UplinkFast over network with only four 2950

I Have 4 switches 2950 connected each one with the others three and one of them as a root.

1.- Can I activate UplinkFast in order to provide fast convergence in the network access layer after a spanning tree topology change?

2.- Should I activate UplinkFast only on the three wich are not the root?

3.- Can I have problems with this configuration (in terms of uncontrolled loop)

4.- What happen if the root switch is going down? IN that case one of the other three switches with UplinkFast enabled will be the new root.

Re: UplinkFast over network with only four 2950

This is not the recommanded us of uplinkfast, but I don't you will have any problems. Use RSTP (802.1w) instead - it supported by the 2950 - then you will get fast convergence.
