Configuring a Service
Loop Group for IPv6
Multicast and IPv6
Unicast
Configure an IPv6 multicast and/or an IPv6 unicast service loop group to
implement Centralized Mode IPv6 multicast and/or IPv6 unicast. For details about
a loop group, refer to
“Configuring a Service Loop Group” on page 79.
Follow these steps to configure an IPv6 multicast service loop group:
c
CAUTION:
■ Before adding an Ethernet port into a service loop group for IPv6 multicast or
Iv6 unicast, be sure that this port is on an IPv6-capable module.
■ Before adding an Ethernet port into a service loop group for IPv6 multicast or
IPv6 unicast, make sure that STP is disabled on port.
n
■ Only one IPv6 multicast service loop group can be configured in the system.
■ No more than 8 ports can be added to the IPv6 multicast or Iv6 unicast service
service loop group.
Configuring IPv6
Multicast and IPv6
Unicast Centralized
Mode Example
Network requirements
■ Receivers receive VOD information through multicast. The receiver groups of
different organizations form two stub networks, and at least one receiver host
exists in each stub network. The entire IPv6 PIM domain operates in the dense
mode.
■ Due to some restrictions, Switch B and Switch C connect to Switch A through
ports on their respective IPv4 modules in slot 3. An IPv6 board is installed in slot
2 on Switch B and Switch C respectively.
■ Configure Centralized Mode for IPv6 multicast and IPv6 unicast so that Switch
B and Switch C can forward IPv6 multicast and IPv6 unicast data normally.
