We have a network that uses ospf. We have two central sites that our site routers dial in thru ISDN for backup. I was wondering how many of you are running ospf over isdn (used as backup). How would I go about setting up ospf to run over isdn to work well. We are currently using floating static routes and use RIP ver 2 to redistrubute back to ospf when the rip routes show up (when primary circuit is down). I was wondering if there is a way to set this up using ospf instead of RIP. a while back we were using EIGRP and things were working great, ( isdn would kick in and routes would be there instantly, possibly becuase of EIGRP sucessor and feasable sucessor deal) but due to the carrier we were forced into OSPF.
Let me know if you guys have any ideas or config expamples or web pages that would address my issue.
Big thank you for all that respond.
