PPP Chap Serial interface need routing if directly connected

[Confuseis]

Hi

I'm working on my 1st packet tracer project & looking to connect routers/Networks via PPP CHAP

I have the routers connected to each others serial interface using a DTE Cable

Have:

Set the Serial interface to PPP authentication Chap

set the user name and password for the opposite routers on both router's

set the clock speed

The links look to be up but I cannot ping from one network to the other. Looks the ping gets to the router and no further.

I thought as the 2 serial links are directly connected that this may be enough but perhaps I need to set up some routing also ?

I'm wondering what I'm missing, researching my config online shows I have covered everything but

alas cant ping across the link.

The show interface command show's ppp is set on bother routers serial interfaces.

Some of the commands Ive used are below

I've also attached the packet tracer file for clarity.   

Thanks for reading & Happy Easter

Router(config)#                 hostname   DubRouter

Router(config)#                 username   CorkRouter                    password cisco

Router(config)#                 int serial 0/3/0

DubRouter(config-if)#      encapsulation ppp

DubRouter(config-if)#      ppp authentication chap

DubRouter(config-if)#     clock rate 2000000

Hello,

both your routers need a default route:

Cork Router

ip route 0.0.0.0 0.0.0.0 200.0.0.1

Dub HQ Router

ip route 0.0.0.0 0.0.0.0 200.0.0.2

As a first step in investigating this issue would you post the output of show ip interface brief?

I agree that having a default route is a good thing for the config. But the immediate problem seems to be that the router can not ping the connected peer address. This would not have anything to do with whether there is a default route.

Actually, when I open your file, I can ping the other end of the serial link from each router, without modifying anything. After adding the default routes, there is end to end connectivity from LAN to LAN. Find attached the working file...

Looks good I'm gonna revise the default routes now

Thanks
