I am experimenting STP in a lab and got confused by the output of the show spanningtree command on the second switch. I have the 2 switches connected via Gig interfaces and have VLANs on both switches configured. The output from SW1 is clear but not the one from SW2. In the output, it shows on VLAN1 and VLAN51 different MAC addresses on the Priority Root ID and Bridge ID and I am confused as why these two MAC addresses are different. The second thing I am confused about is VLAN39 which says âThis is the rootâ where the other switch is the Root Bridge!!! Attached are the two outputs from both switches.
Thanks in advance,
