67-8 ipv6 mld ssm-map static
This command is used to configure static Source Specific Multicast (SSM) mappings. To disable this
feature, use the no command.
ipv6 mld ssm-map static ACCESS-LIST SOURCE-ADDRESS
no ipv6 mld ssm-map static ACCESS-LIST SOURCE-ADDRESS
Parameters
ACCESS-LIST
SOURCE-ADDRESS
Default
By default, no static entry is configured.
Command Mode
Global Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
The deployment of source specific multicast (SSM) allows the network service provider to manage the IP
multicast address easily.
When SSM is enabled, the last hop router will initiate to establish a source-based tree for the channel (S,
G) on receiving a (S, G) INCLUDE mode request falls in the SSM range from the attached MLDv2 hosts.
There are cases that the attached host is an MLDv1 host which only issue (*, G) requests. With the SSM
mapping, if the multicast group request falls in the SSM range, the router is able to map the (*, G) to a (S,
G) request based on the group address to source address mapping defined by the ipv6 mld ssm-map
static command. The router will then issue to establish the source-based tree for the mapped (S, G).
The command can be issued multiple times. A group address can be associated with multiple source
addresses if it is defined in multiple access lists. If multiple associations exist, the router will issue to
establish a (S, G) source-based tree for each S.
Example
This example shows how to enable the SSM mapping feature.
Switch# configure terminal
Switch(config)# ipv6 mld ssm-map static SSM_MAP_ACL_2 2001:0DB8:1::1
Switch(config)#
67-9 ipv6 mld version
Specifies a standard IPv6 access list that contains the multicast groups
to be mapped. To permit a group, specify "any" in source address field
and specify the group address in destination address field of the
access list entry.
Specifies the source address associated with an MLD membership for
a group identified by the access list.
