[Config] 1700 to 1700 routing - HELP in Cisco http://www.dslreports.com/forum/r8812353 en Sun, 29 Nov 2009 08:54:21 EDT Sun, 29 Nov 2009 08:54:21 EDT Re: [Config] 1700 to 1700 routing - HELP http://www.dslreports.com/forum/remark,8817520 dpocoroba : Acording to your diagram the ehternet segments MUST be on the same subnet. Your serial interfaces need to be on different subnets, hope that clears things up :)

I haven't gotten over to the routers yet, but something just hit me on the head with a loud bang.

I just realized (and feel free to correct me if I'm wrong) that I cannot have 2 routers on the same class C. My problem before was I was trying to set the IP addresses of both routers to 10.100.1.x/24 and 10.100.1.n/24...not realizing that doing that is going to make the routers gripe. Instead, I have to set one router to 10.100.1.x and the other to 10.100.2.x

Am I on the right track here?]]> http://www.dslreports.com/forum/remark,8813333 Wed, 17 Dec 2003 12:27:26 EDT Re: [Config] 1700 to 1700 routing - HELP http://www.dslreports.com/forum/remark,8812774 dpocoroba :

Are both the t1 and ethernet connections between the two routers necessary? He didn't say specifically that either one should be used. I just didn't know if both were required.


No both are not required. Its just easier to set up the ethernet segments. Since all you have to worry about is them being on the same subnet and not shut down :) The other thing you may have to worry about depending on physicly your Pc's will be connected to the serials. Is the encapsulation of those interfaces by default its HDLC, This may require some tweaking to maybe PPP.

First off seems rather strange that he would have you connect to the PC's with the serial cable and not ethernet :). Did he give you requirements you have to follow? Like ex: have to use the T1 and/or ethernet segment? Easiest way would be to use just the ethernet segment. and set up rip or ospf to be your routing protocol.

This might be a good starting point for you
Thanks for the quick reply, dpocoroba See Profile. I don't know why the PCs are connected with serial and not ethernet either. I guess it's because we work a lot with adtrans (which connect via serial) and he did it out of habit. ;)

But thanks, I will try that out...it's a lot more than my two days of constant bursting of blood vessels in my head produced. Thanks. ]]> http://www.dslreports.com/forum/remark,8812715 Wed, 17 Dec 2003 11:19:39 EDT Re: [Config] 1700 to 1700 routing - HELP http://www.dslreports.com/forum/remark,8812571 dpocoroba : First off seems rather strange that he would have you connect to the PC's with the serial cable and not ethernet :).

Haven't posted in this forum before, so it his is not appropriate, please let me know.

I have been given this lab exercise by my boss, and basically, all he said was "make these talk to eachother".

It's 2 Cisco 1700s, connected by both ethernet and t1 crossover. Each router is connected to a PC via serial cable. And both with blank configurations. (excuse my crude mockup)

Here's what I understand:
•Each interface needs an IP address
•They have to be on the same subnet
•I need to "ip route" statements on both sides or I won't be able to get a reply back

Here's what I don't understand:
•Subnetting (in its entirety)

Basically, all my experience with networking is in home networking...i.e. DSL/Cable modem to Linksys, out to PC(s). I haven't worked with subnets (and don't fully understand it) other than a basic 255.255.255.0 class C subnet.

Can anyone point me in the right direction and/or offer some helpful hints?
