This is working as designed. It's defined as a boolean AND operation. That means for Track 3 to be up, Track 1 AND Track 2 must be up. Consider UP to be True (1) and DOWN to be False (0). 0 && 0 = 0 0 && 1 = 0 1 && 0 = 0 1 && 1 = 1 The only way a boolean AND object will be up will be if all elements of the track list below it are also up. This is shown in the help for the command: R4(config)#track 1 list bool ? and Boolean AND operation on list or Boolean OR operation on list Try an "or" list if you want the boolean object to be up if ANY of the listed objects are up.
