<DIV><SPAN class=755252218-17042008><FONT face=Arial>I'm having multicast issues
at the Argonne Lobby. Outgoing traffic (from Utah) is fine as confirmed by LSU.

<P>Joe and I confirmed that our path to 140.221.11.45 at Argonne comes over
I2.</P>
<P>We used the Internet2 router proxy</P>
<P><A href="http://routerproxy.grnoc.iu.edu/internet2/"><U><FONT
color=#0000ff>http://routerproxy.grnoc.iu.edu/internet2/</U></FONT></A> 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.</P>
<P>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.</P></SPAN></DIV></BLOCKQUOTE>
