Check weather the below statements are Right or Wrong

 

1After executing the "show ip eigrp neighbor" command on router A, the value in the column identified by the acronym "Q cnt" has a value equal to 3. This means that there is congestion on the network.

 

2-You have activated the EIGRP "debug" process, to see the content in the log you must use the "show logging" command

3Router A has the following values K1 = 1, K2 = 0, K3 = 1, K4 = 0, K5 = 0, AS = 100, Router B has the following values K1 = 1, K2 = 0, K3 = 0, K4 = 0, K5 = 0, AS = 100. After router A sends a "hello" message to router B and knows the values, a neighbor relationship is created between A and B.

 

4-The variance is preferably used when we perform load balancing using lines that do not have the same cost

 

5-EIGRP allows routes to be updated by using partial updates when a change in the metric of a route occurs.

 

6-If router A has a different hold timer than router B, the EIGRP neighbor relationship cannot be carried out due to the time difference.

 

7-In EIGRP for a route to be categorized as a fallback successor "feasible successor", the number of the advertised distance "advertised distance" must be less than the number of the best route "successor".

 

8-An EIGRP router does not complete a neighbor relationship if the K values (EIGRP metric weight) are not equal when doing a "hello" message transaction.

 

9 EIGRP bandwidth consumption is similar to IGRP.

 

10 In an OSPF packet, the identification of the area in its binary structure is optional.

 

11-In OSPF, "Link State Advertisement" (LSA) messages are sent by "multicast" transmission using the address 224.0.0.5 to all OSPF routers.

 

12-In OSPF by default in router identifier selection, the highest IP address of the active physical interfaces is selected by OSPF as the router identifier.

 

13-The data contained in an OSPF packet is information that is included in layer 2 of the OSI model.

 

14-In IS-IS the use of several hierarchical levels does not necessarily represent a way to limit the flooding of messages that announce the state of the link.

 

15-In OSPF only one router calculates the best routes using the SPF algorithm.

 

16-In OSPF, a router will always be responsible for forwarding any new LSA message it receives to the other neighbors to achieve complete synchronization of the links in the area.

17-One of the advantages of having a DR and a BDR when using OSPF is to reduce traffic during updates.

18-The link identifier "link-state ID" of the "Link State Advertisement" (LSA) type 2 is the "loopback" address of the designated router (DR).Bottom of Form

19-A designated router (DR) in OSPF receives multicast messages through the address 224.0.0.6.

20-A router in OSPF can declare that another router is its neighbor after exchanging hello messages.

21-There is no way to confirm the origin of a "Link State Advertisement" (LSA) message.

22-In OSPF "Totally Stub Area" operation, the area border router (ABR) will be responsible for blocking type 5 messages from external "Link State Advertisements" (LSA).

23-In OSPF by "default" the cost of an interface is determined by its bandwidth.

 

24-In OSPF the topology database is created in part thanks to the information that comes from the "Link State Advertisements" (LSA).
