Cisco 2600 router - Still can't get VPDN + PPPoE to work - no "vpdn enable" command

Posted on 2008-10-14
Last Modified: 2012-05-05
I am at my wits end with this.  I have been hours at this config and haven't even started because I can't get an IOS loaded that supports "vdpn enable" and "protocol PPPoE".

I am following this tutorial to connect to my new ISP:

It begins:

vpdn enable
no vpdn logging
vpdn-group 1
protocol pppoe

I have been using the IOS selector to try and find the correct image (thanks to a previous question), but it seems to be telling me lies because none of the ones I try seem to give me the "vpdn enable" command.  Someone who knows what they are doing please help me get this working.  Attached is a list of the IOS versions I have tried and a "show version" output.  I have 16MB flash.

ADSL, or T1 thorough the 2600?

I'm not sure if it is technically called ADSL or not.  

The ISP fiber comes into the demarc and then patches to a media converter with an ethernet port for my router.  I have a username (email) and password to connect.  I can connect an XP laptop with the connection wizard and the PPPoE option.  Sorry if that was too verbose...

Example for ADSL/equivalent

Here's what i'm using for my T1:
interface FastEthernet0/0
 ip address 74.x.x.x
 duplex auto
 speed auto
interface Serial0/0
 bandwidth 1500
 no ip address
 encapsulation frame-relay IETF
 no ip mroute-cache
 no fair-queue
 service-module t1 timeslots 1-24
 frame-relay traffic-shaping
 frame-relay lmi-type ansi
interface Serial0/0.16 point-to-point
 bandwidth 1500
 frame-relay interface-dlci 16 ppp Virtual-Template1
interface Virtual-Template1
 ip address negotiated
 ppp chap hostname <username here>
 ppp chap password 0 <password here>
 ppp ipcp dns request
ip classless
ip route <isp route>

Your ISP didnt give you a config?

Well, I don't think this should be very complicated.  Looking at the tutorial in my original post, we are talking about 10-15 commands if they would just work correctly.

I noticed you havent tried any c2600-is-mz which is the "IP Plus" for 12.2

You have only 48mb of DRAM, so you cant run the 12.3 versious of "IP Plus" (so named c2600-is4-mz, c2600-is5-mz)

Do you have access to the IP Plus image?

Actually,  I did try an is-mz from 12.3, but it was too big to run.  For some reason, I calculated my DRAM at 64MB so I got some practice using rommon> .  That sucked.

I will try what you have suggested.  Is IP Plus the feature set I should be looking at?  Maybe my problem is that I don't have enough memory here and there to get the features I want.  Can you upgrade these things?  Something tells me that isn't really an option.

Thanks for that link, it is exactly what I would like to do when I get these commands working.

Yes, you can upgrade. The modules are fairly cheap, good place to get them is eBay.

c2600-is-mz.122-27.bin is probably what you want. I have this IOS if you need, you can email me.

You can see in your sh ver command that it has 48MB memory (4mb is reserved for IO)

I always reload my IOSes from rommon mode, you are doing it another way?

I am using "copy tftp flash" which starts a sort of wizard that asks for the tftp server and filename and will erase the contents of the flash before it starts copying.  It's so much better than setting all those rommon uppercase variable names everytime.

I have access to that IOS, but I really appreciate the offer.  I am on my way to try this version.

eBay here I come!

12.2 is-mz requires 48MB, you can run that.
12.3 is-mz requires 64MB, you cant run that with your current rig.

12.2-is-mz doesn't work.  I tried a few other is-mz and they didn't work either.  I guess I am going to have to get with my ISP.  I bet they are going to tell me "good luck buddy" or "$75 / hr".

I tell you, I don't want to be a farmer, but it would be way less stressful.  How often does a cow just not work?  Bluh on cisco...

Do I need to know how to do this PPPoE config for the CCNA exam?

12.3-is-mz doesn't have it either.  It does give me the option to turn on PPPoE on the interface so that is closer than I have been.

Does anyone know what the feature I need is called in the IOS selector?  There are tons of options involving PPPoE.

I discovered that I needed the "telco" feature set.  I think a big problem with my setup is my limited flash (16MB) and limited RAM (48MB) on my 2621 router.

I am using c2600-telco-mz-123.22.bin
