OSPF ISDN

[miguelchora]

Hi,

I'm implementing the following scenario:

I've got 3 routers (r1,r2 an r3), r1 are connected to V35 leased line to r2 and r2 have a ISDN backup line r1 when that leased line fails. There also r3 that is connected to r2 to another V35 leased line, but when the ISDN line comes up, all the comunications between r1 and r3 are gone.

I'm using ospf ... I've tried everything.

Thanks for your help
Cheers
Miguel

Can you post the configs for the three routers?
