Hello;

I am staying at Carmen Hall at Columbia U for the I2 working group
meeting. I can see the SAP announcements from OnTheI/AmericaFreeTV in
Virginia, but I cannot get any actual multicasts from there - although
I get KWAK from Eugene just fine.

Something may be messed up with the routing as from Virginia

multicasttech-1> show ip bgp 160.39.137.191

Can anyone shed any light on this ? I would like to do some tests from here
if I can.

(BTW - I thought L3 peered with Abilene - why is the unicast going through
Broadwing ?)

Regards
Marshall
