EIGRP (New):

After adding RTR_2 router, no routing updates are being exchanged between RTR_1 and the new location. All other inter connectivity and internet access for the existing locations of the company are working properly.

The task is to identify the fault(s) and correct the router configuration to provide full connectivity between the routers.
Access to the router CLI can be gained by clicking on the appropriate host.
All passwords on all routers are cisco.

IP addresses are listed in the chart below.


Solution to the Simulation:
Check the running configuration of all the routers and routing protocol information and note the anomalies where sighted/found ......

Explanation, Fault Identification and Correction
Step1: Simulation understanding
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:
  1. Wrong AS (EIGRP 22) provided at RTR_2 (New router),
  2. 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
Correction:
Step2:
Correcting the EIGRP AS to 212 & Advertise the routes
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.
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 in the simulation)
RTR_2#conf t
RTR_2(conf)#
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
Adding the correct EIGRP configuration. Start the EIGRP routing process with AS 212
RTR_2(conf)#router eigrp 212
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
Note: Necessary step, 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 in simulation)
RTR_1#conf t
RTR_1(conf)#
Enter EIGRP routing process for AS 212
RTR_1(conf)#router eigrp 212
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
Important save the changes made to router
RTR_1RTR_1#copy run start
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.
