Sending Query Messages upon Network Topology Change

Sending Query Messages upon Network Topology Change

Context

When the topology of a Layer 2 network changes, forwarding paths of multicast packets may change. You can configure the switch to send MLD Query messages upon link failures. When the switch receives MLD Report messages from group members, it updates member port information according to messages. This enables multicast traffic to be quickly switched to new forwarding paths.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    mld-snooping send-query enable

    The switch is configured to send MLD General Query messages when network topology changes.

    By default, the switch does not send MLD General Query messages when network typology changes.

    This command enables the switch to detect Layer 2 network topology changes and send MLD General Query messages. The switch can then quickly update group member port information to prevent interruption of multicast data forwarding.

  3. (Optional) Run:

    mld-snooping send-query source-address ipv6-address

    The source IPv6 address of the MLD General Query message is configured.

    By default, the source IPv6 address of MLD General Query messages is a link local address, an IPv6 address starting with FE80::. If another device on the network is using the default source IPv6 address, run this command to change the source IP address.
