Which of the following packets are OSPF packets?
Which of the following packets are OSPF packets?
OSPF, which stands for Open Shortest Path First, is a routing protocol that uses several types of packets to establish and maintain router information. The primary OSPF packet types include HELLO, which is used to identify and maintain neighbor relationships; LSR (Link-State Request), which is used to request additional information about link-state advertisements (LSAs); and LSU (Link-State Update), which is used to provide updated link-state information. Although LSA (Link-State Advertisement) is an important concept in OSPF, it is not classified as an OSPF packet itself, but rather, it is the data conveyed within other OSPF packets like LSU.
A,B,C,D
The answer is ABCD
All the above
A B and C are correct answers. HELLO: Used to discover and maintain neighbor relationships. HELLO packets are sent periodically to each interface enabled for OSPF3. Link-State Request (LSR): Used to request more information about LSAs that are not known or are more recent. LSR packets are sent after receiving DBD packets3. Link-State Update (LSU): Used to send requested LSAs or to flood new or updated LSAs. LSU packets contain one or more LSAs and are acknowledged by Link-State Acknowledgment packets3
A,B,C. D is not a packet, LSA is routing information or LSA headers are in DD and LSAck packets.
All are correct. List of OSPF packets: Hello Database Description (DD) Link-State Advertisement (LSA) Link-State Request (LSR) Link-State Update (LSU) Link-State Acknowledgment (LSAck) Intra-Area Router Summary (IASR) Autonomous System External (ASE) Not-So-Stubby Area (NSSA) LSA Intra-Area Router Summary LSA for Internal Routing Redistribution External LSA
