HI Friends

I need a kind help. I have a router at HQ 7500 Series. I was connecting to one of our branch router on a Serial interface before. Now we have changed the link and using dedicated DSL link to connect to the branch. The link is terminated on a ZHONE Modem then connect to the PA2-FE-TX port on the Router. on the moem the link is showing up but from the Router i am not able to reach the branch router.

At HQ Router

interface fa 1/1/0

ip addres

speed auto

duplex auto

At Branch

interface fa 0/1

ip add

speed auto

duplex auto

running EIGRP protocol between HQ and Branches.

STC (Telco) is saying the link is activatred and up. I am in trouble now, i need your immedaite help please.

Can we use PA2-FE-TX for this purpose.

Thanks and regards

invite telco to prove you that the circut is working, using two laptops connected to the DSL mpdems. After it works this way, it will work for routers.

Hello Jacob,

verify with your provider what kind of DSL links they are giving you.

You might have taken two DSL links and you need to make an IPSec VPN over the internet.

Or have you two SDSL modems in back to back ?

Your current configuration would be fine only for the last scenario.

Have you a DSL based ethernet extender ?



if so try

int f1/1/0

speed 10

duplex full

int f0/1

speed 10

duplex full

Hope to help

HI Giusee,

Thanks for the valuable information. At HQ the modem is ZHONE. I think the Telco technician was little confused and used a normal Modem (netwconnect modem) at the other end. I will check with the ISP and update.

thanks a lot again..
