I'm trying to understand RSPT and I had setup a small network lab with 4 Catalyst access switches. I provide a small schema of my lab setup. I wrote on the schema where I was expected and see root port, designated and alternated port.
But when I disconnect a topology change I see the topology converge very quickly. When I reconnect previously disconnected cables the spanning tree algorithm does not reconverge correctly and each tine I see 1 port place in error disable stateâ¦. I should each time reenable port manually to make spanning tree return to his original topology.
At the first time I was setup each connection with etherchannel configuration, because I was have some problems to my topology reconvergence after returning to originale state, I decide to connect one one cable in each etherchannel (avoiding problem with etherchannel it-self ) but same thing appendâ¦
you will probably have to post the configs . The err-disable part is probably a etherchannel problem where both sides of the channel do not have equal settings so the switch puts it in a err-disable state.
here I attached the output of the following command :
sh cdp nei detail
sh int status
Like I had tell in previous post only one ethernet cable on each etherchannel (make the etherchannel a virtual link contain only one physical connection) I was would like to removed etherchannel issues from my problems
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
