Mapping an IPv6 Multicast Group to a PIM Mode
PIM mode is an attribute of the IPv6 multicast group mapping and cannnot be configured on an interface
basis. The Dense mode or Source-Specific Multicast mode can be configured only on an IPv6 multicast
group basis.
Mapping an IPv6 Multicast Group to PIM-DM
To statically map an IPv6 multicast group(s) to PIM-Dense Mode (DM), you can use the ipv6 pim dense
group command. For example:
-> ipv6 pim dense group ff0e::1234/128 priority 50
This command maps the multicast group ff0e::1234/128 to PIM-DM and assigns a priority value of 50
to the entry. 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 configuration. 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 use the override parameter to specify whether or not this static configuration overrides the
dynamically learned group mapping information for the specified group. As specifying the priority value
obsoletes the override option, you can use only the priority parameter or the override parameter. 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 ipv6 pim dense group ff0e::1234/128
Mapping an IPv6 Multicast Group to PIM-SSM
To statically map an IPv6 multicast group(s) to PIM-Source-Specific Multicast mode (SSM), you can use
the ipv6 pim ssm group command. For example:
-> ipv6 pim ssm group ff30::1234:abcd/128 priority 50
This command entry maps the multicast group ff30::1234:abcd/128 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
configuration. Values may range from 0 to 128. If the priority option has been defined, a value of 65535
can be used to un-set the priority.
You can also use the override parameter to specify whether or not this static configuration overrides the
dynamically learned group mapping information for the specified group. As specifying the priority value
obsoletes the override option, you can use only the priority parameter or the override parameter. 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 SSM mode group mapping.
-> no ipv6 pim ssm group ff30::1234:abcd/128
The default SSM address range (FF3x::/32) reserved by the Internet Assigned Numbers Authority is not
enabled automatically for PIM-SSM and must be configured manually to support SSM. You can also map
additional IPv6 multicast address ranges for the SSM group using this command. However, the IPv6
multicast groups in the reserved address range can be mapped only to the SSM mode.
