I have 6 towers forming a closed ring. At each tower there are three RB532, one for routing and two dedicated to bridging the links from tower to tower, set up on /29 networks. I have one entry point and have OSPF running in NBMA mode. I would like to inject another point of bandwidth at the other end of the ring. I have tried changing the cost of two of the links, basically separating the network in two based on cost; but with two routers injecting default routes things are not working correctly. Anybody have any tips on how to set up OSPF to get this working?
Thanks,
Mike
