cat5k/LEC/ATM PVC-------- ATM Cloud  ----------- 2924 ATM LEC PVC/Ethernet --------- 5000BH     Basic picture..  Through the ATM cloud a PVC(point-to-point) is made from the Cat5k to the 2924. The routers see each other fine and I'm able to ping.  In running OSPF between the 2 points, I've had to go with using network statements instead of redistributing because Bay's implementation of OSPF only allows for 1 instance of OSPF and as well does not make use of process id's.  I'm able to pass the default route to the 5000, however the when looking at my neighbor state it goes from 2-way to full and back.  Now, I've looked into the hello interval and dead timers values and my thinking tells me that by establishing a full state that the values match on both ends.  In saying so even when my neighbor state is full, I'm having problems reaching a address that are NATed on the inside of the 5000BH.  Again my thinking had me looking at the "NAT configuration" but when a place a static route in the 5000BH everything works fine..?    thoughts.. anyone......   Until then it's "Debug time".....   TIA   Nigel
