If you want the kernel to do the forwarding (mrd6 does it all in user- space I think), check http://clarinet.u-strasbg.fr/~hoerdt/linux_ipv6_mforwarding/ According to the web page, this code is now in the USAGI kernels. AFAIK there is no special support for scoping. But I think for PIM the issue is mainly to check scoping in PIM joins, and possibly also which addresses to accept PIM registers from (so that someone outside can't send registers to a local group). So I suppose these checks would be in the PIM implementation. So then it should be done in mrd6, pim6sd or whatever you're using for the routing.
