The computation of the shortest path in OSPF is usually done by
Which of the following is false with respect to the features of OSPF
In OSPF, which protocol is used to discover neighbour routers automatically?
Which of the following is not a type of OSPF packet?
Correct order of the operations of OSPF
1. Hello packets
2. Propagation of link-state information and building of routing tables
3. Establishing adjacencies and synchronisation database
In OSPF header, which field is used to detect errors in the packet?
In OSPF database descriptor packet, if more database descriptor packet flows, ‘M’ field is set to
In OSPF database descriptor packet, which field is used to indicate that the router is master
In OSPF database descriptor packet, which field is used to detect a missing packet
An OSPF router receives an LSA, the router checks its sequence number, and thisnumber matches the sequence number of the LSA that the receiving router already has.What does the receiving router do with the LSA?
An OSPF router receives an LSA. The router checks its sequence number and finds thatthis number is higher than the sequence number it already has. Which two tasks doesthe router perform with the LSA?
An OSPF router receives an LSA. The router checks its sequence number and finds thatthis number is lower than the sequence number it already has. What does the router dowith the LSA?
Each LSA has its own age timer. By default, how long does an LSA wait before requiring an update?
Distance vector protocols use the concept of split horizon, but link-state routing protocols, such as OSPF, do not.
The outcome of Dijkstra’s calculation is used to populate the __________
Which multicast address does the OSPF Hello protocol use?
The Hello protocol sends periodic updates to ensure that a neighbor relationship is maintained between adjacent routers.
DBD packets are involved during which two states?
