Election Process In Stp

It is important to understand the information these bpdus carry as it will help understand the election process itself.

Election process in stp. 1 st step selects a root bridge how. Election procedure all the switches in the network declare themselves root bridge and start exchanging their own bpdu. Firstly spanning tree protocol stp is.

Simply a way to create a logical loop free network in our lan by blocking s. The election process uses several stp messages sent between switches which help each switch to decide who is the root bridge. 2 byte priority field by default all switches have the priority of 32768.

Lower bridge id is preffered. This value can be changed using configuration commands. Each switch that participates in stp will have a 8 byte switch id that comprises of the following fields.

By selecting the bridge id lowest is better. Bridge id is of 8byte. Cisco ccna spanning tree protocol root bridge root designated blocked ports.

Rootbridge election process in stp enabled environment 21 03 2020 28 06 2020 milan ciljak in redundant l2 topology stp ensures loop free path for frames traveling among endpoints blocking redundant paths that cause a loop. These messages are called hello bpdu where bpdu stands for bridge protocol data unit. Spanning tree protocol a network protocol that ensures loop free topology.

Posted on october 1 2017 september 29 2019 by loopy this is an example of stp doing what it does best and that is putting the amber lit port 2 in blocking state to prevent a switching loop from forming. Spanning tree election how does stp works. The bpdu with the lowest bridge i d will be considered as superior.
