XORP itself provides PIM-SM using IPv4 or IPv6. But obviously you
need to run XORP on an OS with a forwarding path that has appropriate
support.
If you need PIM-SM using IPv6, right now the best bet is probably to
use FreeBSD 4.9 (or FreeBSD 5.x, but 4.9 is probably preferable). The
kernel changes needed for efficient PIM usage are already included in
FreeBSD. Probably best to wait for the XORP 1.0 release due out
shortly though, or at least run the latest CVS snapshot.
The remaining issue would be if you need to use this as an SSM edge
router, because then you'll need IGMPv3/MLDv2 router support to allow
local hosts to join. Currently we only have IGMPv2 and MLDv1 router
support in XORP. IGMPv3/MLDv2 is on the roadmap for later this year.
Pavlin Radoslavov is the XORP multicast guru. He'll no doubt correct
me if I got anything wrong.
Cheers,
Mark
