Parameters

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

Usage guidelines

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

You can set the IGMP querier's robustness variable globally for all interfaces in IGMP 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 IGMP querier's robustness variable to 5 on the public network.

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