Abstract
A method and switch for Internet Group Management Protocol (IGMP) snooping are disclosed. The method includes: configuring, by a switch, a router interface listed in an IGMP snooping table; configuring, by the switch, a multicast forwarding table entry and a corresponding outgoing interface list; and configuring, by the switch, interfaces which are adjacent to switches in the outgoing interface list. The advantage of the invention is the rapid recovery of the multicast data packets forwarding in the loop network when the network topology of the Layer Two loop network changes.
Claims11
A method for implementing Internet Group Management Protocol, IGMP snooping, comprising:
- configuring, by a switch, a router interface listed in an IGMP snooping table;
- configuring, by the switch, a multicast forwarding table entry and a corresponding outgoing interface list;
- and
- configuring, by the switch, interfaces which are adjacent to switches in the outgoing interface list.
A switch for implementing Internet Group Management Protocol, IGMP snooping, comprising:
- a storage unit, adapted to store a multicast forwarding table entry including an outgoing interface list, and an IGMP snooping table;
- an interface query unit, adapted to query interfaces which are connected to neighboring switches;
- and
- a central processing unit, adapted to establish the multicast forwarding table entry and a corresponding outgoing interface list according to a received IGMP member report message, and to add router interfaces to the IGMP snooping table according to an IGMP query message.
