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
