1.3.7 Check Your Understanding – OSPF Operation Answers

1. During this OSPF state on multiaccess networks, the routers elect a Designated Router (DR) and a Backup Designated Router (BDR).

  • Down State
  • Init State
  • Two-Way State
  • ExStart State
  • Exchange State
  • Loading State
  • Full State

Explanation: In the Two-Way State on multiaccess networks, the routers elect a Designated Router (DR) and a Backup Designated Router (BDR).

2. During this OSPF state, routers send each other DBD packets.

  • Down State
  • Init State
  • Two-Way State
  • ExStart State
  • Exchange State
  • Loading State
  • Full State

Explanation: In the Exchange State, routers send each other DBD packets.

3. An OSPF router enters this state when it has received a Hello packet from a neighbor, containing the sending Router ID.

  • Down State
  • Init State
  • Two-Way State
  • ExStart State
  • Exchange State
  • Loading State
  • Full State

Explanation: In the Init State, Hello packets are received from neighbors, containing the sending Router ID.

4. During this OSPF state on point-to-point networks, the routers decide which router initiates the exchange of DBD packets.

  • Down State
  • Init State
  • Two-Way State
  • ExStart State
  • Exchange State
  • Loading State
  • Full State

Explanation: In the ExStart State on point-to-point networks, the routers decide which router initiates the exchange of DBD packets.

5. During this OSPF state, routers have converged link-state databases.

  • Down State
  • Init State
  • Two-Way State
  • ExStart State
  • Exchange State
  • Loading State
  • Full State

Explanation: In the Full State, routers have converged.

6. During this OSPF state, no Hello packets are received.

  • Down State
  • Init State
  • Two-Way State
  • ExStart State
  • Exchange State
  • Loading State
  • Full State

Explanation: In the Down State, no Hello packets are received.

7. During this OSPF state, routes are processed using the SPF algorithm.

  • Down State
  • Init State
  • Two-Way State
  • ExStart State
  • Exchange State
  • Loading State
  • Full State

Explanation: In the Loading State, routes are processed using the SPF algorithm.
