MLD Poker - A small utility that pokes sleepy devices for MLD Reports
Usage: mldpoker IFNAME
IFNAME: A bridge port interface, with the following properties:
- The bridge on top of it needs to have multicast_snooping enabled
- The bridge on top of it needs to have multicast_querier enabled
- The bridge on top of it needs to have a valid IPv6 link-local address
If a host behind IFNAME newly appeared or was unresponsive for at least 15 seconds and now reappeared then MLD Poker sends a general MLDv1 Query with an MLD Maximum Query Response Delay of 0 to it (request for an immediate, undelayed MLD Report). The MLD Query is sent to the target host directly via its unicast MAC address.
