IPv6 PIM-SM Configuration Example
Network requirements
z
Receivers receive VOD information through multicast. The receiver groups of different
organizations form stub networks, and one or more receiver hosts exist in each stub network. The
entire PIM domain operates in the sparse mode.
z
Host A and Host C are IPv6 multicast receivers in two stub networks N1 and N2.
z
Switch D connects to the network that comprises the IPv6 multicast source (Source) through
VLAN-interface 300.
z
Switch A connects to N1 through VLAN-interface 100, and to Switch D and Switch E through
VLAN-interface 101 and VLAN-interface 102 respectively.
z
Switch B and Switch C connect to N2 through their respective VLAN-interface 200, and to Switch E
through VLAN-interface 103 and VLAN-interface 104 respectively.
z
Vlan-interface 105 on Switch D and Vlan-interface 102 on Switch E act as C-BSRs and C-RPs; the
C-BSR on Switch E has a higher priority; the IPv6 multicast group range served by the C-RP is
FF0E::101/64; modify the hash mask length to map a certain number of consecutive IPv6 group
addresses within the range to the two C-RPs.
z
MLDv1 is to run between Switch A and N1, and between Switch B/Switch C and N2.
