OSPF Multiaccess Networks Quiz

DROTHERs use the multiaccess address 224.0.0.______ to send OSPF packets to the DR and BDR.

In the multiaccess topology, there are three routers interconnected over a common Ethernet multiaccess network, ______.

OSPF has automatically elected a ______ and BDR in multiaccess networks.

R3 has been elected as the DR because its router ID is ______.

R2 is the BDR because it has the second highest router ID, which is ______.

To verify OSPF router roles, use the ______ command.

R1 is not the DR or BDR, but is a DROTHER with a default priority of ______.

R1 has two adjacencies: one with the ______ and one with the DR.

To verify the OSPFv2 adjacencies, use the show ip ospf ______ command.

The state of neighbors in multiaccess networks can be ______ such as FULL or DROTHER.

FULL/DROTHER indicates a DR or BDR router that is fully ______ with a non-DR or BDR router.

A router in the FULL/DR state is fully adjacent with the indicated ______ neighbor.

The normal state for an OSPF router is usually ______.

In a 2-WAY state, a non-DR or BDR router can exchange ______ packets with another non-DR or BDR router.

If a router is stuck in a state other than FULL, it is an indication that there are ______ in forming adjacencies.

The Backup Designated Router (BDR) can also be referred to by the ______ neighbor.

The ______ state is considered normal in a multiaccess broadcast network.

In OSPF, the Internet Address for a router can be expressed as ______/24.
