Help with Cisco 1720 DS1 config
Posted on 2004-10-13
I'm a Cisco wannabe expert and I just had a DS1 (T1) turned on in my office. I have a Cisco 1720 Router and although I was hoping that my ISP would have sent me the config in Cisco router language, they sent me what's below. Can someone help me with providing what my Cisco config should look like when I do a "show config"?
*Note - I've x'd my ip's to keep them private.
LAN Range Info:
Useable IP addresses: xx.xx.xx.xx - xx.xx.xx.xx
Subnet Mask: 255.255.255.240
Gateway Address: xx.xx.xx.xx
For DNS Resolution -
Primary DNS Server: xx.xx.xx.xx
Secondary DNS Server: xx.xx.xx.xx
Below are recommended configuration settings for your equipment should you choose not to take advantage of
Broadwing Communications' turnkey solution.
Please provide these settings to your equipment vendor/configurator to ensure a smooth service installation.
CPE* LAN address/mask: xx.xx.xx.xx / 255.255.255.240
CPE* WAN address/mask: xx.xx.xx.xx / 255.255.255.252
Broadwing WAN address/mask: xx.xx.xx.xx / 255.255.255.252
A default route should be setup in the router as follows:
network / mask: 0.0.0.0 / 0.0.0.0
* CPE refers to the Customer Premise Equipment.
LAN refers to the port used to connect to the internal network.
WAN refers to the port used to connect to the dedicated circuit.
