　　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 - 192.168.77.34

　　Fa 1/0 - 192.168.60.81

　　Fa 0/1 - 192.168.60.65

　　RTR_2(config-router)#network 192.168.60.0

　　RTR_2(config-router)#network 192.168.77.0

　　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 192.168.77.0 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 192.168.77.0 is used between RTR_1 Fa0/0 - RTR_2 Fa 0/0 . Advertise this network into EIGRP

　　RTR_1(config-router)#network 192.168.77.0

　　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 198.0.18.6

　　RTR_2#ping 198.0.18.6

　　!!!!!

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

　　Any Questions are welcomed!!!!!
