Configuring IPv6 Multicast

2.configure terminal

3.ipv6 mld [vrf vrf-name]ssm-map enable

4.ipv6 mld [vrf vrf-name]ssm-map static access-list source-address

5.no ipv6 mld [vrf vrf-name]ssm-map query dns

DETAILED STEPS

	Command	Purpose
Step 1	enable	Enables privileged EXEC mode.
		• Enter your password if prompted.
	Example:
	Router> enable
Step 2	configure terminal	Enters global configuration mode.

Step 3	ipv6 mld [vrf vrf-name]ssm-map enable	Enables the SSM mapping feature for groups in the configured SSM
		range.
	Example:	Note You should first create ACL to define the group that needs
	Router(config-if)# ipv6 mld ssm-map	to be mapped.
	enable
Step 4	ipv6 mld [vrf vrf-name]ssm-map static	Configures static SSM mappings.
	access-list source-address
	Example:
	Router(config-if)# ipv6 mld ssm-map
	static SSM_MAP_ACL_2 2001:DB8:1::1
Step 5	no ipv6 mld [vrf vrf-name]ssm-map	Disables DNS-based SSM mapping.
	query dns	Note You must disable SSM-map query dns when static mapping
	Example:	is configured.
	Router(config-if)# ipv6 mld ssm-map
	query dns
