System: NetBSD vader.runit.sintef.no 1.3.1 NetBSD 1.3.1 (VADER) #17: Thu Mar 19 16:03:58 MET 1998 root@vader.runit.sintef.no:/usr/src/sys/arch/i386/compile/VADER i386


>Description:
	mtrace as in 1.3.1 (and NetBSD-current) does not know about the
	new protocol and error codes defined in the current multicast
	traceroute internet draft (draft-ietf-idmr-traceroute-ipm-02.txt).
	It additionally does not know the PIM/BGP4+ protocol code which
	apparently is in use, as shown below.

>How-To-Repeat:
	Inspect the following output:
