Question 1

broadcast network type

Answer 1

broadcast network type
An OSPF interface setting, useful on links with more than two routers, resulting in an LSA flooding process managed by an elected designated router (DR).

Question 2

interface bandwidth

Answer 2

In OSPF, the numerator in the calculation of an interface’s default OSPF cost metric, calculated as the interface bandwidth divided by the reference bandwidth.

Question 3

OSPF priority

Answer 3

OSPF priority
An OSPF interface setting that serves as the first comparison point in the designated router (DR) election process, with the router interface with the highest priority winning the election.

Question 4

passive interface

Answer 4

With a routing protocol, a router interface for which the routing protocol is enabled on the interface, but for which the routing protocol does not send routing protocol messages out that interface.

Question 5

point-to-point network type

Answer 5

point-to-point network type
An OSPF interface setting, useful on links in a point-to-point topology with only two routers, resulting in flooding directly between the routers without the use of a designated router (DR).

Question 6

reference bandwidth

Answer 6

reference bandwidth
In OSPF, a configurable value for the OSPF routing process, used by OSPF when calculating an interface’s default OSPF cost metric, calculated as the interface’s bandwidth divided by the reference bandwidth.
