That was it- A quick TAC case later (about 10 minutes turnaround from
problem submission to resolution- upgrade IOS or remove multicast from
bgp peer) and the problem is fixed. 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.)
