Hi,
We have two data centers, each has a pair of S4810's connected together via VLT, in each DC the top switch as a RSTP priority of 4096 and the bottom 8192, so far so good, VLT is happy :)
There is now a business requirement to connect the two DCs together via a L2 sudo-wire so that one VLAN can be stretched across the two DCs. This is because and application needs to fail over for DR and CAN'T be re-ip'ed
What will happen when the connection is made? We need each DC to have a root bridge.
Is there any way to disable RSTP, MSTi PVST on the interface where the sudo-wire will be connected, as there is no way a L2 loop can happen as the DCs are geographically separate.
We are not looking to achieve rooted VLT etc, the objective is to just stretch a single VLAN over and L2 link.
Hope this makes sense and someone can help please?
