CCNA ICND1 Lab9 - Layer 3 Switch and Proxy Server

An enterprise LAN often uses private IP addresses. A private IP address must be translated to a public IP address before connecting to the Internet. When a layer 3 switch replaces a router, because the layer 3 switch does not have the NAT function, a proxy server is required.

Lab Requirements:

1. Complete the configuration as the figure requires.

2. Segment the VLAN into two VLANs. Enable layer 3 routing. Specify a gateway for every VLAN.

Note:

1. The CCNA lab does not require proxy server configuration.

2. PC configuration is omitted.

Lab Process:

P4S-R#configure terminal                      / Enter the VLAN database

P4S-R(vlan)#vlan 1

P4S-R(vlan)#name router1                        / Name vlan1 router1

P4S-R(vlan)#vlan 2

P4S-R(vlan)#name router2                  / Name vlan2 router2

P4S-R(vlan)#exit

P4S-R(config)#ip routing                        / Enable the IP routing of the switch
