Our network is basically a star topology. There are 2 ways a building connects to the core.
Way #1:
The core switch has 1link each to 2 distribution switches in a buiding.
In the various buildings the distribution switches have single links up to
the switches on the floors. dist-a has a single link to floor-1a, dist-b has
a single link to floor -1b, etc. floor-1a and floor-1b are directly connected.
Repeat for floor-2a, 2b, etc. dist-a and dist-b are directly connected.
Way #2:
The core switch has a single link to a single distribution switch in a building closet.
The switches on the other floors are connected to the distribution
switch with a single link. No interconnections. Here there is a single point of failure at the distribution switch.
STP is not running consistently everywhere. On the core switch stp is running.
On the dist switches in 2 buildings it is running. It is not running on another
dist switch. In some cases stp is not running on vlan 1 but is running on
other vlans. It doesn't seem to matter if it is a location that has redundant connectivity or not
Things seem to be working fine. No weirdness. And part of me is thinking
if it's not broken don't fix it. But at the same time, it seems like consistency
would be a good thing.
Anyone have any thoughts on this one way or another? Any reasont NOT
to implement stp? Any suggestion as to how to approach documenting
things or a 'migration plan'?
Thanks in advance.
