Configuration Guide
After the prejoin function is enabled, if the upper-layer multicast router does not support static
multicast entry forwarding, you need to enable the unsolicited report function of IGMP packets
so that the user can request for the program quickly. Generally, the upper-layer multicast router
processes the user request by responding to the group-specific query and the general query.

Run the igmp program add ip ip-addr prejoin enable command to enable the program prejoin
function.

l Run the igmp unsolicited-report interval command to change the interval of the unsolicited
Step 3 Check whether the prejoin function is configured correctly.
