Abstract: The problem of being unable to run microBFD using an IPv6 address over any member links of a layer 2 LAG when the LAG is DOWN (and its IPv6 address becomes or is TENTATIVE), is solved by running DAD for the address configured for the microBFD once the individual link is in DISTRIBUTING or STANDBY state and triggering (or starting) microBFD once the DAD for that address completes successfully. Further, member links of the LAG may be permitted to continue running microBFD even if the LAG interface is DOWN and even if some other member links (but not all member links) of the LAG are DOWN.

Abstract: The disclosed system may include (1) a cache module, stored in memory, that stores a neighbor cache entry that specifies whether a neighbor of a network node is reachable according to a detection mechanism, (2) a timeout module, stored in memory, that specifies a timing interval in which to select a reachable time threshold, (3) a reception module, stored in memory, that receives event information about whether the neighbor is active, (4) a biasing module, stored in memory, that biases, based on the received event information about whether the neighbor is active, a selection of the reachable time threshold within the timing interval, and (5) a determination module, stored in memory, that determines whether the neighbor is reachable based at least in part on a determination of whether the selected reachable time threshold has been satisfied. Various other systems and methods are also disclosed.

Abstract: A device may activate a layer 3 interface of the device based on activation of a first layer 2 interface associated with the layer 3 interface. The device may detect activation of a second layer 2 interface, associated with the layer 3 interface, after activating the layer 3 interface. The device may activate a filter to prevent transfer of network traffic via the second layer 2 interface based on detecting activation of the second layer 2 interface. The device may perform duplicate address detection, in association with the second layer 2 interface, for a layer 3 network address assigned to the device. The device may determine whether the layer 3 network address is a duplicate network address based on performing the duplicate address detection. The device may selectively maintain or deactivate the filter based on determining whether the layer 3 network address is a duplicate network address.
