track command

[bellocarico]

I've been playing with the object tracking. Is there any way to use a negative condition? (e.g. Install my static route when a specific interface goes down)

in the following example I install a default route only if interface 1/0 is up/up, but what about if I want to install the default route ONLY if serial 1/0 is down instead?

Router(config)#track 55 interface serial 1/0 line-protocol

Router(config)#ip route 0.0.0.0 0.0.0.0 serial 1/1 track 55

Found :-)

I had to create a parent object (boolean)

where I specify a not condition:

track 10 interface Serial1/0 line-protocol

track 55 list boolean and

object 10 not

ip route 0.0.0.0 0.0.0.0 serial 1/1 track 55
