Question
v.o(15pts) Build the routing table for Router A n the following table. Router C is a border gateway router which gets the advertisement of 144.122.212.0/22 from another A.S. The AS of Router A uses OSPF for intra-AS routing. i sement. 144.122.212.0/22 Int Int AD Int AB E 144.122.216.0121 122. a) Complete the Logical Routing Table of Router A using the necessary algorithm in the table below. Indicate the routing protocol (s) that is used to construct each entry. Algorithm (Use as many rows as you need): Current set De D), p(D) Logical Routing Table: Interface (AB, AC or AD) Subnet 144.122.208.0/20 44.122.208.0/21 144.122.216.0/21 144.122.212.0/22 Rout tocols (OSPF, BGP)Explanation / Answer
ANSWER:
. The steering table may incorporate particular system passages or essentially a solitary default course. The data in the steering table is utilized by the sending procedure to forward activity to the goal system or host. The steering table itself does not in reality forward activity.
In the event that the course passage does not as of now exist in the steering table, add it to the directing tableOn the off chance that the course section is more particular than a current course, add it to the steering table. It ought to likewise be noticed that the less particular section is still additionally held in the steering tableIn the event that the course passage is the same as a current one, however is gotten from a more favored course source, supplant the old section with the new passage
On the off chance that the course passage is the same as a current one, and is gotten from a similar convention:Dispose of the new course if the metric is higher than the current courseSupplant the current course if the metric of the new course is lower
When courses have been set into the directing table, as a matter of course the most particular or longest match prefix will dependably be favored over less particular courses. This is shown in the accompanying illustration which demonstrates a steering table that contains passages for the 80.0.0.0/8, 80.1.0.0/16, and the 80.1.1.0/24 prefixes. These three course prefixes are gotten by means of the EIGRP, OSPF, and RIP directing conventions, individually.

Codes: C – associated, S – static, R – RIP, M – portable, B – BGP
D – EIGRP, EX – EIGRP outside, O – OSPF, IA – OSPF bury territory
N1 – OSPF NSSA outside sort 1, N2 – OSPF NSSA outer compose 2
E1 – OSPF outer compose 1, E2 – OSPF outside sort 2
I – IS-IS, L1 – IS-IS level-1, L2 – IS-IS level-2, ia – IS-IS entomb zone
* – hopeful default, U – per-client static course, o – ODR
P – intermittent downloaded static routeGateway of final resort isn't set
R 80.1.1.0/24 [120/1] by means of 10.1.1.2, 00:00:04, Ethernet0/0.1
D 80.0.0.0/8 [90/281600] by means of 10.1.1.2, 00:02:02, Ethernet0/0.1
O E2 80.1.0.0/16 [110/20] by means of 10.1.1.2, 00:00:14, Ethernet0/0.1
. The second course is the 80.0.0.0/8 course. This course is found out by means of inward EIGRP and along these lines has a default managerial separation estimation of 90. The third course is the 80.1.0.0/16 course. This course is found out by means of OSPF and is an outside OSPF course that has an authoritative separation of 110.
