https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D265857 --- Comment #24 from Zhenlei Huang <zlei.huang@gmail.com> --- I suspect some multicast packets are discarded. Can you do a tcpdump capture on D while ping6 A -> B, and ping6 A -> D ? Make sure clear neighbor cache on both side before every ping. tcpdump listerning on D: ``` # tcpdump -nvei mce0 ``` For A -> B: ``` # ndp -c # on B ``` ``` # ndp -c # on A # ping6 -c1 <PREFIX>::12 # ndp -na ``` For A -> D: ``` # ndp -c # on D ``` ``` # ndp -c # on A # ping6 -c1 <PREFIX>::10 # ndp -na ``` You can omit the <PREFIX> . Or send the pcap privately to my FreeBSD email zlei@FreeBSD.org --=20 You are receiving this mail because: You are the assignee for the bug.=
