ETHERNET VIRTUAL PRIVATE NETWORK FAST REROUTE TRIGGERED DESIGNATED FORWARDER ELECTION

Abstract: a mechanism that allows ce-to-pe traffic to achieve minimal traffic loss at the same rate as pe-to-ce redirection (frr). the solution relies on a fast-unblocking of the backup-df interface based on appearance of redirected packets from the active df-elected peer. a slow-path confirmation mechanism is included to further mitigate false-positives, as well as maintaining data plane and control plane in sync.
