Redistribution Notes – Tagging

  • Tagging provides a way to mark common or similar routes to manipulate later.
  • In redistribution scenarios with mutual redistribution on two different routers, any routes that gets redistributed from one route process to another are tagged.
    • When the other router sees those tags on the route, that route to keep from adding non-optimal routes to its routing table.
  • Tags can also be used to do other manipulation such as setting higher metrics or changing ADs.
