Scenario - Two core switches (cat 6509's) and various access switches (cat. 2950g's). The accesss switches are dual homed to each core switch.
The 2950's are in stacks of 2 or 3 with stacking gbics. i.e. A connected to B and B to C and a redundant connection between A and C. A and C also have an uplink to the cores. The stacks are not clustered.
If I deploy CSUP do I need to remove the redundant A to C link in order to endure FAST failover if a primary uplink fails?
Code is not new enough to support RSTP / MSTP
