Mapping an IP Multicast Group to a PIM Mode
PIM mode is an attribute of the IP multicast group mapping and cannnot be configured on an interface
basis. The Dense mode or Source-Specific Multicast mode can be configured only on a multicast group
basis.
Mapping an IP Multicast Group to PIM-DM
To statically map an IP multicast group(s) to PIM-Dense mode (DM), you can use the ip pim dense group
command. For example:
-> ip pim dense group 224.0.0.0/4 priority 50
This command entry maps all multicast groups 224.0.0.0/4 to PIM-Dense mode and specifies the priority
value to be used for the entry as 50. This priority specifies the preference value to be used for this static
configuration and provides fine control over which configuration is overridden by this static configura-
tion. Values may range from 0 to 128. If the priority option has been defined, a value of 65535 can be used
to unset the priority.
You can also specify whether or not this static configuration overrides the dynamically learned group
mapping information for the specified group using the override parameter. As specifying the priority
value obsoletes the override option, you can use either the priority or override parameter only. By
default, the priority option is not set, and the override option is set to false.
Use the no form of this command to remove a static configuration of a dense mode group mapping.
-> no ip pim dense group 224.0.0.0/4
Mapping an IP Multicast Group to PIM-SSM
To statically map an IP multicast group(s) to PIM-Source-Specific Multicast mode (SSM), you can use the
ip pim ssm group command. For example:
-> ip pim ssm group 224.0.0.0/4 priority 50
This command entry maps all multicast groups 224.0.0.0/4 to PIM-SSM mode and specifies the priority
value to be used for the entry as 50. This priority specifies the preference value to be used for this static
configuration and provides fine control over which configuration is overridden by this static configura-
tion. Values may range from 0 to 128. If the priority option has been defined, a value of 65535 can be used
to unset the priority.
