Parameters

count: Specifies an MLD querier's robustness variable in the range of 1 to 255.

Usage guidelines

The MLD querier's robustness variable defines the number of times to retransmit MLD queries if packet loss occurs. A higher robustness variable makes the MLD querier more robust, but it increases the timeout time for IPv6 multicast groups.

You can set the MLD querier's robustness variable globally for all interfaces in MLD view or for an interface in interface view. For an interface, the interface-specific configuration takes priority over the global configuration.

Examples

# Set the global MLD querier's robustness variable to 5 on the public network.

<Sysname> system-view
[Sysname] mld
[Sysname-mld] robust-count 5
