[Dev] "Tracking Objects" Modelling....

Following on from the key-chain modelling, we come to "tracking object" modelling.

VRRP and HSRP (12.4+) support the idea of tracking objects.

When declaring a failover protocol you normally tell the failover protocol to "track" another interface. Tracking Objects allow you to declare a more in-depth set of tracking rules at the global configuration level and then just tell the failover protocol to track the object.

For example.

Track 101 interface FastEthernet1/1 ip routing
Track 102 interface FastEthernet1/2 line-protocol
Track 103 ip route 10.100.10.0 255.255.255.0 metric threshold

These can then be used by both HSRP and VRRP objects on many interfaces.

I'd like to declare them somewhere like <services> as they are used by many things under <trackingObjects>.

Does anyone have a better idea?

JB.
