Animated GIF showing an 802.1aq network with a 7 member E-LAN using ISID 100 for both transmit and receive. The tree from each member to each other member is shown in sequence. A small purple V indicates the source in each case and a short pause emphasizes the symmetry of routing between nodes 35 and 40 with an extra red line.
