#11043: 642 813 exams Gets a little bit confusing -------------------------+------------------------------ Reporter: manjammehta | Owner: nobody Type: bug | Status: new Priority: normal | Milestone: R1 Component: - General | Version: R1/Development Keywords: 642-813 | Blocked By: Blocking: | Has a Patch: 0 Platform: All | -------------------------+------------------------------ You look at simply the show spanning tree says that the spanning tree protocol is an able the type a protocol is IEEE this means that we're running a protocol that is compatible with the standard of spanning tree because these any these numbers that start with the are 80 to use these are defined by the other IEEE organization like in thecae of either net even as defined by 80 2.3 then you'll see there's sub specifications like Gigabit Ethernet would be 80 2.3 Z or in this case there's I 8.o 2.1 D is talking about internet but it's not mad spanning tree for Africa internet so this PST this is what the Cisco switches run as the defaults there's two other versions that are known as rapid spanning tree protocol and multiple spanning tree protocol sometimes this is MST or sometimes MSTP these two you form the new standard and the idea behind these two is that they took a lot of the are the custom changes that Cisco made to the purview man spanning tree and then a didn't into a standardized [http://642-813dump.com/ 642-813] protocol so if you have a Cisco switch and then you have onerous to switch or some other vendor you technically can run the new enhancements because they're now defined by the other standards so the original common spanning tree the the rapid spanning tree and the multiple spanning tree these ones are standards the PTSD plus this is the Cisco version other now the overall idea the protocol is that we're going to build the network as if it was area a tree you're a hierarchy were at the top of the tree we have what is known as the root bridge and the rib ridge's is basically reference point for everyone else to figure out how should I send my traffic through the network ultimately what you would see is that when switches forward traffic between each other they're going to have to send it some way towards the bird bridge before can be delivered to other switches so if we have a case here where we have a number of switches even though the physical connections between them may not look like this we may have other redundant paths like the link between five and seven where between four and six or between3&6 but. http://642-813dump.com/ -- Ticket URL: <https://dev.haiku-os.org/ticket/11043> Haiku <https://dev.haiku-os.org> Haiku - the operating system.
