Configuring IGMP Dual-Device Hot Backup in a VRRP Master/Backup Scenario (Binding a Multicast Service Interface to a Common VRRP Backup Group)

Configuring IGMP Dual-Device Hot Backup in a VRRP Master/Backup Scenario (Binding a Multicast Service Interface to a Common VRRP Backup Group)

IGMP dual-device hot backup implements non-stop multicast service forwarding during a master/backup device switchover. This section describes how to configure IGMP dual-device hot backup in a VRRP master/backup scenario.

Pre-configuration Tasks

Before configuring IGMP dual-device hot backup in a VRRP master/backup scenario, complete the following tasks:

  • Assign IP addresses to loopback interfaces on the master and backup devices, and configure a routing protocol.
  • Configure mVRRP and common VRRP backup groups.

Configuration Procedures

Figure 3-5 Flowchart for configuring IGMP dual-device hot backup in a VRRP master/backup scenario

Configuring a Dual-Device Backup Platform

This section describes how to configure a dual-device backup platform to back up IGMP entries. If a network node or link fails, a rapid multicast service switchover is triggered, improving service reliability.

Prerequisites

A VRRP backup group has been created using the vrrp vrid virtual-router-id [ virtual-ip virtual-address ] command.

An mVRRP backup group has been created using the admin-vrrp vrid virtual-router-id [ ignore-if-down ] command.

Context

In a VRRP master/backup scenario, a dual-device backup platform enables the master device to back up IGMP entries to the backup device through a remote backup service (RBS) channel, ensuring multicast service continuity. Configuring a dual-device backup platform includes configuring an RBS, a remote backup profile (RBP), and a dual-device VRRP backup platform.

Perform the following steps on both the master and backup devices:

Procedure

  1. Configure an RBS.
    1. Run system-view

      The system view is displayed.

    2. Run remote-backup-service service-name

      An RBS is created, and the RBS view is displayed.

    3. Run peer peer-ip-address source source-ip-address port port-id

      TCP connection parameters are set for the RBS.

      peer-ip-address specifies the IP address of the peer device in a VRRP backup group, and source-ip-address specifies the IP address of the local device in the VRRP backup group. The IP addresses of the master and backup devices must have been configured on their own interfaces, sub-interfaces, or logical interfaces (such as loopback interfaces) and be able to ping each other.

      port-id specifies a TCP port number. The TCP port numbers configured on the master and backup devices must be the same.

    4. Run quit

      Return to the system view.

  2. Configure an RBP.
    1. Run remote-backup-profile profile-name

      An RBP is created, and the RBP view is displayed.

    2. Run backup-id backup-id remote-backup-service service-name

      A backup ID is set for the RBP, and the RBP is associated with a specified RBS.

      backup-id specifies a backup ID for an RBP. You can use a backup ID and an RBS to determine an RBP. The backup IDs configured for the same RBP must be the same on the master and backup devices and can no longer be configured for other RBPs.

    3. Run peer-backup hot

      Hot backup is configured for user information backup between the master and backup devices.

    4. Run quit

      Return to the system view.

  3. Configure a dual-device VRRP backup platform.
    1. Run remote-backup-profile profile-name

      An RBP is created, and the RBP view is displayed.

    2. Run vrrp-id vrid interface interface-type interface-number

      The ID and interface of a VRRP backup group are associated with the RBP.

    3. Run quit

      Return to the system view.

    4. Run commit

      The configuration is committed.

  4. Configure rapid service link switching.
    1. Run monitor-group monitor-group-name

      An interface monitoring group is created, and the group view is displayed.

    2. Run monitor enable

      The monitoring function is enabled for the interface monitoring group.

    3. Run binding interface

      The interface to be monitored is added to the interface monitoring group.

    4. Run quit

      Return to the system view.

    5. Run multicast routing-enable

      IP multicast routing is enabled.

    6. Run interface interface-type interface-number

      The interface view is displayed.

    7. Run pim sm

      PIM-SM is enabled on the interface.

    8. Run igmp enable

      IGMP is enabled.

    9. (On the interface that connects the master and backup devices) Run vrrp vrid virtual-router-id track monitor-group [ monitor-group-name ] failure-ratio failure-ratio-value [ link | [ reduced priority-value ] ]

      The mVRRP backup group is enabled to track the interface monitoring group.

    10. (On the interface that connects to a downstream device) Run vrrp vrid virtual-router-id1 track admin-vrrp interface interface-type interface-number vrid virtual-router-id2

      The common VRRP backup group is bound to the mVRRP backup group in flowdown mode.

    11. (On the interface that connects to a downstream device) Run multicast track vrrp vrid vrid-value

      The multicast service interface is bound to the VRRP backup group.

    12. (On the interface that connects to a downstream device) Run pim ignore dr-state

      The interface is enabled to ignore the PIM DR state.

    13. (On the interface that connects to a downstream device) Run pim ignore assert-state

      The interface is enabled to ignore the PIM Assert state.

    14. (On the interface that connects to a downstream device) Run remote-backup-profile profile-name

      The interface is bound to the RBP.

    15. (On the interface that connects to a downstream device) Run quit

      Return to the system view.

    16. (Optional) Run multicast rui enhancement protocol port

      A UDP port number is set for dual-device hot backup enhancement.

    17. Run commit

      The configuration is committed.

Enabling Remote Backup for IGMP

This section describes how to enable remote backup for IGMP to implement IGMP entry consistency between the master and backup devices.

Context

In a master/backup E-Trunk scenario, IGMP dual-device hot backup enables IGMP entry backup between the master and backup devices through a remote backup service (RBS) channel, ensuring multicast service continuity. To enable IGMP dual-device hot backup to take effect, you must enable remote backup for IGMP.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run remote-backup-profile profile-name

    An RBP is created, and the RBP view is displayed.

  3. Run service-type igmp

    Remote backup is enabled for IGMP.

  4. Run commit

    The configuration is committed.

Verifying the Configuration of IGMP Dual-Device Hot Backup

After configuring IGMP dual-device hot backup, verify the configuration.

Prerequisites

IGMP dual-device hot backup has been configured.

Procedure

  • Run the display remote-backup-profile [ profile-name ] command to check information about RBPs.
  • Run the display remote-backup-service [ service-name [ verbose ] ] command to check information about RBSs.
  • Run the display multicast rui [ vpn vpn-name ] source-address source-address group-address group-address eth-trunk eth-trunk-id command to check whether a specified Eth-Trunk interface can forward the traffic of a specified multicast group.

Example

Run the display remote-backup-profile profile-name command to view information about a specified RBP.
