Super Cisco Rookie - frame relay help + vty config

[wwwmario]

Hello everyone,

I spent some time looking through almost all the featured threads; learnt alot but not enough to come up to a solution for my config... here's my problem:

need to establish connectivity with remote customer staging network; they sent here an empty 2503, a DCE cables and stuff along with telco DLCI info (mine is 200; remote is 100).

We agreed on IP addressing (192.168.255.8/30; mine .9, remote is .10), and encap/lmi (IETF/ANSI).

Thanks to the forum and other resources, I did setup the 2503 in all the relevant parts but the I got stuck on the WAN config..

This is the conf for the s0:

interface Serial0
description WAN to e-Press remote router
ip address 192.168.255.9 255.255.255.252
no ip directed-broadcast
encapsulation frame-relay IETF
bandwidth 256
no fair-queue
frame-relay interface-dlci 200
frame-relay lmi-type ansi
frame-relay map ip 192.168.255.10 100 IETF

From what I found on the forum it seems to me that the "frame-relay map" command and (guess) the subinterfaces fit into my problem somewhere, but.. aaaargh!

Thanks in advance to anyone who'll help (and to those who'll not as well

Second (silly) problem:

I got a 2501 as well that I'm just using as a playground;
it's coming from my company past history; managed to recover
password and reconfigure it & everything.

in the vty config-line, it shows 0-178 as possible range;
during the bootstrap I get a warning that so many vty lines
degrade performance (and who needs them anyway?)...

searched cisco.com & wherever, but can't find how to set them back to default, which should be 0-4, right?

Any advice is warmly welcome.

Ciao

Hi man & thanks,

actually I see you create a subint for s0 (I think the common practice is to set the subint # to recall the DLCI # for convenience); but then I don't follow anymore...

from what I read subint allow for multiplexing, but here there's just one PVC between me and the remote router,
is it best to create subint anyway? how does they work?

thanks

There really isn't any difference if you just have one PVC to created a subinterface vs. using the entire interface. But, created the subinterface is a much better solution in terms of future expandability and is easier(in my opinion). So, you can set it up anyway you want, but I would recommend the using the subinterfaces.... Hope this helps...

There are a few errors in the commands due to my rushing during lunch but you grasp the ideas. You can find sample configs such as the one above on cisco web sight. You will find allot of samples for static and dynamic addressing etc. Route once; switch many

Thanks to all of you guys,

actually it turned out that my understandings of Cisco world and fram-relay were correct.

Two major problems weren't helping me at all:
1) they guy managing the remote router
2) Fux@#?!! italian telco who inverted DLCIs...

We made a real time trial and error to point out that and now they works.

Got other problems with routing now and still don't know how
to reduce the number of vtys... :-(

Just an FYI here. Actually the DLCI's probably weren't backwards!! In your original post you stated that (mine is 200; remote is 100). When you program the dlci on the interface you tell it what is the other end that I'm to connect to. So the carrier was correct to say yours is 200, then your router would need to be program as &quot;frame-relay interface-dlci 100&quot;
and reversed on the other end. Just my 2 cents worth

Hey tadiman!

you know, this is (4 me) a great FYI!

now I know for the future!
...so hard 2 enter this cisco famiglia..

I thought mine was mine and so on.

Thanks!
