The 20.20.20.14 address is the IP address that our ISP assigned the inside network as a whole. This is the internet (WAN) side IP address of router R2. 209.101.21.1 represents a HTTP server somewhere in the internet. The 'internet' in the topology is for representing the idea that the ISP leads to internet. We will not be connecting to the internet. For the purposes of this lab, we will consider the loopback address of the ISP router as a server on the internet Equipment: o 3 routers (Cisco 2811) o 1 switch (Cisco 2960) o 2 computers o Straight-through and cross-over UTP cables Complete the addressing table (no IP address to be selected for the switch): Device Router 1 Router 1 Subnet mask 255.255.255.0 Default gateway N/A Interface Fa0/0 Fa0/1 Fa0/0 IP Address 10.10.60.3/28 10.10.60.1/30 10.10.60.3/28 10.10.60.2/30 255.255.255.252 N/A Router 2 255.255.255.0 N/A Router 2 Fa0/1 255.255.255.252 N/A ISP Fa0/0 20.20.20.1 255.255.255.240 N/A ISP Loopbacko 209.101.21.1 255.255.255.255 N/A PC1 Ethernet 198.162.1.0 255.255.255.240 10.10.10.1 Summary of router interfaces: Record the results On Router R1: Display using the command show ip interface brief Names of the interfaces, exactly as shown Are the interfaces set up with IP addresses?

REPEAT the below set of commands for each interface on each router (R1, R2 and ISP) that is used in the topology using the appropriate IP addresses and subnet mask. {Note: This is a set of sample commands. You need to customize them according to the addressing table on page 2.)

In addition, The ISP router has a loopback address. The loopback is a virtual interface on the router that is always active. The address represents a remote web server that the PC could ping. You can configure the IP address on the loopbacko interface as follows (exact commands shown): ISP (config)# interface loopbacko ISP (config-if)# ip address 209.101.21.1 255.255.255.255 ISP (config-if)# no shutdown ISP (config-if)# end 3.
