Name: Devangi Umretiya Student ID: 301305606 Section: 004 Lab: 004 You have been asked to troubleshoot the network configuration at Z-corp. In order to minimize disruption of the company network you have decided to copy the device configurations and recreate the network in a sandbox environment. Unfortunately, your sandbox equipment does not match the network equipment exactly forcing you to make some small configuration changes before pasting in the configuration files. • Please check the Gi interface slot numbers on the switches and make any necessary adjustments to the configuration files before pasting them into the devices. • The router configuration files supplied are designed to work on the 1841 first generation ISR. Your sanbox environment contains both 1841 and 1941 series routers. If you are using the second generation ISR (1941) you will have to change the reference from Fa to Gi for all Ethernet interfaces. Lab: • Cable the following network as illustrated. • Once cabled, load the initial configurations provided. Remember to add a no shutdown to any interfaces you wish to activate. • Test connectivity from SW1 to the ISP loopback interface (100.100.100.100). Troubleshoot as required. • Verify that all requirements specified above are met.

Setp NAT in Border to translate all internal IPs to 192.168.1.129/25 ( capture show ip NAT traslation) 5. Configure a default static route in Border and propagate it internally to R1 and R2

Name: Devangi Umretiya Student ID: 301305606 Section: 004 Lab: 004 Troubleshooting Steps 1. No VLANs are created on SW1 and SW2 To identify the problem : show interfaces vlan brief To solve the problem: (config)#vlan 10 (config-vlan) # name VLAN10 (config)#vlan 20 (config-vlan) #name VLAN20 (config)#vlan 30 (config-vlan )#name VLAN30 (config)#vlan 99 (config-vlan) #name VLAN99 2. Native VLANs are not same in both the switch. SW1 have VLAN 99 as a Native VLAN. Whereas, SW2 have VLAN1 (Default VLAN) as a Native VLAN. To identify the problem: show interfaces trunk To solve the problem: (config)#int range g0/1-2 (config-if) #switchport mode trunk (config-if) #switchport trunk native vlan 99 3. The IP of g0/0/0 on R1 was in a different subnet. To identify the problem: show ip interfaces brief To solve the problem: (config)#interface GigabitEthernet0/0/0 (config-if) #no ip address 10.10.10.2 255.255.255.252 (config-if) #ip address 10.10.10.6 255.255.255.252 (config-if) #no shut
