Re: Native Multicast (Was: Re: Contest! )

My understanding is that there are sync problems with deploying mcast
native. Most notedly when BGP uses memory and cpu and then
pruning/mrouting also wishes to use the cpu. I haven't personally
experimented with this, but have heard interesting stories about egress
problems near borders.
