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.

Presented herein is an exemplified system and method that implicit aliasing in an EVPN network having provider edge nodes in a network infrastructure (e.g., a MPLS infrastructure). In particular, the exemplified system and method employ a Border Gateway Protocol (BGP) based EVPN construct that facilitates multiplexing across large number of different physical interfaces, among multiple device manufacturers and vendors, while providing implicit antialiasing functionality, and being fully supportive of EVPN capabilities. In an embodiment, a method is disclosed that joins the reachability information from a first network device and a second network device, in response to receiving a first EVPN advertisement from the first network device and receiving a second EVPN advertisement from the second network device, such that traffic later transmitted in associated with the first EVI or the first ESI are routable to both the first network device and the second network device.
