| Question ID 13600 | What information does a router running a link-state protocol use to build and maintain its
topological database? (Choose two.)
|
| Option A | hello packets
|
| Option B | SAP messages sent by other routers
|
| Option C | LSAs from other routers
|
| Option D | beacons received on point-to-point links
|
| Option E | routing tables received from other link-state routers
|
| Option F | TTL packets from designated routers
|
| Correct Answer | A,C |
Explanation Explanation: Neighbor discovery is the first step in getting a link state environment up and running. In keeping with the friendly neighbor terminology, a Hello protocol is used for this step. The protocol will define a Hello packet format and a procedure for exchanging the packets and processing the information the packets contain. After the adjacencies are established, the routers may begin sending out LSAs. As the term flooding implies, the advertisements are sent to every neighbor. In turn, each received LSA is copied and forwarded to every neighbor except the one that sent the LSA.
