ISDN backup for Frame Relay Network

What would be the best method to backup FR with ISDN. My scenario is the following: FR connection to all remote offices, using sub-interfaces, and OSPF protocol. I have read all the options but I still can't decide. Backup Interface or Dialer watcher? I also want to keep it simple yet effective. Thank you.

Re: ISDN backup for Frame Relay Network

Since I am not familiar with your network setup and any special requirements that you may have, I will refrain from recommending one particular method over another.

Check out this link

This gives an evaluation of all the methods available and their pros and cons. You should be able to decide after reading this document.

Hope this helps
