Solaris multicast config

2007-12-24 20:03:00

OK, what am I missing here? I'm trying to configure multicast interfaces on a
couple of Solaris 2.7 machines.

Things "look" OK--'netstat -r' shows a reasonable looking route, ifconfig shows
reasonable interfaces...however. I cannot:
ping 224.0.0.1
ping 237.0.0.32

Using the Weblogic java test app utils.MulticastTest implies that the localhost
is seeing multicast traffic, but doesn't show any other group members (there
should be 2 machines).

Any suggestions?
