Example for Configuring Basic IPv6 PIM-DM Functions

Procedure

1. Configure IPv6 addresses for interfaces and configure a unicast routing protocol on the routers.

   # Configure IPv6 addresses and masks for router interfaces. Configure Open Shortest Path First version 3 (OSPFv3) on the routers to implement IPv6 interworking between the routers and enable the routers to dynamically update routes. (The configurations of the other routers are similar to the configuration of RouterA.)

   <Huawei> system-view
   [Huawei] sysname RouterA
   [RouterA] ipv6
   [RouterA] ospfv3 100
   [RouterA-ospfv3-100] router-id 1.1.1.1
   [RouterA-ospfv3-100] quit
   [RouterA] interface gigabitethernet 1/0/0
   [RouterA-GigabitEthernet1/0/0] ipv6 enable
   [RouterA-GigabitEthernet1/0/0] ipv6 address 2005::1 64
   [RouterA-GigabitEthernet1/0/0] ospfv3 100 area 0
   [RouterA-GigabitEthernet1/0/0] quit
   [RouterA] interface gigabitethernet 2/0/0
   [RouterA-GigabitEthernet2/0/0] ipv6 enable
   [RouterA-GigabitEthernet2/0/0] ipv6 address 3001::1 64
   [RouterA-GigabitEthernet2/0/0] ospfv3 100 area 0
   [RouterA-GigabitEthernet2/0/0] quit
   [RouterA] interface gigabitethernet 3/0/0
   [RouterA-GigabitEthernet3/0/0] ipv6 enable
   [RouterA-GigabitEthernet3/0/0] ipv6 address 2001::1 64
   [RouterA-GigabitEthernet3/0/0] ospfv3 100 area 0
   [RouterA-GigabitEthernet3/0/0] quit
   

2. Enable multicast routing on all the routers and enable IPv6 PIM-DM on all interfaces.

   # Enable multicast routing on all the routers and enable IPv6 PIM-DM on all interfaces. (The configurations of the other routers are similar to the configuration of RouterA.)

   [RouterA] multicast ipv6 routing-enable
   [RouterA] interface gigabitethernet 1/0/0
   [RouterA-GigabitEthernet1/0/0] pim ipv6 dm
   [RouterA-GigabitEthernet1/0/0] quit
   [RouterA] interface gigabitethernet 2/0/0
   [RouterA-GigabitEthernet2/0/0] pim ipv6 dm
   [RouterA-GigabitEthernet2/0/0] quit
   [RouterA] interface gigabitethernet 3/0/0
   [RouterA-GigabitEthernet3/0/0] pim ipv6 dm
   [RouterA-GigabitEthernet3/0/0] quit

3. Enable MLD on the interfaces connected to user hosts.

   # Enable MLD on the user-side interface of RouterA. (The configurations of RouterB and RouterC are similar to the configuration of RouterA.)

   [RouterA] interface gigabitethernet 2/0/0
   [RouterA-GigabitEthernet2/0/0] mld enable
   [RouterA-GigabitEthernet2/0/0] quit
   

4. Verify the configuration.

   # Run the display pim ipv6 interface command to check the IPv6 PIM configuration and running status on router interfaces. The following is the command output on RouterC, indicating that IPv6 PIM is running on the interfaces.

   <RouterC> display pim ipv6 interface
   VPN-Instance: public net
   Interface      State   NbrCnt   HelloInt   DR-Pri     DR-Address
   GE1/0/0        up      0         30         1         FE80::10B:FF:F301:22(local)
   GE2/0/0        up      1         30         1         FE80::10B:FF:F301:22(local)

   # Run the display pim ipv6 routing-table command to check the PIM routing tables on the routers. You can see from the PIM routing tables that multicast source (5001::100/64) to group (FF0E::1/64), and HostA and HostB have joined group (FF0E::1/64). The IPv6 PIM routing tables of the routers are as follows:

   [RouterA] display pim ipv6 routing-table
   VPN-Instance: public net
