Thanks. But I need to get tunnel working. Can you suggest some other way of getting a multicast tunnel work. The assumption is that there is a unicast cloud in between two mbone networks. So we need to forward the multicast traffic over the unicast tunnel. Application is for video transmission. thanks, Nazeem On Thu, Jan 28, 2010 at 3:19 PM, Bruce Simpson wrote: > Tunnel support for MROUTING was removed several FreeBSD releases ago. > > We followed OpenBSD with this change because DVMRP's older, naive IP-in-IP > encapsulation mechanism doesn't offer any benefit, and can't be > administered.
