Enhancing mtrace to detect failure in multicast diverse paths

摘要

In one embodiment, a network device may receive an mtrace query, where the mtrace query identifies two or more multicast routing paths. The network device may generate two or more mtrace requests using at least a portion of information obtained from the mtrace query such that each of the two or more mtrace requests identifies a different one of the two or more multicast routing paths. The network device may send each of the two or more mtrace requests via a different one of the two or more multicast routing paths. The network device may then receive at least one response including information pertaining to the two or more multicast routing paths.

1. An apparatus, comprising:
a processor; and a memory, at least one of the processor or the memory being adapted for:
receiving, by a network device at a merge point, an mtrace query that identifies two or more multicast routing paths from a source, wherein the two or more multicast routing paths converge at the merge point;generating, by the network device, two or more mtrace requests using at least a portion of information obtained from the mtrace query such that each of the two or more mtrace requests identifies a different one of the two or more multicast routing paths;forwarding, by the network device, each of the two or more mtrace requests via a different one of the two or more multicast routing paths towards a multicast router associated with the source; andreceiving, by the network device, at least one response originating from the multicast router, the at least one response comprising information pertaining to the two or more multicast routing paths.
