摘要
A first packet forwarding device is able to form a redundancy group with another packet forwarding device, and is configured to switch master and backup operation with the another packet forwarding device in a complementary manner. The first packet forwarding device is further configured to switch a first operation mode and a second operation mode in the backup operation, the first operation mode monitoring a control packet transmitted regarding the redundancy group from the another packet forwarding device that performs the master operation, and the second operation mode not monitoring the control packet. A proxy device is configured to monitor the control packet on behalf of the first packet forwarding device when the first packet forwarding device is in the second operation mode, and to control switching between the first and second operation modes of the first packet forwarding device based on monitor result of the control packet.
