I have a topology in which there is a main ring and some nodes in the main ring have a minor ring. 1- which STP configuration has the fastest convergence time? How would you configure spanning tree for all switches? I think RSTP does the best, but Is there any other configuration to help convergence time?
2 - Does RSTP have any limitation? limitation In number of switches for instance? or incompatibility with other vendor's RSTP or spanning tree algorithm?
3- Is RSTP practical solution for this topology with a large number of switches? 45 switches as the main ring and more than 100 switches in minor rings?
4- Is there any other faster way, rather than spanning tree, to provide protection for this large network?
Thank you all!
