information from only Source 2. Source 3 sends multicast information to multicast group 224.1.1.1.
Host C is a multicast receiver for this multicast group.
z
VLAN-interface 101 of Switch B acts as a C-BSR and C-RP of admin-scope zone 1, which serve
the multicast group range 239.0.0.0/8. VLAN-interface 104 of Switch D acts as a C-BSR and C-RP
of admin-scope zone 2, which also serve the multicast group range 239.0.0.0/8. Both
VLAN-interface 109 of Switch F and VLAN-interface 110 of Switch H act as C-BSRs and C-RPs of
the global scope zone, which serve all the multicast groups other than those in the 239.0.0.0/8
range. Switch F has a higher priority.
z
IGMPv2 is required between Switch A, Switch E, Switch I and their respective receivers.
