Resilient Ethernet Protocol

By Terry Slattery

I became aware of the Resilient Ethernet Protocol (REP) a few weeks ago and have been reading about it. The Cisco documents position it as a replacement for the Spanning Tree Protocol (STP). The documentation says that it can fail over in 50ms, which is certainly impressive, but then says that in some cases it can take up to 250ms to fail over without specifying the conditions in which this may occur.
