Enabling IPv6 multicast source port filtering

About IPv6 multicast source port filtering

This feature enables the Layer 2 device to discard all IPv6 multicast data packets and to accept IPv6 multicast protocol packets. You can enable this feature on ports that connect to only IPv6 multicast receivers.

The configuration made in MLD-snooping view has the same priority over the interface-specific configuration.

Restrictions and guidelines

When IPv6 multicast source port filtering is enabled, the device automatically enables IPv4 multicast source port filtering.

The configuration made in MLD-snooping view has the same priority as the interface-specific configuration, and the most recent configuration takes effect.

Enabling IPv6 multicast source port filtering in MLD-snooping view

  1. Enter system view.

    system-view

  2. Enter MLD-snooping view.

    mld-snooping

  3. Enable IPv6 multicast source port filtering globally.

    source-deny port interface-list

    By default, IPv6 multicast source port filtering is disabled globally.

Enabling IPv6 multicast source port filtering in interface view

  1. Enter system view.

    system-view

  2. Enter Layer 2 Ethernet interface view.

    interface interface-type interface-number

  3. Enable IPv6 multicast source port filtering on the port.

    mld-snooping source-deny

    By default, IPv6 multicast source port filtering is disabled on a port.
