One embodiment of the present invention provides a switch. The switch includes a processor, a storage device, a multicast management module, and a graceful recovery module. The multicast management module participates in a multicast tree of a multicast group. The graceful recovery module determines a recovery event and constructs a message indicating the recovery event for a second switch. The switch and the second switch belong to a first virtual local area network (VLAN). The graceful recovery module then identifies a completion notification message from the second switch indicating a completion of replaying multicast information stored in the second switch and includes multicast information received from the second switch in a local multicast database.

Techniques for efficiently updating routing information in a network device such as a router. According to an embodiment of the present invention, the routing information is updated upon creation or deletion of an overlay tunnel without the network device having to regenerate a Shortest Path Tree (SPT) by performing full Shortest Path First (SPF) processing.

Techniques for synchronizing data object instances between applications/processes in an efficient manner. In one set of embodiments, the techniques described herein can be implemented in one or more network routers to synchronize data between a process running on an active management processor and a process running on a standby management processor, thereby facilitating features such as non-stop routing (NSR).
