Could not understand the relation between MVR and IGMP Snooping reading DOC CD.

======
quoted

However, if IGMP snooping and MVR are both enabled, MVR reacts only to join and leave messages from multicast groups configured under MVR. Join and leave messages from all
other multicast groups are managed by IGMP snooping.

=======

The only way router B (vlan 23) receives multicast from router A (vlan 12) is statically configuring
it (mvr vlan 12 group x.x.x.x)

Any comments appreciated.
