Hi,
I get a panic when trying to use net/pim6dd on -current. I have tried a
plain GENERIC kernel and one with options MROUTING and PIM defined. I
can reproduce it on a test box with only one interface with
ipv6_enable="YES" in rc.conf and then on the commandline do this:
ifconfig gif0 create
ifconfig gif0 tunnel <my_ip_address> <a_ip_address_on_another_subnet>
ifconfig gif0 up
pim6dd
