PAgP and STP
Just read something in the LAN Switching book (page 273) and wanna double check if my understanding is correct.
If a group of links is configured using PAgP "ON" then only one link (which one?!!) will be used for STP and there is no fault tolerance in terms of STP messaging.
Does it mean the other mode (e.g. desirable) would lead to a STP-over-multi link situation?
