Simpler solution... Just set the P flag and use your unicast prefix as part of the group ID. For example, if your unicast prefix is 2001:db8:f00d::/48, you could use: ff4e:2001:db8:f00d::<group number> Where <group number> is any number of your choosing up to 64 bits, but recommended to be ≤32 bits. Make sense? Owen On May 3, 2012, at 1:00 PM, Greg Shepherd wrote:
Sure, but GLOP predated SSM, and was really only an interim fix for the presumed need of mcast address assignments. GLOP only gives you a /24 for each ASN where SSM gives you a /8 for every unique unicast address you have along with vastly superior security and network simplicity.

All inter domain mcast uses source trees only, so just use SSM and you don't need address assignments.
