Frame-relay switch config - frame-relay intf-type dce

Hmm... I was entering the config for my frame-relay switch, and started getting this error;

'route command not allowed between two DTE interfaces'

Which was particularly annoying, as I only had a single DTE interface connected (still waiting on my remaining DB60-DB60 cables to arrive..)

A quick google led me to a forum which stated you must enter the following command;

'frame-relay intf-type dce'

For each interface on your frame-relay switch..


This command was accepted fine. What I failed to do (facepalm!) was to then re-add the route commands that had previously been rejected, so I spent a good 10-15 minutes troubleshooting why my circuit would not come up.. Once the routes were re-added, everything went swimmingly!

HyperTerminal - send break

Useful note for using HyperTerminal -

to send a 'break' whilst a device is booting (to get into rommon mode), press 'Ctrl + Pause/Break'

Lab update

I've had to move my lab this weekend (it has to make way for the Christmas tree!), so I decided to re-cable it to the INE CCNP Bootcamp topology. I've also ordered the final(ish) bits of kit that I need to complete it all - 2x WIC-1T and another NM-4A/S/

The lab now (once outstanding orders arrive) consists of;

R1 - 2610xm w/ WIC-2T
R2 - 2610xm w/ 2x WIC-1T
R3 - 2610xm w/ NM-4A/S
R4 - 1841 w/ WIC-2T
R5 - 2611xm w/2x WIC-1T
FR switch - 2611 w/ NM-4A/S, 2x WIC-1T

I'm just going through them all now to configure with a 'Management' address so I can always telnet to each device (I don't have an Access-server)

Argh! It's been a week already..

Ok, nearly a week.. It's been quite a busy one, so that's my excuse for not studying / blogging much. Here's an update on what's happened this week;

  • I've watched two and a half of my CCNP Bootcamp CoD videos.. An introduction to ISCW and ONT, Basic Teleworker Services, and half of an MPLS Overview.
  • The Lab Workbook has now been updated to include ISCW and ONT, which is nice. See here
  • I've gone ahead and ordered a NM-4A/S and 2 x WIC-1T to put into a 2611 (that belongs to a friend) and use as my Frame-Relay switch. I have a 2610XM that is not being used, but I still need 2 x serial connections to use it as R5. I may end up purchasing a router that comes with a WIC-2T to use as R5, and then if my friend ever wants their 2611 back, I shouldn't be short. The problem is i've already spent a huge amount of money on my study in the last 2 months, and Christmas is around the corner, so i'm a little anxious about spending more just yet..
  • We've had a shuffle round at work, so i'm hoping to get a bit more 'discreet' studying done! (maybe even a few runs of CoD videos)

Internetwork Expert CCNP Bootcamp Class-on-Demand, first impressions

Just finished watching the first two parts of ISCW videos, which is Day 1 of the 2nd Week of the Bootcamp.. ;) Yes, i'm not planning on going through the videos in the recorded order, as i'd like to get ISCW exam done first. My logic being, that i've (fairly) recently completed my CCNA:Sec exam, and there's a large amount of overlap between that and ISCW.

The first impression is that the videos are very good. I was a little concerned by the free videos available that I watched before purchasing, not because of the content, but because of the quality. I was a little worried about how INE would deliver their proper content (the free stuff is on YouTube), but it has turned out very well. You can see the instructor's screen, any questions that were asked by the people taking the class live, and links to the related documentation. You can also actually click on the links in the slides/videos which then opens up a new browser window <- very clever as it's something I don't think can be done with normal video hosting.

The Lab Workbook is a little unfinished - as of today only listing BCMSN and BCSI, but i'm sure ISCW and ONT will turn up.

I'm still not decided how I will continue with my studies. I'll definitely be watching the INE videos, but i'm not sure how I will integrate these with my CiscoPress reading etc. The INE Lab Workbook also uses a slightly different set of equipment to the CiscoPress Lab Portfolio (one more router and a Frame Relay switch), so I may have to look at purchasing those.. After Christmas I think! :)

Spent some money..

I've spent some more money on my pursuit of CCNP / CCIE certification status.. Internetwork Expert's CCNP Bootcamp Class-on-Demand

I'm just watching one of the Introduction videos now. I'll post a few review/write-ups as I go!

Testing from my iPhone..

Just testing out blogging from my iPhone.. Seems easy enough, although I can't see myself writing too many essays from this!

Configuring PPPoE

Grrr.. I've been trying to set my 2611XM up to act as PPPoE server, so that I can test my PPPoE client config, but it's not been going well.

The client config is fairly straight-forward;

interface Eth 1
no ip address
pppoe enable
pppoe-client dial-pool-number 1
interface Dialer 0
ip address negotiated
ip mtu 1492
encapsulation ppp
dial pool 1

And i've found a few posts online about configuring a PPPoE server on a Cisco router, but not had much luck implementing it. I can get as far as creating a VPDN-Group, but my router does not accept PPPoE as a protocol.

The PPPoE / PPPoA server config is not actually covered in the ISCW Lab Portfolio (it only shows you how to configure the client) but I thought it would be an interesting exercise to try..

The other parts covered in the ISCW Lab Portfolio (and a few bits that I think are missing) are;

interface Eth 0
ip address
ip nat inside
ip tcp mss-adjust 1452
interface Dialer0
ip nat outside
ip nat inside source list 101 interface Dialer0 overload
access-list 101 permit ip any
ip dhcp pool LOCAL
default router
ip dhcp excluded-address
ip route Dialer0


2600's take ages to boot.. :(

Edit: Grrr.. and even more annoying when you power-on the wrong one!!

Goals from last week (w/c 2nd Nov 2009)

  • Receive final router for Lab - complete!
  • Finish cabling Lab - complete! (although being the anally-retentive person that I am, I may re-do 2 cables, as they don't match the others.. 1 because I forgot to put on the boot, and another because I wanted to patch something and couldn't be bothered to make a cable myself!)
  • Read first 2 Chapters of ISCW Exam Cert Guide - complete!
  • Complete Chapter 2 of ISCW Lab Portfolio - i've not actually done this.. But I have done parts of Chapter 3 instead. I think i'll re-think the way in which I work through the book.

Woohoo! Lab is (pretty much) complete!!

I picked up my 2611xm from my parents, along with my 4 SS-DB60 cables, so my Lab for the ISCW now consists of;

1 x 1841 w/ 2x WIC-1T
1 x 2611xm w/ 2x WIC-1T
1 x 2610xm w/ 2x WIC-2T
1 x 2610xm w/ 2x WIC-1T
1 x 2950 12-port

The ISCW Lab Portfolio is actually based on 4 x 2811 routers, which are obviously really expensive! 2811's have 2xFE ports, whereas my 2610xm's only have the 1.. I'm hoping this won't be too much of an issue, but i'm also tempted to buy a pair of 2621xm's that i've seen on eBay as I intend on carrying on with the CCIE in the future.

I quickly ran through a basic lab on configuring a GRE tunnel and setting up EIGRP, nice and easy! Will probably run through it again, and actually read the notes that go along with it..

Update (w/c 2nd Nov 2009)

An update on the goals for this week;

  • Receive final router for Lab - i've had delivery confirmation, I just need to collect it from my parents (Thurs).
  • Finish cabling Lab - I spent some time this evening creating 0.5m Cat5e cables, and I believe my Serial cables have arrived at my parents.
  • Read first 2 Chapters of of ISCW ECG - I went through the 'Do I Know This Already' questions for Chapter 1, and scored 7/8 so think i'll skip most of this chapter. Not started Chapter 2 just yet.
  • Complete Chapter 2 of ISCW Lab Portfolio - not started..

CCNP changes being announced Jan 2010

Ok, so the changes that I expected to be announced in Nov 09, are no being announced in Jan 2010.. - https://learningnetwork.cisco.com/thread/8498

This is kind of good news, as it means I should be able to get a good start on one of the existing exams, and get it out of the way before the announcement.

Hello, and welcome to blog.123and6.com. Make yourself at home.

I guess this first post should introduce myself, and explain a litte about what blog.123and6.com is all about. Well, for about 4 years now I have worked in I.T. and about 2 years ago I passed my first Cisco networking certification - the CCNA.

Technology has always interested in me, and it was actually by pure chance that I ended up working in the field of networking. But since I first started to understand what was going on, i've wanted to learn more.

The 'holy grail' for Cisco networking engineers is the CCIE or Cisco Certified Internetwork Expert. This includes a written exam, and what started out as a 2-day lab exam. The Lab has changed a lot over the years, became a single 8.5 hour day, and as of 19th Oct. 2009 includes a 2-hour 'Troubleshooting' section, leaving the actual config down to 6.5 hours.

I'd like to think that i'll get there one day..

At the moment my record stands at;

CCNA - Passed
CCDA - Failed :(
CCNA:Security - Passed
CCVP: CVoice - Failed :(

I am in two minds as whether to take another crack at the CVoice exam (I only narrowly failed), or to start with the CCNP. Over the last couple of weeks i've built up a lab that should see me through most of the CCNP, but as usual the problem will be the time constraints of having a full-time job, a girlfriend, moving house.. Plus there's the expected announcement from Cisco that the CCNP track will be changing soon.

But anyway, stay tuned for irregular posts on Cisco networking and my travels through the certification world..
