In a data center, when multiple routing/service nodes are providing single active redundancy for a set of L2, L3 and/or L4-L7 services. Both non-revertive and revertive fail over modes are required for the services. This draft describes a method to achieve the non-revertive and revertive fail over modes for services using Bidirectional Forwarding Detection (BFD).
