My network is in a state of migration from PVST to MSTP. The network has Cisco, Huawei and ZTE switches in the amount of 50 pieces and about 500 computers. In connection with this, questions arise about the MSTP.
The network has VLANs from 1 to 100. VLANs are common to all switches. I want to divide the network into two regions of the MST, but VLANs will remain the same. For example, VLAN 2 in the MST region 1 instance 1 is the same VLAN 2 in region 2 instance 1. I put together a test version and everything works, i.e. despite the fact that computers in different regions of the MST, they work as if nothing had changed for them. This is normal? So it should be? I could not find information on this topic: everywhere in the examples they use different VLANs in different MST regions.
And one more question: can I leave the revision equal to 0 (so by default) in all configurations of the MSTP?
- the whole network, this is the L2 network;
- the network has an L3 switch that is used to route packets between VLANs;
- most of the switches after the upgrade are ZTE switches;
- it is planned to replace PVST with MSTP for faster convergence in the presence of changes in the network;
- also with the help of MSTP it is possible to balance the load on the channels, in case this need arises;
- does it make sense to divide the network into two regions of the MST so that changes in the regions do not affect each other?
