all: Removes all static IPv6 multicast groups that the current interface has joined.

ipv6-group-address: IPv6 multicast group address, in the range of FFxy::/16 
(excluding FFx0::/16, FFx1::/16, FFx2::/16, and FF0y), where x and y represent any 
hexadecimal number ranging from 0 to F.

ipv6-source-address: IPv6 address of the specified multicast source.

Use the mld static-group command to configure the current interface to be a 
statically-connected member of the specified IPv6 multicast group.
