Re: New Internet Draft on automatic (end-user) tunneling for SSM

[jhall@UU.NET (Jeremy Hall)]

Hi,

Am I to understand this right, multicast routers are suppost to snoop ALL
UDP traffic that matches this port and process switch it?

Are you making the assumption that

1: the source is reachable from the receiver unicastly

2: somewhere unicast and multicast align

3: unicast and multicast topologies are congruent
