What function is performed by the OSPF designated router?

  • summarizing routes between areas
  • dissemination of LSAs
  • maintaining the link-state database
  • redistribution of external routes into OSPF

Explanation: OSPF designated routers are elected on multiaccess networks to disseminate LSAs to other OSPF routers. By having a single router disseminate LSAs, the exchanging of LSAs is more efficient.
