A colleague is trying to work out how to stop an ISDN router dialling out on bootup. We do have a solution but unfortunately we have to stick with an older 1721 running IOS 12.3.X and the way we found isn't supported in the software. Additionally, the router hasn't the memory to run the 12.4.X software that has this feature.
The way we found was to track the line protocol on Vlan 1 as follows:
track 10 interface Vlan1 line-protocol delay up 120
ip route 0.0.0.0 0.0.0.0 Dialer10 250 name delayed-floating-static track 10
Has anyone managed to achieve this by some other method ?
Regards
