This means that there is never any ambiguity between a congested unresponsive link and a host on an unreachable network. One way of doing this is with an SNMP ping (eg check sysUpTime) to a router on the subnet of interest. (The actual application is determining if user subnets are reachable when there is a routing protocol on each of the leaf [user subnet] routers tunnelled through an MPLS transport. All sorts of wierd stuff can happen. We use a routing protocol even on the single exit leaf nodes because we cannot trust the provider [eg the only routing protocol they provide is RIP ...]).
