Question:
Which step in the link-state routing process is described by a router sending Hello packets out all of the OSPF-enabled interfaces?
- electing the designated router
- establishing neighbor adjacencies
- injecting the default route
- exchanging link-state advertisements
Explanation: OSPF-enabled routers must recognize each other on the network before they can share information. An OSPF-enabled router sends Hello packets out all OSPF-enabled interfaces to determine if neighbors are present on those links. If a neighbor is present, the OSPF-enabled router attempts to establish a neighbor adjacency with that neighbor.
