Explanation:

Step1:

Identify the faults in configuration on RTR_1 and RTR_2. As the SIM specifies all other inter connectivity and internet access for the existing locations of the company are working properly.

Routing Protocols used in the SIM is EIGRP with AS 212 as provided by exhibit.

Faults Identified:

Wrong AS (EIGRP 22) provided at RTR_2 (New router)

RTR_1 does not advertise the new network between RTR_1 and RTR_2 into EIGRP.

We need to correct the above two configuration mistakes to have full connectivity

Step2: Correcting the EIGRP AS to 212

Wrong AS (EIGRP 22) provided at RTR_2 (New router)

All routers that want to exchange routes within EIGRP needs to be in same Autonomous System.

Step 2.1:

First we need to remove the current wrong EIGRP AS 22 from Router RTR_2

Click on Host-F to get CLI of RTR_2

RTR_2>enable

Password : cisco (Provided by SIM Q )

RTR_2#conf t

RTR_2(conf)#

Step 2.2:

Removing the wrong EIGRP routing process with AS 22

RTR_2(conf)#no router eigrp 22

The above statement removes all the EIGRP configuration configured for AS 22 .

Step 2.3:

Adding the correct EIGRP configuration

Start the EIGRP routing process with AS 212

RTR_2(conf)#router eigrp 212

Step 2.4:

Advertise the directly connected networks into EIGRP on RTR_2

Fa 0/0 -

Fa 1/0 -

Fa 0/1 -

RTR_2(config-router)#network

RTR_2(config-router)#network

RTR_2(config-router)#no auto-summary

RTR_2(config-router)#end

Step 2.5:

Important save the changes made to router RTR_2

RTR_2#copy run start

Step 3:

RTR_1 does not advertise the new network between RTR_1 and RTR_2 into EIGRP.

Click on Host-G to get CLI of RTR_1

The network is used between RTR_1 Fa0/0 - RTR_2 Fa 0/0

This network needs to be advertise into EIGRP routing process at RTR_1

RTR_1>enable

Password : cisco (Provided by SIM Q )

RTR_1#conf t

RTR_1(conf)#

Step 3.1:

Enter EIGRP routing process for AS 212

RTR_1(conf)#router eigrp 212

Step 3.2:

The network is used between RTR_1 Fa0/0 - RTR_2 Fa 0/0 . Advertise this network into EIGRP

RTR_1(config-router)#network

RTR_1(config-router)#end

Step 3.3:

Important save the changes made to router RTR_1

RTR_1#copy run start

Verification:

From RTR_2 CLI

ping RTR_1 Serial 1/0 IP address

RTR_2#ping

!!!!!

A successful ping shows the new RTR_2 will have full connectivity with other routers.

Any Questions are welcomed!!!!!
