[AG-TECH] Multicast to Alaska

[Bob Huebert]

You are correct in seeing a path to/from ARSC/ANL. Problem is, as I'm 
told, is that this is strictly a unicast route - for now. There is a 
plan to implement multicast over this route sometime shortly into the 
new year.

Also, the 137.229 domain you traced to was swapped to 199.165 for 
ARSC this past August.

Thanks

Bob
