I have successfully configured PBR on the 2621 XM router. The purpose is to route mail traffic to the LL interface, and all other traffic to the frame realy interface. It all works and looks ok.
The mail ISP supports isdn connections as well, so I want to configure my serial (LL) interface to switch to the BRI when the link goes down.
The problem is that I can't properly set-up the PBR. I tried with this:
route-map mail-ISP permit
match ip address 111
set default interface Serial0/0 Dialer1
but this wont' work. When the s0/0 is down, nothing happens. I wonder if this is the right configuration at all? I didn't find what this command truly do:
set default interface IF1 IF2...
What is the proper usage? Will it ever go to IF2?
Or I am on the wrong track in the first place.. I even tried with "backup interface" command, but again with no luck. When s0/0 goes down, dialer1 goes up, but there are no placed active calls(!) Again, no calls, but dialer1 is up... Strange...
Can someone please give me a hint. I can post more details/configs/debugs if needed.
Thanks in advance.
