Question

If you accidentally configure one OSPF router with a network type as broadcast and the other router with a network type point-to-point:

a. Both routers will exchange their LSDB.
b. Both routers will reach full state.
c. Neither router will add IP routes to the routing tables.
d. Both a and b.

Answer 1

If you accidentally configure one OSPF router with a network type as broadcast and the other router with a network type point-to-point, both routers will exchange their Link State Database (LSDB) and reach full state, but they will not add IP routes to the routing tables.

Step-by-step explanation:

If you accidentally configure one OSPF router with a network type as broadcast and the other router with a network type point-to-point:

1. Both routers will exchange their LSDB. OSPF routers exchange Link State Advertisements (LSAs) to build and maintain the Link State Database (LSDB). By configuring one router as broadcast and the other as point-to-point, they will still exchange LSAs and update their LSDBs.
2. Both routers will reach full state. OSPF routers go through several states, including the full state, where they are fully adjacent and have exchanged all their LSAs. The incorrect network type configuration will not prevent the routers from reaching the full state.
3. Neither router will add IP routes to the routing tables. OSPF routers use the LSDB to calculate the shortest path to a destination and populate their routing tables with IP routes. However, the incorrect network type configuration may result in inconsistent or incomplete routing information.
