Label distribution protocol label filtering

摘要

In one embodiment, a device of a particular non-backbone routing domain in a computer network determines whether each of one or more routes is reachable within the particular non-backbone domain. The device may then generate a filtered set of label mappings having only those of the one or more routes reachable within the particular non-backbone domain. Accordingly, the device may advertise label mappings only of the filtered set to one or more neighboring devices.
