摘要:
Systems and methods for Segment Routing Traffic Engineering (SR-TE) with awareness of local protection include the advertisement of local protection information in effect at each SR capable node via Interior Gateway Protocol (IGP), Border Gateway Protocol Link-State advertisement (BGP-LS), telemetry, etc. A method includes determining local protection in effect at a node in a Segment Routing network; and advertising information based on the local protection via extensions in a routing protocol, e.g., IGP, BGP-LS, etc., associated with the Segment Routing network, wherein the information includes identity of protected elements and a type of the local protection.
