Folks, application folks in my company complain that multicast traffic for a group 239.254.13.31 does not work. They say that traffic for group 239.254.13.32 works OK. I do mtrace from Layer 3 switch and the difference I notice is that the last path (-4 10.12.17.3) is not listed for the 239.254.13.31. Can someone confirm what I can infer from this mtrace output?
switchL3#mtrace 10.12.17.3 10.12.49.15 239.254.13.32
