32.1.8 IPv6 PIM-SSM Setting

<Structure of this section>

(1) IPv6 PIM-SSM Address Setting

Points to note: The following configuration is performed in global configuration mode to enable use of IPv6 PIM-SSM for the Switches. The configuration causes IPv6 PIM-SSM to run within the specified SSM address range on interfaces for which IPv6 PIM-SM is set. Only one SSM address setting can be used on the Switch. In this example, ff35::/16 is specified as the SSM address range for which PIM-SSM runs.

Command examples

(config)# ipv6 access-list GROUP2

(config-ipv6-acl)# permit ipv6 any ff35::/16

(config-ipv6-acl)# exit

Creates an access list for an SSM address range.
(config)# ipv6 pim ssm range GROUP2

Enables the use of IPv6 PIM-SSM. (The access list created in step 1 is used to specify the SSM address range.)

(2) Set IPv6 PIM-SSM to work together in MLDv1/MLDv2(EXCLUDE mode.)

Points to note

Because source addresses cannot be differentiated with MLDv1 or MLDv2 (EXCLUDE mode), linkage to the PIM-SSM cannot be performed. With the Switch, the group address and source address for which PIM-SSM is run can be set to link with PIM-SSM. In the following PIM-SSM configuration example, ff35::1 is used as the group address when two servers are used with 2001:db8::aa:1 as the source address of server 1, and 2001:db8::bb:1 as the source address of server 2.

Command examples

(config)# ipv6 access-list GROUP3

(config-ipv6-acl)# permit ipv6 any host ff35::1

(config-ipv6-acl)# exit

Creates an access list for which the group address is specified.
(config)# ipv6 mld ssm-map static GROUP3 2001:db8::aa:1

(config)# ipv6 mld ssm-map static GROUP3 2001:db8::bb:1

Sets the group address for which PIM-SSM is run, and the source addresses for server 1 and server 2. (The access list created in step 1 is used to specify the group address.)
(config)# ipv6 mld ssm-map enable

Enables the use of IPv6 PIM-SSM.
