Friends, when I have a network with:
1 CISCO Catalyst 3750-E (core root bridge) (Flex Uplink)
1 DELL (user network) (Connecting Edge Switches)
1 IBM Flex (network servers)
What would be the best STP for communicating between the three?
Should the 3 switch work on the same protocol?
Today a configuration looks like this:
Cisco / Flex: pvst
Whenever I connect something new does not swithcs the dell try to assume as root, and I have a blink in the network.
In that case if putting Dell as PVST will solve my problem?
I would use the same stp type alright through the network to make it easier to maintain/tshoot anyway , mixing stp types can get bit messy but pvst and rstp should be interoperable and work ok together but you wont get all the enhancements of rstp when pvst is in place too so you may have another issue there with your config rather than interoperability of vendors and stp types
Well, pvst and rstp should not have incompatibility in the communication.
What is affecting me is the drop in the network when I plug in something else on the switch where apparently it tries to elect another swtich as root.
