I'm currently trying to set up a connection from a Datacenter to a HQ using 2x Layer 2 connections.
There are 2 Procurves on one side and 2 on the other, each is connected to 1 of the Layer 2 Links. Basically I have a ring of 4 Switches.
I have to monitor the Layer 2 connections using IP addresses on the Switches. This means for example Switch 1 in HQ has an IP address in VLAN 99, this IP address has to be reachable using the Main-Layer 2 Link but should be unreachable over the backup Layer 2 Link even if the Main-Link goes down.
Same for the Switch 2 in HQ: IP in vlan 100 of Switch 2 should be reachable over backup but not over main.
For all Data-VLANs the backup-Layer2-Link must have the blocking Port of MSTP.
Is this configuration possible using 3 Instances (Monitor-Main, Monitor-Backup, Data)? I know the MSTP VLAN Config must be identical on all Switches, but would it work to simply not use VLAN 99 on Switch 2 (or not allow it on the Link to Switch 1) in this example?
