I have situations where a router has two uplinks: a main link and a backup link
As wil any backup option, it is only worth having one if you know it willl work when you actually need it
So I have VoIP travelling through the backup link so as to ensure that this one is always up and ready
I want to setup a queue tree for this router but I'm not sure how to go about this
Should I create my queue tree with upload and download structures that are attached to the global interface or should I have two separate U/D tree structures, one for the main uplink and another for the backup link ?
