Network requirements
Receivers receive VOD information through the multicast mode. Receivers of
■
different organizations form stub networks N1 and N2, and Host A and Host C
are receivers in N1 and N2 respectively.
Switch A in the PIM network connects to N1, and both Switch B and Switch C
■
connect to N2.
Switch A connects to N1 through VLAN-interface 100, and to other devices in
■
the PIM network through VLAN-interface 101.
Switch B and Switch C connect to N2 through their respective VLAN-interface
■
200, and to other devices in the PIM network through VLAN-interface 201 and
VLAN-interface 202 respectively.
IGMPv3 is required between Switch A and N1. IGMPv2 is required between the
■
other two switches and N2, with Switch B as the IGMP querier.
Use the command...

interface-number ] [ verbose ]
