A service provider configures an SR-TE policy on an IOS-XR head-end toward endpoint 10.0.0.9 with color 100. Three candidate paths are defined for this policy: a BGP-signaled path with preference 200, a PCE-computed path with preference 150, and a locally configured explicit path with preference 250. All three candidate paths are currently valid (their SID lists resolve). Which candidate path will the head-end install and use to forward traffic for this SR-TE policy?
