need a simple Point to Point config setup for 1760 routers 2

[gman10]

Good morning to all-

I need a rather simple config setup for two routers doing point to point. Both have been setup with Verizon T1 service and the routers are Cisco 1760 routers. Can someone point the way with perhaps a url or site with template configs out there? There will be no VPNing in or outside traffic going out just an end to end connection between two sites.. I have a general config started on both routers and from what I've heard from a few staff members at one of the two customer sites, there may eventually be a PIX firewall deployed behind one of the two sites and perhaps a pc ... eventually.. Anyone know of a good reference to view such a scenario, once again, I've started the configs just need slight guidance to solidify the this solution!

thx everyone

Hi Nawlej,

I just want to be sure if I would need to use the same AS number for EIGRP on the two routers.. thx again buddy!!!

gman

 

[lgarner]

Yes. Use the same AS number for all routers. Only routers with the same AS number will exchange routes with each other.

Using different AS numbers involves route redistribution and is normally found in much larger environments.

Again,

Thx so much to all for helping me so much with this solution!

Hi Dearingkr and everyone else,

I wanted to thank everyone again for all the solution entries made toward gettting this PtoP situation going.. It's working really well from both ends.. I wanted to know what I could do if there was "video" I needed to transfer from router B to router A.. I have EIGRP running on both routers but have no access lists setup.. essentially, the video is a Digital Video Recorder on a desktop Windows 2000 pc.. This pc has capable DVR software on it that captures video from cameras at site B (router B).. Is there a specific "video" port I would need to open to allow this traffic to enter router A, either thru a access-list w/ accomodating port #? I think the customer is deploying a PIX on Router A where all traffic will be coming in from Router B on this T1 PtoP assessment..

Here are my configs on routerA and routerB.. I will also research what video ports are needed to be open for "streaming video".. I'm not sure if I'll need a port open for it since this is a dedicated T1 and the video is stored on a Windows 2000 PC(DVR actually). anyway, here are the configs:

congratulations.

Glad I could help.

Usually the program you are using for the video will tell you which ports are utilized for communication. Check with the company of the application, and ask them that question.

If there are no access lists on your router, then I dont see how transmission would be disrupted to begin with. No ACL = Everything passes.

Also in the future - you should avoid sharing information such as SNMP communities, public IPs, and telnet passwords. When you past the config, just simply erase those parts out.

 

[gman10]

Thx Illegal, Dearingkr:

Will do, nothing should be as out in the open as I did it.. your right! I'll check the Video Corp user manual and assess what com port is needed.. thx again for all the this information

thx

Hello! I'm trying to do much the same as gman10 execpt
that I want the subnets on each of the FastEthernet
interfaces to be the same. So far, I've been unable
to get the routers to do this (I'm a real newbie at
this Cisco router stuff :-| ).

It should look like this:

"main network" "remote network"
192.168.10.x/24 192.168.10.x/24
| |
| |
switch switch
| |
| |
RouterA RouterB
E0 192.168.10.5/24 E0 192.168.10.6/24
S0 10.10.210.1/30 S0 10.10.210.2/30
| |
------------- T1 -----------------

Essentially, I want it to look like just another
ethernet cable.

All of my network resources are on the RouterA side
and I've got 50 workstations on RouterB side that
need to access those resources (DHCP, file servers,
internet access, etc.) on RouterA's side.

Here's the results of "show running-config" on RouterA0:

end

Any glaring errors?

Conceptually, the hard part for me is getting the router
to understand that _all_ packets go to the other side -
even if they're from the same sub-net.

Any help you can offer is appreciated... the
Sunday 6pm (EST) deadline looms :-(

 

[dearingkr]

Your 2 ethernet segments be on separate subnets.
for example:
Main network 192.168.10.x/24
Remote network 192.168.11.x/24

Help!

Both Cisco 1761 routers have built in T1 CSU/DSU ports.. the user guide mentions something about using a RJ-48 cable to connection from the routers T1 CSU/DSU ports to the Verizon demarc box close to where the router is sitting.. I'm wondering, would't I be able to use a CAT 5 RJ 45 cable from the router to the demarc box?? Since it has the CSU/DSU port built in.. Can anyone help point the way?? when I do a show int s0/0, it says that the serial link and also the serial protocol are both down.. I have both point to point routers now setup with -what I believe are RJ 48 cables I made from following a websites wiring scheme for RJ 48.. I someone can just tell me that I could get away with using RJ45 cables at both ends of the point to point for both routers,,, I'll be a happy man.. wishful thinking!

thx to all
gman

 

[dearingkr]

A standard CAT5 patch cable is fine.

[gman10]

Really Dearingkr.. is that all there was to it?? I spent hrs trying different things.. what started this whole escapade was that a fellow engineer started mentioning how I may need an RJ 48.. this is probably for a different assessment... thx's so much.. will try it again tomorrow at both sites..

gman

 

[gman10]

Hi Dearlingkr-

I spoke with the circuit guy atn Verizon, as it turns out ..he said that the demarc boxes from point to point do have RJ 48 port on them..should or could I still get away with plugging a CAT 5 RJ 45 cable from the routers csu/dsu t1 port to the demarc?? just curious now more than anything else..


thx gman

 

[lgarner]

You need a straight-through cable. The RJ45 connector on a UTP Ethernet cable is equivalent to the telco RJ48.

So, yes, Cat5 cables do work in lieu of telco cables. (Not vice-versa, of course.)

 

[dearingkr]

Correct.
The Verizon guy is talking in telco terms.
As far a the data world is concerned, a standard patch cable.

[gman10]

thx again guys.. this is what I've got, brand new rj-45 cables on both sides but serial 0/0 link and protocol still down on both sides.. I'm having Verizon check their circuit, called them and gave someone circuit ID.. If not, maybe powercycling the routers will help.. will give it a shot..

thx again.. learning is the BEST POLICY especially when it comes from experienced people!!

gman

 

[dearingkr]

Couple of things to check.

1. Make sure the port is not shut. Do a 'sh int s0/0'.
Make sure the status is NOT 'administratively down'.
If it is, then:
router# config t
router(config)# int s0/0
router(config-if)# no shut
router(config-if)# exit

2. Check the CD status light.
'CD' (Carrier Detect) should be lit.
If not, you've got a physical connection problem.

3. Check the AL status light.
'AL' (Alarm) should not be lit.
If lit, try the following:
First, save your config
router# wr
or
router# copy run start
Then 'reload' to reboot the router.

4. Loopback test (with ISP on the phone)
Make a loopback plug: Normally just a RJ-45 jack with the following pins jumpered together: 1-4, 2-5.

If you put the loopback in the T1 jack of the router, the interface should come up (looped). If not, you have a hardware problem.

The next step is to test the circuit. With telco on the phone, put your loopback on their circuit. They should see the loop.

Hope this helps.

Hi Dearingkr,

I haven't been able to get back to you sooner but you are correct, there was an AL light on..

I'll try your:3. Check the AL status light.
'AL' (Alarm) should not be lit.
If lit, try the following:
First, save your config
router# wr
or
router# copy run start
Then 'reload' to reboot the router.

I'll bet that should do it but I'll let you know when I get on site again.. as always, I appreciate everyones insight here!!

[gman10]

Hi Dearingkr,

My serials links are up, the AL was lit and did *wr and then reload which remedied the P to P assessement.. woo hoo!! One more twister for you if you have time..

Router B has a DVR (video recorder) that needs to be seen by Router A. I called the vendor and told me this can be accomplished by opening port 18772 for both TCP/UDP.. I assume I'll accomplish this using an access-list?

Also, I can ping the serial int address on router B from router A and vice versa but I can't ping the f0/0 address on router B from routerA and vice versa.. I need to check my EIGRP entries.. probably a typo on the EIGRP entries from either config..

Just wanted to thank you again for everything.. making great success!!

gman

 

[dearingkr]

Might be a typo, as you said.

Also:
router#sh ip route
on either router should show all subnets.
