A method and apparatus for process sync restart is described. A computer implemented method comprises receiving a first set of data from a network process, determining death of the network process, clearing the first set of data if a time period expires, and synchronizing the first set of data with a second set of data if the time period does not expire, the second set of data received from the network process after the network process restarts.

A method an apparatus for multiple contexts and layer 3 virtual private networks is described. A method comprises providing a layer 3 virtual private network (VPN) to a first customer; providing backbone access to a second customer; and maintaining on a single network element a first set of information for the first customer separately from a second set of information for the second customer.

A method and apparatus for managing an information routing information base is described. A method comprises managing a routing information base (RIB), the RIB including a first set of elements that indicate a set of destinations, a second set of elements that indicate a set of next hops, a third set of elements that indicate a set of interfaces, receiving a message that indicates a modification to a plurality of routes corresponding to a plurality of the first set of elements, and modifying a first relationship between one of the second set of elements and a first one of the third set of elements and a second relationship between the one of the second set of elements and a second one of the third set of elements in accordance with the message, the one of the second set of elements referenced by the plurality of the first set of elements.

A method and apparatus for selectively packet mirroring is described. A method in a network element comprises selectively mirroring packets, the packets being associated with a first virtual path, the first virtual path indicating a first physical path and a first virtual path identifier and the selectively mirrored packets forwarded in accordance with a second virtual path, said second virtual path indicating a second physical path and a second virtual path identifier.
