Procedure
Step 1 Assign IP addresses to interfaces on all the switches according to Figure 14-1. The configuration
details are not provided here.
Step 2 Configure IS-IS IPv6 to implement interworking among switches and ensure that route costs are
the same. The configuration details are not provided here.
Step 3 Enable IPv6 multicast on all switches and enable IPv6 PIM-SM on each interface.
# Configure SwitchA. The configurations on SwitchB, SwitchC, SwitchD, and SwitchE are
similar to those on SwitchA, and are not provided here.
[SwitchA] multicast ipv6 routing-enable
[SwitchA] interface Vlanif10
[SwitchA-Vlanif10] pim ipv6 sm
[SwitchA-Vlanif10] quit
[SwitchA] interface Vlanif20
[SwitchA-Vlanif20] pim ipv6 sm
[SwitchA-Vlanif20] quit
[SwitchA] interface Vlanif30
[SwitchA-Vlanif30] pim ipv6 sm
[SwitchA-Vlanif30] quit
[SwitchA] interface Vlanif40
[SwitchA-Vlanif40] pim ipv6 sm
[SwitchA-Vlanif40] quit
[SwitchA] interface loopback 0
[SwitchA-LoopBack0] pim ipv6 sm
[SwitchA-LoopBack0] quit
Step 4 Configure an RP on SwitchA.
# Configure Loopback0 on SwitchA as an RP.
[SwitchA] pim-ipv6
[SwitchA-pim6] c-bsr 2000::1
[SwitchA-pim6] c-rp 2000::1
[SwitchA-pim6] quit
Step 5 Configure stable-preferred IPv6 multicast load splitting on SwitchE.
[SwitchE] multicast ipv6 load-splitting stable-preferred
Step 6 Configure interfaces on the host side of SwitchE to statically join the multicast groups in batches.
# Configure VLANIF140 to statically join multicast groups from FF13::1 to FF13::3.
[SwitchE] interface Vlanif140
[SwitchE-Vlanif140] mld static-group ff13::1 inc-step-mask 128 number 3
[SwitchE-Vlanif140] quit
Step 7 Verify the configuration about stable-preferred IPv6 multicast load splitting.
# The multicast source (2001::1/64) sends multicast data to multicast groups (FF13::1 to
FF13::3). Host A can receive the multicast data from the multicast source. On SwitchE, check
brief information about the IPv6 PIM routing table.
