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

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]:

198.116.2.105 -> 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
