All things related to multicast

[Tony Rimovsky <>]

I can't say that for certain, no.  

I do know that in at least various releases of JunOS circa 4.4, that
error message was appearing on Cisco's without causing any adverse
effects other than annoying log messages.  I had a case open with
juniper about this which was closed in late 2001.  Their statement at
the time was that JunOS4.4R3 should have eliminated the problem.

Then, last month while working on the iGrid network, I noticed that my
home site's MSDP peer (JunOS 5.5(something)) was causing these errors
on the iGrid MSDP peer, which was running IOS 12.1.13.  We've changed
JunOS versions since then, and I haven't had any reports of the logs
persisting.  As a result, I hadn't reported it to Juniper.

I thought that Tom Pusateri made some comments about the problem on
this list some time ago, but I can't find it in my archives.

It is, of course, possible that this is something new.
