Abstract: A VRRP fault detection method is applied to a VRRP group including one primary router and one or more secondary routers. The method includes: sending, by the primary router and the secondary router, link detection packets having an echo response function, where a destination address of the link detection packet is a virtual address of the VRRP group. The method also includes determining, by the primary router and the secondary router, whether response packets corresponding to the link detection packets sent by the primary router and the secondary router are received within a predetermined time, and if the primary router and/or the secondary router does not receive the response packet within the predetermined time, determining that the primary router is faulty.

Abstract: A gateway receives a link state packet (LSP) that includes a network identifier of a Layer 2 virtual network and a multicast address and that is sent by each routing bridge (RB) that is on the Transparent Interconnection of Lots of Links (TRILL) network; separately performs calculation on the network identifier and the multicast address that are in each LSP, to obtain a calculation result corresponding to each combination of the network identifier and the multicast address; if the gateway determines that information preconfigured on the gateway matches a calculation result corresponding to a combination of the network identifier and the multicast address, sends a notification message including the network identifier and the multicast address that are in the matched combination to each RB; receives from at least one RB, a multicast packet corresponding to the multicast address in the matched combination, and forwards the multicast packet.
