Objective: configure Routers 1 and 2 with IP addresses, and ping between them to test connectivity. Then view the entries stored in the Address Resolution Protocol (ARP) table. Lab Equipment: Router 1 and Router 2 from the eRouters menu Background Reading: Lab Primer Lesson 6: ARP 1. Connect to Router 1, and type the command to view the ARP table. Router>enable

Router#show arp

2. Assign an IP address of 10.1.1.1 255.255.255.0 to the Ethernet 0 interface of Router 1. Router#conf terminal

Router(config)#interface Ethernet 0

Router(config-if)#ip address 10.1.1.1 255.255.255.0

Router(config-if)# no shutdown

Router(config-if)#exit

3. View the ARP table again. Router(config)#exit

Router#show arp

4. Now, connect to Router 2, and configure its Ethernet 0 interface with an IP address of 10.1.1.2 /24. Router#conf terminal

Router(config)#interface Ethernet 0

Router(config-if)#ip address 10.1.1.2 255.255.255.0

Router(config-if)# no shutdown

Router(config-if)#exit

5. A connection should now exist between the Router 1 and Router 2 Ethernet interfaces. To ensure that the connection is functional, ping the IP address of Router 1’s Ethernet 0 IP address from Router 2. Router(config)#exit

Router#ping 10.1.1.1

6. View the ARP table on Router 2, and notice the entry. Router#show arp

7. Now, clear the ARP table. Router#clear arp

8. View the ARP table one last time, and notice what entries are there. Router#show arp
