1721's with WIC-1ENET routing between...cant ping between interfaces!! 2

[flyboy1701]

Hi everyone, I would really appreciate some help here, on something which I am sure is very basic, but nevertheless I am banging my head against a brick wall.

I have 2 x 1721's both runnning IOS 12.3(1a) with WIC-1ENET modules in slot 0, I am trying to route between the two interfaces, but cannot get each router to ping the others ethernet interface. As a test though I have given my laptop the IP address of the other ethernet interface and connected directly to the router...essentially simulating the other router, and I can ping between them, but when I plug the routers back-to-back....nothing again.

I have attached the 2 configs, and would really appreciate any help.

Thanks

You need a crossover cable between the two routers, not a straight through.

Burt

 

[flyboy1701]

Yeah, I have a cross-over between them, the interfaces are up and LINK light active

No need to confuse the routers---the interfaces (and thus the two networks) are directly connected. Post an extended ping result from Wheatsheaf_Pub to Function_Room, choosing int e0.

Removed the route and still no joy, here is the ping results

Still no joy though, I have checked all off the basics, i.e. IOS version, processor etc and all match, but this just will now work when the routers are back to back, yet when i place a laptop with a static address of the reciprocal address, it works......I am puzzled

 

[burtsbees]

You're not using the same cable as the laptop, are you?

Burt

 

[flyboy1701]

No, I know the difference between a straight through and a cross-over like I said the interface and line protocol for both routers are up

 

[flyboy1701]

Could this explain why I am not able to get this to work

[burtsbees]

No. Post a sh run from both routers...

Do this on both routers! If this does not work, I would say it is a cable problem. If you can attach a laptop on one fastethernet port and ping the other router's e0, and do this with both routers, I would definitely say that it is a cable problem. Post a sh cdp nei det, sh ip int bri, and sh ip route from both routers.
Sorry---forgot you had already posted the configs!

Burt

 

[flyboy1701]

Hi Burt, I am 100% confident the cable is ok, I have already tested this, and the wic-1enet only operates at 10 mpbs so there is no speed command applicable to it

 

[burtsbees]

Crap---that's right...
Please post what I have asked you for, and let me know what can ping what (laptop to what interface? Both routers, etc.).

Burt

heres the info you requested Burt....and thanks for your help


PC A- 192.168.2.10
Router (Function _room) F/E0 192.168.2.3 & E0 192.168.100.2

PC B- 192.168.1.10
Router (Wheatsheaf_Pub) F/E0 192.168.1.1 & E0 192.168.100.1

PC A can ping router function room (F/E0) and vice versa

PC B can ping router Wheatsheaf_pub (F/E0) and vice versa

PC A cannot ping PC B

Router fucntion room E0 cannot ping wheatsheaf_Pub E0 when back to backed with a cross-over cable, though when a laptop is connected to e0 and given other routers address, this works.

 

[burtsbees]

So a laptop was connected to e0 of BOTH routers, and in BOTH cases it was able to ping the IP address of E0???
One more thing---post sh int e0 from both routers---let's look and input/output errors/giants, etc...

Burt

 

[flyboy1701]

Yep thats correct and the router coudl ping the laptop, it appears to an interoperability issue between the e0 interfaces
