Brocade(config)#router pim
Brocade(config-pim-router)#ssm-enable range 232.1.1.1/8
Syntax: [no] ssm-enable range group-address address-mask
The group-address parameter specifies the multicast address for the SSM address range.If this is
not configured, the range will default to 232/8 as assigned by the Internet Assigned Numbers
Authority (IANA) for use with SSM.
The address-mask parameter specifies the mask for the SSM address range.
To disable SSM, use the [no] form of this command.
Displaying source-specific multicast configuration information
To display PIM Sparse configuration information, use the show ip pim sparse command as
described in
“Displaying basic PIM Sparse configuration information” .
Configuring multiple SSM group ranges
The ssm-enable range acl-id/acl-name command allows you to configure multiple SSM group
ranges using an ACL.
Configuration Considerations
• The existing ssm-enable range group-address address-mask command will continue to exist.
• The ACL must be configured with the SSM group address in the permit clause of the
ssm-enable range acl-id or acl-name command. If the ssm-enable range group-address
address-mask command permits a clause, then that group will also operate in the PIM-SM
mode.
• If the ssm-enable range acl-id or acl-name command is configured with a non-existent or
empty ACL, then the SSM group will operate in PIM-SM mode (non PIM-SSM mode). However
when an ACL is added or updated, then the group will exist in a PIM-SSM mode. By default, an
empty ACL will deny all.
• By default, the group address mentioned in the IGMPv2 ssm-mapping ACL will decide if the
group address is a PIM-SSM group or non PIM-SSM group. Therefore, if a user wants to prevent
a group from operating in PIM-SSM mode, then the user’s configuration must consistently deny
the group in all configuration options for PIM-SSM range.
• ACL of any type (named or unnamed, standard or extended) can be used to specify the SSM
group range. If an extended ACL is used, then the destination ip address should be used to
specify the group address. Any configuration in the source address of an extended ACL is
ignored. Only permit statements are considered in the ACL configuration. Any deny statements
in the ACL clause are also ignored.
To configure multiple SSM group address using an ACL, enter the following command under the
router pim configuration:
Brocade(config)#router pim
Brocade(config-pim-router)#ssm-enable range xyz
The example displayed above configures PIM so that it uses the group addresses allowed by ACL,
xyz as its PIM SSM range.
