Re: Back-to-back configuration

Thanks a lot, its working.I can ping the other router let say 192.168.1.135 and the other router is 192.168.1.136 by using back-to-back connection via ppp.Now, I am trying to ping the fastethernet in the other router let say 1.0.0.1 and the other router is 1.0.0.2 but i failed to do so. It is possible to use ospf in this scenario or what configuration to add?

Re: Back-to-back configuration

You can certainly use OSPF in this configuration. You coulsalso just use static route since it is a rather straightforward scenario.

Re: Back-to-back configuration

Hi Harold,

Can you give a sample configuration for this,I am not very familiar with the OSPF. How can I configure a static route, the main thing for me is to ping both sides because my plan is to install the server 2000 on the other side and one server on the other side.Once again sorry for my mistake I hope you will continuing your support to guy like me.

Thanks a lot,

Re: Back-to-back configuration

There it is:

router ospf 1

netw 192.168.1.0 0.0.0.255 area 0 <---- serial link

netw 192.168.x.0 0.0.0.255 area 0 <---- Ethernet interface

x correspond to the subnet value you configure on router A and B.

This should be sufficient to ping from one router Ethernet to the other. Don't forget to configure the default gateway on the workstations/servers that you add on these subnets if you want to provide connectivity from one subnet to the other.

Hope this helps,

Re: Back-to-back configuration

Hi Harold,

Thanks a lot, my first network lab is working properly I can ping both sides by any way, via serial port or via ethernet. I can ping my win2k server but when I tried to join the other server in another subnet, I got an error message saying DNS cannot contacted. Since you are expert in Cisco routers is there any commands to add in the router or any configuration. I know its too much, all my questioned are solved because of your expertise thats why I am taking this opportunity to thank you.

Regards,

Jhun
