Abstract
Exemplary methods include generating a first fast reroute (FRR) next hop (NH) comprising of a first primary next hop (PNH), a first secondary next hop (SNH), and a first attribute, wherein the first PNH and first SNH include forwarding information that causes traffic to be forwarded towards a second and third network device, respectively. The methods include sending a first request to a forwarding plane to generate a second FRR NH comprising of a second PNH, a second SNH, and a second attribute. The methods include updating contents of the first FRR NH, and sending a second request to the forwarding plane to update the second FRR NH, wherein the second request causes the forwarding plane to determine whether to revert back to using the second PNH based on whether the first attribute included in the second request is different from the second attribute of the second FRR NH.
