Configure Cisco ASR901 with ATT ADI Fiber

etjen · ‎10-30-2019

Hi everyone -

We recently subscribed to ATT ADI fiber (500M) without the managed router from ATT so we can save the monthly cost in the long run. I recently bought Cisco ASR 901 and hope that I can configure the router on my own.

I am looking for some samples of configuration if someone here has done it before. I have been provided some technical information such as WAN information (CR Serial IP Address, IPv6 CR serial IP Address, Compresses IPv6 Serial IP Address, etc...) and LAN Information (LAN IP Gateway, IPv6 LAN IP Gateway, First Network Assignable, Usable IP Range, etc...).

I only have some basic skills on Cisco router. Any input will be greatly appreciated.

Hello,

best to post the current running configuration (sh run) of your ASR. Indicate which interfaces are connected to what (you can put a description on an interface with the 'description' interface command), and we can fill in the rest...

Here is the information from provider:

CR Serial IP Address:32.140.21.114/30
AR Serial IP Address:32.140.24.113/30
WAN IP Address: 32.140.24.112/30
LAN IP Gateway: 12.25.241.193
First Network Assignable:12.25.241.194
Usable IP Range:12.25.241.194 - 12.25.241.222
Broadcast IP Address:12.25.241.223
Subnet Mask:255.255.255.224

Also, when I tried to put ip address on the interface, I got an error stating "IP Address config under this interface is not supported on ASR901"

Here is the running config:

Router#show runn
