62-5 enable mld_snooping
Description
This command is used to enable MLD snooping on the Switch. The forward_mcrouter_only
function is disabled by default. The enable mld_snooping forward_mcrouter_only command will
enable the MLD snooping function and the forward multicast router only function.
If forward multicast router only is enabled, the Switch will forward all multicast traffic to the
multicast router, only. Otherwise, the Switch forwards all multicast traffic to any IP router.
