Basic network lab but cannot ping from Remote router to London router and to laptop

[tony_bilton]

Hi,

Set up basic network.

2 routers: London and Remote

I'm connecting routers via a crossover cable:

London has a config:

interface Ethernet0/0

end

Can anyone tell me why I can ping from the laptop connected to Router London via a crossover to Remote e0/0 but cannot ping from Remote e0/0 to London e0/1 or the laptop which is on IP 192.168.128.2.

I can telnet from laptop to both routers and from either router to the other.

Thanks

At a guess, might this be in relation to IGRP performing automatic summarization of the networks?

Try adding a "no auto-summary" once you've entered "router igrp 10".

I only see one IP addresses, 192.168.64.2/26, on both London and Remote. I see no other configuration. Is something missing?

I noticed that, but just assumed that the wrong config had been copied/pasted into the message, since the description for E0/0 on the London router is "Link to London"..looks more likely that the config for remote was pasted twice instead.

Also, the ping from "remote" to 192.168.64.1 which is successful, is (I'm assuming) the E0/0 interface on London.

Hence my guess that if there are other networks off the London router (192.168.128.0, and 192.168.192.0, although no evidence of those since the config of the London router is missing), I was assuming that a likely candidate for the issue would be auto summarization of the 192.168.x.x networks..

Of course, since I'm still learning...I could easily be barking up the wrong tree.

Regards.

I agree....must have pasted in the wrong configs.
Nothing in there shows me that those two routers would work.
We need the actual configs to troubleshoot this.
Cheers!
