Hi!=0A=0AI need some help, I had working multicast IPv6 routing using freeb= sd 8.3 =A0but when i try to test it I failed. my topology is like this with= freebsd as router and xp as server and client :=0A=0AXP1<---2001:abcd:10::= /64--->FBSD1<---2001:abcd:20::/64--->FBSD2<---2001:abcd:30::/64--->XP2=0A= =0Athis is my step to make the multicast routing:=0A=0A=091. i had re-compi= le my kernel with optionsMROUTING.=0A=092. i install the mcast-toolpackage.= =0A=093. i configure IPv6 static routing in rc.conf=0A=094. i also configur= e this in rc.conf=0A=09* mroute6d_enable=3D"YES"=0A=09* mroute6d_program=3D= "/usr/local/sbin/pim6sd=0Ai confused=A0where can i find pim6sd.conf, so i j= ust copied pim6sd.conf.example and rename it then i edit it, do i right?=0A= this my pim6sd.conf configuration on FBSD1:=0A=0Aphyint em0:=0Aphyint em1;= =0Aphyint em2;=0Astatic rp ff0e::123/128 2001:abcd:20::1;=0A=0Aaddress 2001= :abcd:20::1 is interface em0 on FBSD1 and its linked with interface em0 on = FBSD2.=0Athe configuration for FBSD2 is similiar to FBSD1.=0Ai do streaming= with vlc to test the connection but failed.=0Ai also set ttl >1 but still = failed.
