I'm trying to get the multicast stuff working in V2.0R and am having some 
problems.  I want to run mrouted on the same machine as I'm running the 
various tools (e.g. vat, nv, etc.) 

According to the FAQ to bring up multicast support you need to build a 
kernel with 

	options		MROUTING
	options		MULTICAST
	options		LKM

then load the file "ip_mroute_mod".  I built the kernel, and mrouted does 
indeed run.  When I try to load the "ip_mroute_mod.o" module using the 
command

	modload /lkm/ip_mroute_mod.o

I get billions of error messages, and modstat reports nothing loaded (I 
suspect I'm not doing this right, but there are no instructions for how 
to do it, so...)

No matter what I do I can't get anything to show up in sd, and vat does 
not function.  When I fire up mrouted I *DO* see traffic over the link, 
and "mrouted -d" yields:

  debug level 2
  mrouted version 3.3
  installing ed0 (198.116.75.11 on subnet 198.116.75) as vif #0 - rate=0
  installing tunnel from 198.116.75.11 to 198.116.2.105 as vif #1 - rate=2
  pruning on

  update 137 starting at 0 of 513

but I, as I said, sd/vat don't function.  The mrinfo utility shows:

   #mrinfo 198.116.75.11
   198.116.75.11 (mcn-test1.eco.nsi.nasa.gov) [version 3.3]:

     198.116.75.11 -> 198.116.2.105 (camelot.nsi.nasa.gov) [1/32/tunnel]

   #mrinfo 198.116.2.105
   198.116.2.105 (camelot.nsi.nasa.gov) [version 3.3]:
     198.116.2.105 -> 198.116.2.100 (lupine.nsi.nasa.gov) [1/1]
     198.116.2.105 -> 198.116.2.108 (jeeves.nsi.nasa.gov) [1/1]
     198.116.2.105 -> 198.116.75.11 (mcn-test1.eco.nsi.nasa.gov) [1/32/tunnel]


I've looked in the email archives but haven't found any answers;  does
anyone have an idea?

Thanks,

Mike
