Hello,
After reading a bit BCMSN (Building Cisco Multilayer Switched Networks), I was presented with the following diagram:
Switch Block 1 Switch Block 2
Access Sw1 Access Sw2 Access Sw1 Access Sw2
... ...
Access Swn Access Swn Access Swn Access Swn
| | | |
| | | |
Distrubution Sw1 Dist Sw2 DistSw1 DistSw2
| | | |
| | | |
\ \ / \ / \ / | \ | \
CORE SW1 (no conn betw Core Sw) CORE SW2
The scenario is quite forward, in both blocks, access switches are connected to distrubution switches with redundant uplinks using STP. And distrubition switches are connected to both core switches. Nevertheless, the book says if Core Switches are connected to each other a STP bridging loop might occur.
Can anyone please explain me how could this happen?
Best regards,
