Names

Next Hop Router

The closest routing device.

Metric

The number hops to get to the destination.

Fallback metric

IP redundancy or fallback IP routes. A fallback route is a second static route with the same destination and netmask of an existing route but with a different nexthop destination. The redundant or fallback route is used when the original nexthop destination is unavailable. The fallback route continues to be used until the revertive period expires. At that time, traffic switches back to the primary route.

Ping interval (ms)

A ping interval is used to determine route availability. The active nexthop router is pinged once during each ping interval. The ping-interval is specified in milliseconds and has a minimum value of 500 milliseconds or 1/2 second.

Max number ping fail

If the number of ping failures to the current nexthop destination exceed the ping-fail-max setting, the current nexthop destination is replaced in the routing table with the fallback nexthop destination.The system begins pinging the new nexthop router and monitoring the number of ping failures. The revertive period is set by the system based on a multiple of the ping interval and retry count.
