RSTP conergence


(Sherif T) #1

Hi,
According to Cisco RSTP documentation:

“In RSTP, only non-edge ports that move to the forwarding state cause a topology change. This means that a loss of connectivity is not considered as a topology change any more, contrary to 802.1D (that is, a port that moves to blocking no longer generates a TC”

Can someone explain why a link failure is not considered a Topology change? How would link failures are detected by RSTP and what is their impact?

Thanks!
