I want to implement a backup link between switches without enabling STP. I'm looking for something similar to Flex Links, but, to use Flex Links, the 2960 switch must be running the LAN Base Image, and the switches that I want to configure are running the LAN Lite Image.
Do you know something similar to Flex Links that I can use with Catalyst 2960 Lan Lite image switches?
Because the backup path will be connected to a 1300 wireless bridge. I've atthached a picture with the topology.
I don't wan to use STP because I want to avoid that, due to a topology change, the STP blocks the Switch B port that is connected to the AP-B. If this port is blocked, Switch D will lost the connection too.
AP-B treats those two bridge links as two separate VirtualDot11 interfaces each with its own STP state. Depending on which switch is a root bridge, you can get AP-B in AP-C in blocking state, and all other paths in forwarding. If you make switch A a root bridge and all wired links are the same cost, you'd have AP-B or AP-C block that APB-APC link, and APB-APD would be forwarding.
In this case, when the gigabitethernet01 (the active link) goes down, the gigabitethernet0/2 will forward traffic. But, when the active link goes up again, it will not preempt the backup link (the backup link will forward traffic until it fails).
