  • A No valid flex-algo definitions, because of the conflicting parameters.
  • B One valid flex-algo definition, using delay as the link metric and including green links.
  • C One valid flex-algo definition, using te-metric as the link metric and including blue links.
  • D Two valid flex-algo definitions, one uses te-metric as the link metric and includes blue links and the other uses delay as the link metric and includes green links.
Explanation

For a given Flex-Algo identifier, routers select one winning Flexible Algorithm Definition when advertisements conflict. The advertisement with the highest priority wins. Flex-Algo 129 advertised by R10 has priority 500, which supersedes R1's priority 200; its definition uses the delay metric and includes links in the green administrative group.
