I am trying to find out the best way to run spanning-tree in a service provider network. Right now we are running pvst and setting spanning-tree bpdufilter enable on all ports. It seems to me like this is disabling spanning-tree all together. Is this dangerous and what should I be doing? We are using Cisco 3550's.
as per my experience one should go with the mst with the default instance becasue pvst has limitation of 128 but mst doesnot have. BPDu filter should use on the switch where your access swicthes are termination, the main advantage of the command is that if the port is receiving superior or inferior BPDU it will simply ignore the BPDU. its a BCP to use on access ports.
