Example for Configuring IPv6 User-Side Multicast for IPoE Access Users

Example for Configuring IPv6 User-Side Multicast for IPoE Access Users

This section provides an example for configuring IPv6 user-side multicast service for Internet Protocol over Ethernet (IPoE) access users.

Networking Requirements

On the network shown in Figure 15-5, users (PC) are IPoE access users, and they want to join multicast programs. Configure IPv6 user-side multicast to implement user-based on-demand multicast data forwarding.

Figure 15-5 Configuring IPv6 user-side multicast for IPoE access users
NOTE:

Interface 1 and interface 2 in this example stand for GE 1/0/0 and GE 1/0/1.1, respectively.



Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure Authentication, Authorization and Accounting (AAA) schemes.

  2. Configure a local IPv6 prefix pool.

  3. Configure a local IPv6 address pool and bind the local IPv6 prefix pool to the local address pool.

  4. Configure an AAA domain and bind it to the IPv6 address pool.

  5. Configure the IPoE access mode:

    1. Configure an authentication scheme.

    2. Bind a sub-interface to a VLAN.

    3. Configure a BAS interface and specify a user access type for the interface.

  6. Configure a multicast replication mode. Multicast replication by interface + VLAN is used as an example.

  7. Configure basic multicast functions:

    1. Enable IPv6 multicast routing.

    2. Enable IPv6 Protocol Independent Multicast-Sparse Mode (PIM-SM) on all BRAS interfaces.

    3. Enable MLD on the BRAS interface connected to users.

Data Preparation

  • Local prefix pool, address prefix, and prefix length parameters

  • Local address pool parameters

  • Authentication and accounting schemes

  • User domain
  • BAS interface parameters

Procedure

  1. Configure AAA schemes.

    # Configure an authentication scheme.

    <HUAWEI> system-view
    [HUAWEI] sysname BRAS
    [*HUAWEI] commit
    [~BRAS] aaa
    [*BRAS-aaa] authentication-scheme none
    [*BRAS-aaa-authen-none] authentication-mode none
    [*BRAS-aaa-authen-none] quit
    [*BRAS-aaa] commit

    # Configure an accounting scheme.

    [~BRAS-aaa] accounting-scheme none
    [*BRAS-aaa-accounting-none] accounting-mode none
    [*BRAS-aaa-accounting-none] quit
    [*BRAS-aaa] quit
    [*BRAS] commit

  2. Configure a local IPv6 prefix pool.

    [~BRAS] ipv6 prefix ipv6 local
    [*BRAS-ipv6-prefix-ipv6] prefix 2015::/64
    [*BRAS-ipv6-prefix-ipv6] quit
    [*BRAS] commit

  3. Configure a local IPv6 address pool and bind the local IPv6 prefix pool to the local address pool.

    [~BRAS] ipv6 pool ipv6 bas local
    [*BRAS-ipv6-pool-ipv6] prefix ipv6
    [*BRAS-ipv6-pool-ipv6] quit
    [*BRAS] commit

  4. Configure a domain and bind the local address pool to the domain.

    [~BRAS] aaa
    [*BRAS-aaa] domain wdomain
    [*BRAS-aaa-domain-wdomain] authentication-scheme none
    [*BRAS-aaa-domain-wdomain] accounting-scheme none
    [*BRAS-aaa-domain-wdomain] ipv6-pool ipv6
    [*BRAS-aaa-domain-wdomain] quit
    [*BRAS-aaa] quit
    [*BRAS] commit

  5. Bind a sub-interface to a VLAN.

    [~BRAS] interface gigabitethernet 1/0/1.1
    [*BRAS-GigabitEthernet1/0/1.1] user-vlan 133
    [*BRAS-GigabitEthernet1/0/1.1-vlan-133-133] quit
    [*BRAS-GigabitEthernet1/0/1.1] commit

  6. Configure a BAS interface and specify a user access type for the interface, and configure an authentication scheme.

    [~BRAS-GigabitEthernet1/0/1.1] bas
    [*BRAS-GigabitEthernet1/0/1.1-bas] access-type layer2-subscriber default-domain authentication wdomain
    [*BRAS-GigabitEthernet1/0/1.1-bas] authentication-method bind
    [*BRAS-GigabitEthernet1/0/1.1-bas] quit
    [*BRAS-GigabitEthernet1/0/1.1] quit
    [*BRAS] commit

  7. Enable multicast replication by interface + VLAN on a BAS interface.

    [~BRAS] interface gigabitethernet 1/0/1.1
    [~BRAS-GigabitEthernet1/0/1.1] bas
    [*BRAS-GigabitEthernet1/0/1.1-bas] multicast copy by-vlan
    [*BRAS-GigabitEthernet1/0/1.1-bas] commit
    [~BRAS-GigabitEthernet1/0/1.1-bas] quit

  8. Configure basic multicast functions.

    [~BRAS] multicast ipv6 routing-enable
    [*BRAS] interface gigabitethernet 1/0/0
    [*BRAS-GigabitEthernet1/0/0] undo shutdown
    [*BRAS-GigabitEthernet1/0/0] ipv6 enable
    [*BRAS-GigabitEthernet1/0/0] ipv6 address 2001:db8:1::1/64
    [*BRAS-GigabitEthernet1/0/0] pim ipv6 sm
    [*BRAS-GigabitEthernet1/0/0] quit
    [*BRAS] commit
    [~BRAS] interface gigabitethernet 1/0/1.1
    [~BRAS-GigabitEthernet1/0/1.1] ipv6 enable
    [*BRAS-GigabitEthernet1/0/1.1] ipv6 address auto link-local
    [*BRAS-GigabitEthernet1/0/1.1] pim ipv6 sm
    [*BRAS-GigabitEthernet1/0/1.1] mld enable
    [*BRAS-GigabitEthernet1/0/1.1] quit
    [*BRAS] commit

  9. Verify the configuration.

    # Run the display multicast group-ip command to display information about users of a specified multicast group. The command output shows that the user with ID 65 joins multicast programs whose group address is FF18::1.
