Associates a prefix list with a source address, known as Source Specific Multicast (SSM) mapping.
By default, SSM mapping is not enabled.
VLAN or bridge domain configuration mode
Use the no ipv6 mld ssm-map enable form of the command to disable SSM mapping on the indicated prefix and IPv6 address.
The following example maps IPv6 address 2::100 to a prefix list named prefix1.
device# configure terminal devicee(config)# vlan 10 device(config-vlan-10)# ipv6 mld ssm-map prefix1 2::100
