- Blue, 1500 points or more
Cisco documentation says that trunks (802.1q as well as ISL) are point-to-point connecitons and I already found a discussion about that:
We have a similar request by our customer which want to use layer-2 crypto boxes in a so called point-to-multipoint mode in order to connect 2 sites redundantly and cryptographically secured.
Each of our switches will have a (p2p) connection to one crypto box and all of the boxes together act like a single switch, in other words: We have something like a single LAN connecting our Switches.
Actually we're still in the planning phase and discussing the use of tagged frames to be more flexible in case of changing demands.
I can't think of a reason why this shouldn't work. Of couse we will run full duplex mode and fixed configuration (no DTP).
Am I overlooking something?
