You can configure up to three next hops for each static route in one of the following manners:
Enter all of the next hops using a single ip route command. To add a new next hop to an existing static route, enter the new next hop individually, as in the following option.
Enter each next hop individually with its own ip route command
Note:
If you apply tracking to a static route, you can only configure one next hop for the route.
Metrics are used to choose between routes of the same protocol. Preferences are used to choose between routes of different protocols.
