RuggedRouter™ User Guide

GOOSE Packets received from the network are stripped of their network headers and forwarded to Ethernet ports configured for the same multicast address. The forwarded frames contain the MAC source address or the originating device, and not that of the transmitting interface. The VLAN used will be that programmed locally for the interface and may differ from the original VLAN. The frame will be transmitted with the highest 802.1p priority level (p4).

Packets received from the network will also be forwarded to any other remote daemons included in the group.

Note: Avoid network configurations where the daemons can form a traffic loop. The simplest such configuration is a triangle network where each daemon forwards to two other routers. Frames arriving at one router will start cycling in clockwise and counterclockwise directions.

To avoid such “GOOSE storms”, frames forwarded to the network are tagged with an initial time to live count. The count is decremented at each relay to the network and prevents the frame from being relayed indefinitely.
