Source 1 and Source 2 send different multicast information to FF14::101. Host A receives the multicast
information from Source 1 only, and Host B receives the multicast information from Source 2 only. Source
3 sends multicast information to FF1E::202. Host C is a multicast receiver for this multicast group.
Serial 2/1 of Router B acts as a C-BSR and C-RP of IPv6 admin-scoped zone 1, which serve the IPv6
multicast groups with the Scope field value in their group addresses being 4. Serial 2/1 of Router D acts
as a C-BSR and C-RP of admin-scoped zone 2, which also serve the IPv6 multicast groups with the Scope
field value in their group addresses being 4. Serial 2/1 of Router F acts as a C-BSR and a C-RP of the
global-scoped zone, which serve IPv6 multicast groups with the Scope field value in their group
addresses being 14.
MLDv1 runs between Router A, Router E, Router I ,and their respective receivers.
