I currently have a network ring comprised of 9 Catalyst 3560's. they currently do spanning tree, and I place a "dead" link across my slowest link so that traffic all flows one direction until the ring is broke. I want to migrate away from spanning tree, and use OSPF. I already have OSPF in place, but traffic flows in all directions around the ring. I realize that is the nature of OSPF, but is there some way I can make the link i don't want any traffic on look less attractive to OSPF so that it doesnt send any traffic down it at all unless another link is broke just like spanning tree? I have tried messing with priorities and path costs with no avail. is there someway i can make OSPF think there is more than 1 hop on a particular link?
