I was wondering what choice to make concerning the photo part of this blog... Two options here. First on is to add a photo section to this blog and mix it with all the other stuff. The main advantage of doing this is obvious only one place to manage and maintain. In terms of SEO no need to tweak another website to have a "not-so-bad" ranking. The main problem is that this theme is not adapted for photoblogging. The second option is to dedicate ...

I had a series of articles on the old version of my website on the Cisco aNCE recruitment program - Cisco website link - I didn't think it was useful to copy them here but finally it looks like quite a few people are still interested in this. What is the Cisco aNCE program Cisco aNCE program is a 8 month long program based on the Cisco model of education (Education, Exposure and Experience). The idea is to shape the participant to the Cisco ...

Since I've redone the whole website I'm getting lots of 404 errors which is expected. What I was less expecting is the 404 errors in Google webmaster tools for the new URLs!! It looks like Google tries to get the URLs that are folders with an "index.html" at the end. For example even though http://www.remiphilippe.fr/2010/04/29/bgp-send-label-in-inter-as-scenarios/ is in my sitemap Google will try to get http://www.remiphilippe.fr/2010/04/29...

When playing with the MPLS Inter AS options I was obliged to use the neighbor x.x.x.x send-label command to exchange my label information between to AS. the interesting thing is that depending on how I was send the PE loopbacks in BGP I could loose connectivity between CEs. Lets play around with the send-label command to see how it really works. I built a 6 router topology in 2 AS's has shown in the following exhibit. (more…)

A think you may want to know and that I discovered when playing on a device is that VRF needs CEF (ok that's not new) and actually it won't let you do it. The tricky thing is that if you create a VRF without CEF on older version of IOS you don't get this and when you enable CEF AFTER having configured the VRF it won't work. You'll have to reboot the router for the routing to work in the VRF.

Internetwoking is a feature on L2VPN that makes possible to connect an ethernet interface to a frame relay interface for example. Not sure if this is in the scope of the CCIE but I fell on it while studying L2TPv3. We are going to configure an internetworking between R1 and R9, R1 will be on ethernet and R9 on frame relay. The topology is still based on the CsC topology with an added router R9 running frame relay with R7. (more…)

As you know there are 2 types of levels in ISIS Level 1 and level 2. A router can be in one of these 2 types of level or can be a L1/L2 router (kind of ABR). A router L1/L2 set an ATT bit to indicate to routers in L1 a default gateway, whereas a L2 router will have all the more specific route. In some case you'd like to have all (or a subset) of the L2 routes in L1. To do this you can redistribute from L2 to L1. (more…)

Same as for L2TPv3 we'll go over the basic configuration of an AToM tunnel. In this example we'll only do ethernet to ethernet. We'll go in internetworking in another post. As for L2TPv3 we'll use the CsC configuration to setup our tunnels between R1 and R8 To manage this interconnection we’ll be using the interface G1/0 of R2 and G2/0 of R7. (more…)

L2TPv3 in a L2VPN technology, we're going to have quick look on how to configure it. For this example I'll be using the CsC topology to interconnected R1 and R8 To manage this interconnection we'll be using the interface G1/0 of R2 and G2/0 of R7. (more…)

As usual when you study CCIE you need to know at least 2 ways to do everything, same for Carrier supporting Carrier (CsC). I know that InterNetwork Expert they say that the chances are slim to have MPLS VPN Carrier supporting Carrier but you never know, it's not the biggest bit of study anyway. MPLS VPN Carrier supporting Carrier Lab Topology So for our setup I'll be using a 8 router setup AS100 will be our super service provider provid...
