I have huge layer 2 network around 350+ workstation.
In my network i have 10 access layer 2948 switches directely connected to layer 3 switches. When ever any problem in the lan ( incease of stp loop) all link HSRP instance in layer 3 flapping.
is that right way of design. any other idea to contain this layer 2 issue. though i have enabled portfast and loopgurad and root gurad.
still i need to some more help to contain this layer 2 failure.
