WebbIntroduction It is important to understand which Traffic Engineering (TE) links in a given network might be at risk from the same failures. In this sense, a set of links can constitute a Shared Risk Link Group (SRLG) if they share a resource whose failure can affect all links in the set [ RFC4202 ]. WebbShared risk link groups (SRLGs) have been defined and implemented in many network planning tools and routing protocols. A single SRLG represents one potential failure, and …
