configure pim ssm range
configure pim ssm range [default | policy <policy-name>]
Description
Configures the range of multicast addresses for PIM SSM.
Syntax Description
Default
By default, no SSM range is configured. Using this command with the
default
keyword sets the range
to 232.0.0.0/8. To reset the switch to the initial state, use the
unconfigure pim ssm range
command.
Usage Guidelines
You must disable PIM before configuring or unconfiguring a PIM-SSM range. Use the
disable pim
command.
Initially, no range is configured for SSM. After a range is configured, you can remove the range with the
unconfigure pim ssm range
command. If you wish to change the PIM SSM range, you must first
unconfigure the existing range, and then configure the new range.
SSM requires that hosts use IGMPv3 messages to register to receive multicast group packets. When a
range is configured for SSM, any IGMPv2 messages for an address in the range will be ignored. Also,
any IGMPv3 Exclude messages will be ignored.
NOTE
If a PIM-SSM range is configured, IGMPv2 messages and IGMPv3 exclude messages within the PIM-SSM range are
ignored on all IP interfaces, whether or not PIM-SSM is configured on the interfaces.
To specify a range different from the default PIM SSM range, you will need to create a policy file. The
match statement of the policy file contains the group addresses to be treated as PIM SSM addresses. For
example, to specify the PIM SSM address range as 232.0.0.0/8 and 233.0.0.0/8, you will use the
following policy file:
Entry extreme1 {
if match any {
nlri 232.0.0.0/8 ;
nlri 233.0.0.0/8 ;
}
then {
permit ;
}
}
default
Specifies the default address range, 232.0.0.0/8.
policy-name
Specifies a policy that defines the SSM address range.
