Abstract
The present disclosure relates a system and a method of identifying network faults residing in an underlay network. A network device initiating fault analysis sends a query message through a tunnel interface present in an overlay network configured over an underlay network. While an upstream interface is a network tunnel having a first end and a second end, a unicast path from the first end to the second end of the network tunnel is traced using a network route analysis function. Reachability of a destination device present on the second end of the network tunnel is identified. An output of the network route analysis function is appended with an output of a multicast network connectivity determining function to produce an appended result that is shared with the network device initiating fault analysis.
