Ethernet virtual private network fast reroute triggered designated forwarder election
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.
