Network requirements

l          Receivers receive VOD information in the multicast mode. Receivers of different organizations form stub networks N1 and N2, and Host A and Host C are multicast receivers in N1 and N2 respectively.

l          Switch A in the IPv6 PIM network connects to N1, and Switch B and Switch C connect to N2.

l          Switch A connects to N1 through VLAN-interface 100, and to other devices in the IPv6 PIM network through VLAN-interface 101.

l          Switch B and Switch C connects to N2 through their own VLAN-interface 200, and to other devices in the IPv6 PIM network through VLAN-interface 201 and VLAN-interface 202 respectively.

l          MLDv1 is required between Switch A and N1. MLDv1 is also required between the other two switches (Switch B and Switch C) and N2, Switch B serves as the MLD querier in N2 because its IP address is lowe.

l          On Switch A, specify the IGMP query interval to 30 seconds, the maximum response time to 5 seconds, and the IGMP last member query interval to 2 seconds.

Configuration procedure

1)        Enable IPv6 forwarding and configure IPv6 addresses and IPv6 unicast routing

Enable IPv6 forwarding on each switch and configure an IP address and prefix length for each interface as shown in Figure 1-1 The detailed configuration steps are not discussed in this document.

Configure OSPFv3 for interoperation between the switches. Ensure the network-layer interoperation among the switches on the IPv6 PIM network and dynamic update of routing information between the switches through a unicast routing protocol. The detailed configuration steps are omitted here.

2)        Enable the IPv6 multicast routing, and enable IPv6 PIM-DM and MLD.

[SwitchC] interface vlan-interface 202

[SwitchC-Vlan-interface202] pim ipv6 dm

[SwitchC-Vlan-interface202] quit

3)        Verify the configuration

Carry out the display mld interface command to display the MLD configuration and running information on each switch interface. Example:

# Display MLD information on VLAN-interface 200 of Switch B.

[SwitchB] display mld interface vlan-interface 200

 Vlan-interface200(FE80::200:5EFF:FE66:5100):

   MLD is enabled

   Current MLD version is 1

   Value of query interval for MLD(in seconds): 125

   Value of other querier present interval for MLD(in seconds): 255

   Value of maximum query response time for MLD(in seconds): 10

   Querier for MLD: FE80::200:5EFF:FE66:5100 (this router)

Network requirements

l          On the IPv6 PIM-SSM network shown in Figure 1-2, the receiver host receives VOD information through multicast. The receiver runs MLDv1, so it cannot specify the expected IPv6 multicast sources in its reports.

l          The receiver host joins a multicast group in the range of FF3E::/64.

l          It is required that MLD SSM mapping be configured on Switch D so that the receiver host will receive IPv6 multicast data from Source 1 and Source 3 only.

Configuration guidelines

l          To ensure SSM service for all hosts on a subnet, regardless of the MLD version running on the hosts, enable MLDv2 on the interface that forwards IPv6 multicast traffic onto the subnet.

l          If MLDv2 is enabled on a VLAN interface of an switch, and if a port in that VLAN is configured as a simulated host, the simulated host will send MLDv2 reports even if you did not specify an IPv6 multicast source when configuring simulated joining with the mld-snooping host-join command. In this case, the corresponding IPv6 multicast group will not be created based on the configured MLD SSM mappings.

Network diagram

Networking and configuration requirements

l          As shown in Figure 1-3, Router A connects to the IPv6 multicast source through GigabitEthernet 1/0/2 and to Switch A through GigabitEthernet 1/0/1.

l          MLDv1 is required on Router A, MLD Snooping version 1 is required on Switch A, and Router A will act as the MLD querier on the subnet.

l          It is required that the receivers, Host A and Host B, attached to Switch A can receive IPv6 multicast traffic addressed to IPv6 multicast group FF1E::101 only.

l          It is required that the receivers, Host A and Host B, attached to Switch A can receive IPv6 multicast traffic; multicast traffic can be forwarded through GigabitEthernet 1/0/3 and GigabitEthernet 1/0/4 of Switch A even if Host A and Host B accidentally, temporarily stop receiving IPv6 multicast data.

Configuration guildlines

l          Layer 2 and Layer 3 multicast protocols can run simultaneously on a switch, but a Layer 2 multicast protocol cannot run on a switch while a Layer 3 multicast protocol is running on the virtual interface of that VLAN, and vice versa.

l          MLD Snooping must be enabled globally in system view before it can be enabled in a VLAN.

l          Unlike a static member port, a port configured as a simulated member host will age out like a dynamic member port.

Configuring Static Ports

Network diagram

Figure 1-4 Network diagram for static router port configuration

 

Networking and configuration requirements

l          When receivers are interested in multicast data addressed to a particular group, you can configure a static port to enhance the reliability of multicast data transmission.

l          As shown in Figure 1-4, Router A connects to an IPv6 multicast source (Source) through GigabitEthernet 1/0/2, and to Switch A through GigabitEthernet 1/0/1.

l          MLD is to run on Router A, and MLD Snooping is to run on Switch A, Switch B and Switch C, with Router A acting as the MLD querier.

l          Suppose STP runs on the network. To avoid data loops, the forwarding path from Switch A to Switch C is blocked under normal conditions, and IPv6 multicast traffic flows to the receivers, Host A and Host C, attached to Switch C only along the path of Switch A—Switch B—Switch C.

l          Now it is required to configure GigabitEthernet 1/0/3 that connects Switch A to Switch C as a static router port, so that IPv6 multicast traffic can flow to the receivers nearly uninterruptedly along the path of Switch A—Switch C in the case that the path of Switch A—Switch B—Switch C gets blocked.

l          It is required to configure GigabitEthernet 1/0/3 and GigabitEthernet 1/0/5 on Switch C as static member ports for IPv6 multicast group FF1E::101, so that the attached two receivers can steadily receive IPv6 multicast data destined for that IPv6 multicast group.

Configuring MLD Snooping Querier

Network diagram

Figure 1-5 Network diagram for MLD Snooping querier configuration

 

Networking and configuration requirements

l          As shown in Figure 1-5, in a Layer-2-only network environment, two IPv6 multicast sources Source 1 and Source 2 send IPv6 multicast data to IPv6 multicast groups FF1E::101 and FF1E::102 respectively, Host A and Host C are receivers of IPv6 multicast group FF1E::101, while Host B and Host D are receivers of IPv6 multicast group FF1E::102.

l          MLDv1 is to run on all the receivers and MLD Snooping version 1 is to run on all the switches. Switch A, which is close to the IPv6 multicast sources, is chosen as the MLD Snooping querier.

l          To prevent flooding of unknown IPv6 multicast traffic within the VLAN, it is required to configure all the switches to drop unknown IPv6 multicast data packets.

Figure 1-6 Network diagram for Sub-VLAN-Based IPv6 multicast VLAN configuration

 

Networking and configuration requirements

l          As shown in Figure 1-6, Router A connects to an IPv6 multicast source (Source) through GigabitEthernet 1/0/2 and to Switch A through GigabitEthernet 1/0/1.

l          MLD is required on Router A, and MLD Snooping is required on Switch A. Router A acts as the MLD querier on the subnet.

l          On Switch A, GigabitEthernet 1/0/1 belongs to VLAN 1024, GigabitEthernet 1/0/2 through GigabitEthernet 1/0/4 belong to VLAN 11 through VLAN 13 respectively, and Host A through Host C are attached to GigabitEthernet 1/0/2 through GigabitEthernet 1/0/4.

l          Configure the IPv6 multicast VLAN feature so that Router A just sends IPv6 multicast data to VLAN 1024 rather than to each VLAN when the three hosts attached to Switch A need the IPv6 multicast data.

l          Host A and Host C are multicast receivers in two stub networks N1 and N2.

l          Switch D connects to the network that comprises the multicast source (Source) through VLAN-interface 300.

l          Switch A connects to N1 through VLAN-interface 100, and to Switch D through VLAN-interface 103.

l          Switch B and Switch C connect to N2 through their respective VLAN-interface 200, and to Switch D through VLAN-interface 101 and VLAN-interface 102 respectively.

l          MLDv1 is to run between Switch A and N1, and between Switch B/Switch C and N2.

Configuration procedure

1)        Enable IPv6 forwarding and configure IPv6 addresses and IPv6 unicast routing

Enable IPv6 forwarding on each switch and configure the IPv6 address and prefix length for each interface as perFigure 1-8. Detailed configuration steps are omitted here.

Configure OSPFv3 for interoperation among the switches in the PIM-DM domain. Ensure the network-layer interoperation in the PIM-DM domain and enable dynamic update of routing information among the switches through an IPv6 unicast routing protocol. Detailed configuration steps are omitted here.

2)        Enable IPv6 multicast routing, and enable IPv6 PIM-DM and MLD

# Enable IPv6 multicast routing on Switch A, enable IPv6 PIM-DM on each interface, and enable MLD on VLAN-interface 100, which connects Switch A to N1.

Assume that Host A needs to receive the information addressed to IPv6 multicast group G (FF0E::101). After IPv6 multicast source S (4001::100/64) sends IPv6 multicast packets to the IPv6 multicast group G, an SPT is established through traffic flooding. Switches on the SPT path (Switch A and Switch D) have their (S, G) entries. Host A sends an MLD report to Switch A to join IPv6 multicast group G, and a (*, G) entry is generated on Switch A. You can use the display pim IPv6 routing-table command to view the IPv6 PIM routing table information on each switch. For example:

# View the IPv6 PIM multicast routing table information on Switch A.

[SwitchA] display pim ipv6 routing-table

Network requirements

l          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.

l          Host A and Host C are IPv6 multicast receivers in two stub networks N1 and N2.

l          Switch D connects to the network that comprises the IPv6 multicast source (Source) through VLAN-interface 300.

l          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.

l          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.

l          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.

l          MLDv1 is to run between Switch A and N1, and between Switch B/Switch C and N2.

Configuration procedure

1)        Enable IPv6 forwarding and configure IPv6 addresses and IPv6 unicast routing

Enable IPv6 forwarding on each switch and configure the IPv6 address and prefix length for each interface as perFigure 1-9. Detailed configuration steps are omitted here.

Configure OSPFv3 for interoperation among the switches in the IPv6 PIM-SM domain. Ensure the network-layer interoperation in the IPv6 PIM-DM domain and enable dynamic update of routing information among the switches through an IPv6 unicast routing protocol. Detailed configuration steps are omitted here.

2)        Enable IPv6 multicast routing, and enable IPv6 PIM-SM and MLD

# Enable IPv6 multicast routing on Switch A, enable IPv6 PIM-SM on each interface, and enable MLD on VLAN-interface 300, which connects Switch A to N1.

Assume that Host A needs to receive information addressed to the IPv6 multicast group G (FF0E::100). The RP corresponding to the multicast group G is Switch E as a result of hash calculation, so an RPT will be built between Switch A and Switch E. When the IPv6 multicast source S (4001::100/64) registers with the RP, an SPT will be built between Switch D and Switch E. Upon receiving IPv6 multicast data, Switch A immediately switches from the RPT to the SPT. Switches on the RPT path (Switch A and Switch E) have a (*, G) entry, while switches on the SPT path (Switch A and Switch D) have an (S, G) entry. You can use the display pim ipv6 routing-table command to view the PIM routing table information on the switches. For example:

# View the IPv6 PIM multicast routing table information on Switch A.

[SwitchA] display pim ipv6 routing-table

Configuraion guidelines

l          All the interfaces of the same device must work in the same IPv6 PIM mode.

l          When configuring a C-RP, ensure a relatively large bandwidth between this C-RP and the other devices in the IPv6 PIM-SM domain.

l          An RP can serve multiple IPv6 multicast groups or all IPv6 multicast groups. Only one RP can forward IPv6 multicast traffic for an IPv6 multicast group at a moment.

l          Since a large amount of information needs to be exchanged between a BSR and the other devices in the IPv6 PIM-SM domain, a relatively large bandwidth should be provided between the C-BSR and the other devices in the IPv6 PIM-SM domain.

Configuration guidelines

l          To create an IPv6 MBGP peer group, you need to enable an existing IPv6 unicast peer group in IPv6 MBGP address family view.

l          Before adding an IPv6 MBGP peer to the IPv6 MBGP peer group, you need to add the corresponding IPv6 BGP unicast peer to the corresponding IPv6 BGP unicast peer group.
