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

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

This section provides an example for configuring IPv6 user-side multicast for PPPoE access users.

Networking Requirements

On the network shown in Figure 15-4, users (PC1) are PPPoE access users, and they want to join multicast programs. Configure IPv6 user-side multicast to implement user-based on-demand multicast data forwarding.

Figure 15-4 Configuring IPv6 user-side multicast for PPPoE 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 PPPoE access mode:

    1. Configure a virtual template (VT) interface.

    2. Bind a VT to an interface.

    3. Bind a sub-interface to a VLAN.

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

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

  7. Configure basic multicast functions:

    1. Enable IPv6 multicast routing.

    2. Enable IPv6 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
  • VT number
  • 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. Configure a VT interface.

    [~BRAS] interface virtual-template 100
    [*BRAS-Virtual-Template100] ppp authentication-mode chap
    [*BRAS-Virtual-Template100] quit
    [*BRAS] commit

  6. Bind a sub-interface to a VLAN and specify a VT interface for the sub-interface.

    [~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] pppoe-server bind virtual-template 100
    [*BRAS-GigabitEthernet1/0/1.1] commit

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

    [~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] quit
    [*BRAS-GigabitEthernet1/0/1.1] quit
    [*BRAS] commit
    # Run the display access-user domain wdomain command to check information about users that have gone online. The command output shows that the user with the user ID 65 has gone online in PPPoE mode.
    [~BRAS] display  access-user domain wdomain
      ------------------------------------------------------------------------------
      UserID  Username                Interface      IP address       MAC
              Vlan          IPv6 address             Access type
      ------------------------------------------------------------------------------
      65      spirent33@wdomain       GE1/0/1.1      -                0010-cc00-27e9
              133/-         2015::10:CC00:200:27E9   PPPoE
      ------------------------------------------------------------------------------
      Normal users                       : 1
      RUI Local users                    : 0
      RUI Remote users                   : 0
      Total users                        : 1

  8. Enable multicast replication by multicast VLAN on a BAS interface.

    [~BRAS] interface gigabitethernet 1/0/1.1
    [*BRAS-GigabitEthernet1/0/1.1] multicast user-aggregation vlan 81
    [*BRAS-GigabitEthernet1/0/1.1] commit
    [~BRAS-GigabitEthernet1/0/1.1] quit

  9. 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

  10. Verify the configuration.
