I removed multicast since it was not required on this peer, and will schedule the IOS upgrade during a more friendly maintenance window. GBLX, however, has not returned my call since I opened a high priority, customer down ticket about 1.5 hours ago. Like all other support calls to their NOC, this seems to have disappeared into nevernever land. I love the GBLX network when it works, but god help you if you ever need to talk to a clueful NOC person to fix a problem (especially after hours.) bill
