Hi,
I know we visited this before but I still have the problem. I have attached a diagram to illustrate my dilemme.
Basically we run OSPF between between Sites A and B. At Site A I have injected a static route from Router 1 to 2. The reason for this that the ISDN backup is on router 2.
What's happening at the moment is the ISDN backup keeps initialing for no apparent reason. Could it be OSPF related?
Check attachments for errors and diagram.
Config on Router 1:
ip route <network B> 255.255.255.0 <router1 IP> 240 name isdn-backup
On Router 2 I have a dialer configured and a route statement pointing to that dialer.
Here is config:
ip route <network B> 255.255.255.0 Dialer3 240 name isdn-backup
Config on Router 2
