Newbie, need help setting up routers in test lab

[l9nux]

Hi,

I'm a complete newbie to Cisco so I'd really apreciate any help here...

I need help in setting up my practice lab which consists of 2 x Cisco 2610 routers each with an ethernet and a serial interface. I've got a DB60 DCE/DTE cable, and I want to emulate a leased line.

Are there any good guides out there, or could anyone point me in the right direction? This is what I've done so far:

router1 (eth0/0 192.168.4.100/24) - This has a serial interface with a DTE / DCE DB60 cable to router2. The DTE end is in this router.

router2 (eth0/0 192.168.5.100/24) - This has a serial connection with the DCE end.

I've set up my hostnames, and passwords, given each routers ethernet interface an IP address (see above), but I have no idea where to start to get the two routers talking?

I read about setting the clock rate on the router with the DCE end, which I've done. As expected, I can't ping the other router, so I guess I need to setup routing? Should this be static or using RIP? Am I completely off course here?

The configuration of all my interfaces are as follows:

Any help would be really apreciated, as everything I've read so far hasn't helped get this working.

Thanks,

I think the reason you're not connected is because the interfaces are on different subnets. If the Ethernet0/0 interface of Router1 is on the 192.168.4.0/24 subnet so should the Ethernet0/0 interface of Router2. An example would be to give e0/0 of router1 an ip address of 192.168.4.1 and e0/0 of router2 an ip address of 192.168.4.2. Same thing with the serial interfaces.

Ah ha! I've done it!!

I've changed the configuration slightly, but I've had to add the appropriate routes!

jguerra81, I have to have different IP's on each routers ethernet0/0 interface because that's the IP subnet of each network.

I didn't realise that the ip addresses for the serial interfaces DO have to be on the same network. Makes sense really! Once I set that, and then added the routes to each network it worked great!

The only thing that I can't do now is telnet to Network B from a computer in Network A. The comptuer in Network A can ping the router in Network B with no problem, but it won't telnet?

My configuration is now as follows:

Sorted the telnet problem! I couldn't telnet into the router on the other network because my ISA server firewall client was running!
