OK the below script watches errors on a path. When it crosses the thresshold it sends a trap and changed the netmask on the path to prevent the route to the far node being used. on so this network is built as two seperate networks. For this lets call them network "A" and "B". the two networks do not touch. Even the OAM network to the router is on seperate vlans. so the chalange is to add inteligence to the script to not run if the router on the "B" network with this same script has dissabled the route so we do not end up with the "A" & "B" network isolated at the same time.
Yes I can think of many other ways to do this, but this is what is in place. So how would I set a varible or some flag that I could check to make sure an event has not taken the other path down? Checking for a file or something on a remote box is my first thought. Anyway I am tossing this out to see what some fresh minds might come up with.
