Hi guys-
The ASN-10886 is registered to UMD, but it represents the MAX Layer 3
network. NSF peers with MAX (at UMD), and MAX peers with Abilene (NYCM) and
VBNS (PYM).
I am not multicast peering with VBNS, just with Abilene. It is conceivable
this could be contributing to some of the difficulties. NSF is msdp peering
with WASH-CORE (max), and MBGP/PIM-SM with WASH-AG (the max border).
I can bring up the VBNS peering relatively easily. I'll contact VBNS
tuesday morning to chase this and see if Kevin or Zaid can sanity check my
mcast configs.
BTW- Please check your email address for me- it should be
jerrys at max.gigapop.net
Thanks
Jerry
