I need to implement a static backup route and would like to know 2 things:
1. If I create 2 routes and it makes it through all routers on the primary route BUT the host is down, I presume that it was successful and it will not try the backup route. Am I correct?
ip route 10.0.0.0 255.255.255.0 172.20.0.1
ip route 10.0.0.0 255.255.255.0 172.30.0.1
2. I have seen reference to AD and Metric. I understand the lower AD sets the primary route, whereas higher AD is backup route. Is the 'Metric' a way of setting the primary/backup routes as AD does? Example if route 1 has a metric 1 will it always use this first as opposed to metric 2 for the backup route?
