Home Router Setup

Home Router Setup - Part 2: Interfaces & Services

In this post I'll be setting up my network interfaces and some network services, DNS and DHCP.

Below is a diagram of the lab I'll be using.




Part 2 - Interfaces and Services


Here I will set up the 2 network interfaces and remove CDP from the Test Network interface.

Router1(config)#interface ethernet 0
Router1(config-if)#ip address 10.0.2.254 255.255.255.0
Router1(config-if)#no cdp enable
Router1(config-if)#exit

Router1(config)#interface ethernet 1
Router1(config-if)#ip address 10.0.1.254 255.255.255.0
Router1(config-if)#no shut
Router1(config-if)#exit



I configure the router to use the Extreme router as it's default gateway. I will also configure it to use OpenDNS name servers and to resolve DNS queries for other network hosts.

Router1(config)#ip route 0.0.0.0 0.0.0.0 10.0.1.1
Router1(config)#ip domain-lookup
Router1(config)#ip name-server 208.67.222.222
Router1(config)#ip name-server 208.67.220.220
Router1(config)#ip dns server
Router1(config)#exit



Next I configure DHCP for the Test Network.

Router1(config)#service dhcp
Router1(config)#ip dhcp pool TEST_NETWORK_DHCP_POOL
Router1(dhcp-config)#network 10.0.2.0 /24
Router1(dhcp-config)#domain-name walliford.local
Router1(dhcp-config)#dns-server 10.0.2.254
Router1(dhcp-config)#default-router 10.0.2.254
Router1(dhcp-config)#lease 7
Router1(dhcp-config)#exit



I include exclusions so only 10.0.2.10 - 10.0.2.20 are used for DHCP clients.

Router1(config)#ip dhcp excluded-address 10.0.2.1 10.0.2.9
Router1(config)#ip dhcp excluded-address 10.0.2.21 10.0.2.255
Router1(config)#end
