There are likely several answers to that, all dependant on your topology and protocol use. But, a good place to start would be BFD (bidirectional forwarding detection). Juniper has decent support for it working with other protocols (OSPF, ISIS, BGP, RIP), notifying them that something may be wrong, allowing them to then make a decision (support may differ from protocol to protocol). That may be a good start point.
