source address? Source is a regular unicast address, and whether the
class-d destination address is treated as SSM or ASM depends on the
local configuration ("ip pim ssm default" to only use 232/8 for SSM, or
configure an ACL matching your SSM group address and reference this via
"ip pim ssm range <acl>"). So if you want 224.1.x.x. treated as SSM,
just configure an appropriate acl..
