Multicasting-Router under Solaris 2.3
Ralph Schindler
We need help on installing a multicast router.

We can extent the SunOS4.1.x workstations with multi-casting,
but we don't know how to configure the server correct.
The documentation for solaris 2.2 was not helpful.
Thank you.

You need separate mrouted program on Solaris, there
is none delivered in stock Solaris 2.3, but there are
all the necessary things in the kernel to use multicast
traffic from the network when such is present.
Your option may as well be to have your ELC as tunnel
end-point, which just multicasts the traffic to the
local ethernet. If you have multiple TUNNELS, then
you would need more power at running it (SS-10).
Recently I needed such an end-point, and only practical option
was to port the mrouted-2.2 (for SunOS 4.1.x) to Solaris.
Now you don't need to rework the non-obvious compiler problem..
Go and pick:
ftp.funet.fi:/pub/unix/networking/multicast/SOLARIS/
mrouted2.2.sparc.5.3.tar.Z
The file has the source, and ready-to-use binaries.
I would much rather be able to use mrouted 3.x, which
quenches incoming datastream when nobody local is listening
on it -- get only what people actively receive, however
Solaris 2.3's /kernel/drv/ip suits only mrouted 2.x..
Will Solaris 2.4 have it ? I don't know.
A word of warning: Currently full feed of multicast traffics
is 400-600 kbits/s when some events (like InterOp) are going
on, and if your connection can't handle that, you are in for
trouble... (mrouted 3.x would help, though.)
With mrouted 2.x the option is to turn the router off completely.
not just turn off some single channel(s) :-(
