As for bridge,u are right. some bridge are not supporting multicast will do broadcast. even in broadcast i still can recv traffic. --- Bruce M Simpson wrote: > On Wed, Oct 20, 2004 at 07:53:28AM -0700, Yong Chu Eu (杨子佑) wrote: > > i am try to stream from freeBSD multicast router(without kame but with > > pim6sd,route6d)to MN throught Access Point which are redhat.
