After a long period withouy working on my CCIE study, I will now plan and work hard toward this objective. I will try to explain, write about my journey toward CCIE Routing and Switching written exam.
Be prepared to read new content about Cisco, CCIE and telco here.
Best regards, Christophe
Here it is a little challenge. You will find two CPE connected to two different PE. The two CPE are used in “fail-over” model by using HSRP. The two CPE dial on PE. CPEprimaire dials through a Bridge, CPESecondaire dials directly.
CPEPrimaire :
-------------
on LAN fastethernet:
standby 5 ip 10.0.0.1
standby 5 preempt
standby 5 track Dialer 1
standby 5 priority 105
CPESecondaire :
---------------
on LAN fastethernet :
standby 5 ip 10.0.0.1
standby 5 preempt
Just to give you a new challenge. It is supplied by IPexpert.

Have fun with this new challenge. For real, it is not really hard ;)
In reading Cisco France blog, I have discovered this platform : ASR903.
Thank you for the blog post from Jerome Durand (Cisco) about IOS-XE (v3.5) which will be running on ASR903. This piece of hardware is not already sold by anyone, even Cisco. This router seems really powerful in a compact place in your rack. Read it :

I have received at work this Cisco Small Business units to test it b efore we can sell it to customers. It seems really well. It is well designed (some linux distro is behind), and customized. I love all these features and smart/quickly applied and in action. UC320W is a good prodoct for Small business office. |

It is not really easy to explain BGP/ASN concepts to a non-friendly-IT friend. I am really interested in how you explain this. Just to know. I am really curious. Do you use an analogy ? Which ? Do you go directly in technical stuff ? To begin : for my part I use an analogy around city/country. I explain that city/country announce to others her streets or better a set of streets. and so on … It could be cool to know your stories about this… |

It is not from me, but I find this challenges really interesting … - challenge-1 - challenge-2 - challenge-3 - challenge-4 - challenge-5 |

I really like ipexpert content (blog). I think I will use some of their stuff, when CCIE R&S Written and lab journey will begin (after CCIP and last exam : 642-642 (QoS)).
Some new toys (C7201 and C6506/sup720) to deploy in different datacenters :)

Yesterday, I received the first one of a CCIE book’s series. So, I received : “CCIE Routing and Switching (certification guide)”. 1080 pages to study networking technologies deeper toward CCIE Written (350-001) exam. I can’t wait to open this book and other (TCP/IP vol 1 and 2 (to buy)) to study. But before, I must finish Qos Exam (642-642), the last part of my CCIP studies. After reading table of contents of CCIE cert guide, I am really happy to have choosen CCIP course before test my knowledge against CCIE… |

| Qos, MPLS, BGP studies/knowledge acquired during CCIP will be great appreciated for CCIE studies :) |
To answer to BGP problem about BGP and static route (big subnet) to Null 0 : http://lacuisinedegandi.net/post/2011/06/20/Quand-Null0-et-BGP-peuvent-causer-probleme.
A solution can be :
R2#sh run | inc track
track 10 ip route 217.169.255.1 255.255.255.255 reachability
ip route 217.169.240.0 255.255.240.0 Null0 track 10
Where 217.169.255.1 would be IP of loopback IP address of an iBGP/Transit eBGP router. So that, if it is unreachable, static route to 217.169.240.0/20 will be removed and announcement to an eBGP neighbor will not be sent.
