Abstract
A method for implementing redundancy protection applied in a first router includes: providing a first protection group comprising one active interface and any number of inactive interfaces selected from interfaces of the first router, wherein all interfaces in the first protection group serve to distribute or receive multicast traffic; activating Bidirectional Forwarding Detection BFD protocol only at the active interface in the first protection group, so as to enable the active interface in the first protection group to establish interaction with an active interface in a second protection, wherein a second router determines a status of the active interface in the first protection group through the active interface in the second protection group; and stopping all interfaces in the first protection group to distribute or receive the multicast traffic when failure occurs at the active interface in the first protection group.
