I'm having multicast issues at the Argonne Lobby. Outgoing traffic (from
Utah) is fine as confirmed by LSU. But I'm not seeing any incoming
traffic, other than my own. Our network staff looked into it and here's
there current consensus:
Joe and I confirmed that our path to 140.221.11.45 at Argonne
comes over I2.
We used the Internet2 router proxy
http://routerproxy.grnoc.iu.edu/internet2/
<http://routerproxy.grnoc.iu.edu/internet2/> to look at the multicast
routes on I2's routers. Our I2 router (SALT) didn't know those groups,
and neither did Chicago (CHIC), where Argonne connects.
It looks like something is unhappy at Argonne or between them
and I2. Joe talked to Jimmy and he will let the Argonne folks know what
we've found.
So, could someone verify this?
Thanks,
Jimmy
