I am seeing that there are many options for spanning tree type, is that correct?
RSTP Link and Edge Types
Link-Type point-to-point: Links between switches
Edge-Type point-to-point: Link between switch/end user
Link-Type Shared: Link between switch and a hub
where does porftfast come in? is there anything else that we need?
Someone told us about uplinkfast and backbone option in spanning for fast convergence... any idea about that?
this what we are using... is that the latest and greatest?
spanning-tree mode pvst
no spanning-tree optimize bpdu transmission
portfast is applied to ports that have end user devices connected that will not be running STP eg. PCs/server/printers etc.
the functionality of uplinkfast and backbone have been incorporated into RSTP so you do not need to manually configure them.
All interconnects between switches should be defined as P2P as should edge device ports to PCs etc. This is what allows RSTP to converge so much more quickly than standard STP. Ideally you should not have any shared links as this means RSTP would need to revert to STP timers.
RSTP and MST are the types of STP now generally used. MST actually uses RSTP anyway so you will be fine using RSTP.
It is recommended to manually set the root and secondary root bridges in your network, usually these being the main distribution or core switches, basically the switches that are also responsible for inter-vlan routing.
