Providing internet access

[RadioX]

I have a customer with a Cisco 1720 that we are going to provide with T1 access from our lines. He has a T1CSU/DSU as do I that are connected. How do I have to set up the router IOS to do this function. I have the CSU's configured with IP's and the approprice linecodes and framing and speed. But I need to know how to route him traffic in and out so he has an internet connection. Hopefully this makes sense. I am new to providing service to other people but familiar with all other forms of routing. Just need a little push in the right direction I guess.

Thanks in advance for all your help and comments

Normally you would set the router up with a point to point
T1 or a frame relay connection.

Lets say that the connection is a PPP you will need the following information.

1= what the bandwidth of the circuit 256,512,1536 etc etc
2=what is the ip address from the ISP and what is the gateway back to the ISP. Normally the serial IP would be something like 208.13.125.12 and the gateway 208.13.125.11 as you see the gateway is one less

3= The statement would look like this
ip route 0.0.0.0 0.0.0.0 208.13.125.11

4= if there is a range of ip's do not forget to input the
correct subnet mask. 252, 240,248 whatever is needed.

I have some configs at work if you need one let me know and i will post it. Good Luck !!!! Jeter@LasVegas.com

Yes those configs would be great. We are the ISP for this setup. This is very new to us and the customer we are hooking up knows they are are test dummy. Here is my current router config for them.

My serial interface
Serial1/0:0
ip 206.28.30.5 255.255.255.252
encapsulation PPP

there serial interface
Serial0
ip 206.28.30.6 255.255.255.252
encapsulation PPP

I have no op routes setup for either one

Thanks for your help

Oops. Looks like a typo for the serial port address in the PPP section. Should be .6 instead of .5

Jeter, can you tell me the benefits of having both a default-gateway and a static route to 0.0.0.0?

 

[jeter]

The config was off an existing router I just copied it.
With the Static route we/I normally would not use a default-gateway. Your right a type O on the .5 and .6 Jeter@LasVegas.com
