Checking the Current Global PIM Status
To view current global PIM enable/disable status, as well as additional global PIM settings, use the
show
ip pim sparse
or
show ip pim dense
command. For example:
-> show ip pim sparse
Status = enabled,
Keepalive Period = 210,
Max RPs = 32,
Probe Time = 5,
Register Checksum = header,
Register Suppress Timeout = 60,
RP Threshold = 1,
SPT Status = enabled,
-> show ip pim dense
Status = enabled,
Source Lifetime = 210,
State Refresh Interval = 60,
State Refresh Limit Interval = 0,
State Refresh TTL = 16
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), use the
ip pim dense group
command. For example:
-> ip pim dense group 224.0.0.0/4 priority 50
This command entry maps the multicast group 224.0.0.0/4 to PIM-DM 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 configura-
tion 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 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
