◆ Group addresses within the entire multicast group address range can
be specified. However, if any address within the source-specific
multicast (SSM) address range (default 232/8) is specified, but no
source address is included, the request to join the multicast group will
fail unless the next node up the reverse path tree has statically mapped
this group to a specific source address. Also, if an address outside of
the SSM address range is specified, and a specific source address is
included in the command, the request to join the multicast group will
also fail if the next node up the reverse path tree has enabled the PIM-
SSM protocol.
◆ If a static group is configured for an any-source multicast (*,G), a
source address cannot subsequently be defined for this group without
first deleting the entry.
◆ If a static group is configured for one or more source-specific multicasts
(S,G), an any-source multicast (*,G) cannot subsequently be defined
for this group without first deleting all of the associated (S,G) entries.
