a few years ago I
installed a point-to-point bridge with two 7731 antennas, now the client
asked me to create an additional bridge to be backed up to the existing
one and we made it with two P300s. The client has
configured the spanning tree protocol on the Catalyst switches to have
the possibility to connect both bridges without creating loops on the
network, but once the second radio link is connected, after a few
minutes one of the two bridges goes down. How can I
make a physical operation of the two bridges at the same time having
one in backup to another without creating loops on the network?
