21.3.4 MLD Typical Application
As shown in the following figure, add the Ethernet interfaces of Switch A and Switch
B to corresponding vlan, and start PIM6 on each vlan interface.
SwitchA
SwitchB
Vlan 2
Vlan 1
Vlan 1
Fig 21-3 Network Topology Diagram
The configuration procedure for SwitchA and SwitchB is as below:
(1) Configure SwitchA:
Switch (Config) #ipv6 pim multicast-routing
Switch (Config) #ipv6 pim rp-address 3FFE::1
Switch (Config) #interface vlan 1
Switch (Config-If-Vlan1) #ipv6 address 3FFE::1/64
Switch (Config-If-Vlan1) #ipv6 pim sparse-mode
(2) Configure SwitchB:
Switch (Config) #ipv6 pim multicast-routing
Switch (Config) #ipv6 pim rp-address 3FFE::1
Switch (Config) #interface vlan1
Switch (Config-If-Vlan1) #ipv6 address 3FFE::2/64
Switch (Config-If-Vlan1) #ipv6 pim sparse-mode
Switch (Config-If-Vlan1) #exit
Switch (Config) #interface vlan2
Switch (Config-If-Vlan2) #ipv6 address 3FFA::1/64
Switch (Config-If-Vlan2) #ipv6 pim sparse-mode
Switch (Config-If-Vlan2) #ipv6 mld query-timeout 150
21.3.5 MLD Troubleshooting
When configuring and using MLD protocol, MLD protocol may fail to work normally
due to physical connections, incorrect configuration and so on. So, users shall note the
following points:
