26. Configuring Layer 2 Tunnels
Revision 1.14.3 236 RX1000/RX1100™
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 “packet 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.
