mtrace PIM response

hhorton · ‎12-18-2019

I did an mtrace and got "PIM Wrong interface [default]" on the last hop. I can't find any documentation on what this means or why it occurs. Anyone got info?

RTE3850#mtrace 165.199.4.21 10.82.210.53 234.5.5.188
Type escape sequence to abort.

Hello,

I couldn't find anything on this message either. Can you reach the multicast destination at all ?

Yes I can reach the destination. Interesting I've used the same CLI command on several of my routers and it's "wrong interface" is a common response. All but one of my routers have dual (redundant paths) into the MAN. The only router I tested that didn't get this error does not have the redundant path.
