The availability of the far-end static route is monitored through periodic polling. The polling
period is configured. If the poll fails a specified number of sequential polls, the static route is
marked as inactive.
Either ICMP ping or unicast ARP mechanism can be used to test the connectivity. ICMP
ping is preferred.
If the connectivity check fails and the static route is deactivated, the 7705 SAR router will
continue to send polls and reactivate any routes that are restored.
