It is likely I will prototype the work in FreeBSD. It will probably not be released publicly. To prepare for this I have started cleaning up the MROUTING code; using more appropriate data structures, working on removal of the 32 vif limitation and other refinements, removal of legacy code which is no longer useful. I'd like to hear from anyone using multicast forwarding on FreeBSD who would be interested in testing these changes and suggesting other improvements.. They will most likely not make the 7.0 release but may appear in future versions. Code is not yet available as a patch set. I am working in the p4 branch bms_netdev. regards, BMS P.S. It would be good if there were a way of giving the general public read-only access to the p4 tree, this is becoming a blocking limitation of the tool for open development.
