Claim 8:
9. An end-point network device, comprising:
a tunnel state database specifying a path and a second path between the end-point network device and a target network device;
a local interface to which the path is connected;
network device hardware configured to transmit packets to the target network device over the path;
a processor; and
a virtual tunnel state agent comprising instructions which, when executed by the processor, causes the processor to:
initiate monitoring of the path;
detect, based on the monitoring of the path, that at least a portion of the path, beyond the local interface, has failed; and
update, based on detecting that at least the portion of the path has failed, the network device hardware to redirect packets from the end-point network device to the target network device using the second path.
