OSPF enviroment with Backup on ISDN BRI

I have a network with 20 OSPF routers connected with Serial lines.

Now I must configure ISDN Backup lines and I need to use OSPF on all ISDN backup lines !!!

While soluction I can use ????

I have read that snapshot routing is supported by RIP, IGRP but NO OSPF.

Thank's and ..ciao

Re: OSPF enviroment with Backup on ISDN BRI

You should probably check out this document for scaling OSPF with ISDN backup: http://www.cisco.com/en/US/customer/tech/tk648/tk365/technologies_tech_note09186a0080094052.shtml

Also, another OSPF feature to look into is enabled by the "ip ospf demand-circuit" command.
