I received one of the virl switch images and was building a lab testing spanning tree. Can you tell me what is the difference between the commands listed below:
#spanning-tree portfast edge #spanning-tree portfast network #spanning-tree normal
and when should you use which one? Also i read the lessons on both spanning-tree uplinkfast and spanning-tree backbonefast. Both commands seem to do the same thing , fast convergence if a link or indirect link fails. Maybe i am not understanding the lessons. Is there a preference in using one over the other? Can both commands be enabled at the same time on a switch?
