Hi Team,
I have a core switch 4600 and a EX 2200 Connected to it as trunk, I am running vstp and core is set to bridge pririty of 4k,
the ex switch prioruty was set to 16 K, but Still I see EX 2200 spanning tree as the root bridge , not the core switch ? I was thinking that the EX should be having the roodbidge of Core.
* Note there is only one trunk connected between EX 4600 and EX 2200.
* I have only shown a vlan due to space limitation
ON EX 2200
