Answer to Gandi BGP problem stuff

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.

Blog deserted : some news

This blog seems deserted since one or two months. There are some reasons about this. First of all :

The death of my mother. 14 months after my father, she is gone… I don’t have enought words and want to talk about it here.
God bless them and gives us a little happiness in these dark times of life (The grandfather of my wife also died in the last two weeks).

Cisco Learning Labs

There’s some new stuff in Cisco world. We are now able to access Cisco-Labs directly there. These labs are planned to fill the pratice in certification. The official page is here. I think I will use it when MPLS Cert time will be there…
Lab 2-1 Establishing the Service Provider IGP Routing Environment Lab 3-1 Establishing the Core MPLSEnvironment Lab 5-1 Initial MPLS VPN Setup Lab 5-2 Running EIGRP Between PE and CE Routers Lab 5-3 Running OSPF Between PE and CE Routers Lab 5-4 Running BGP Between PE and CE Routers Lab 6-1 Overlapping VPNs Lab 6-2 Merging Service Providers Lab 6-3 Common Services VPN Lab 7-1 Establishing Central Site Internet Connectivity with and MPLS VPN Lab 8-1 Implementing Basic MPLS TE Real interesting labs, aren’t it ? You can access/read an interesting point of view on @etherealmind website here.

Preparing to @packetlife lab

To take a @packetlife lab (community lab), I prepare a little scenario about BGP and other features such as :

  • Route reflectors
  • BGP confederations
  • BGP dampening
  • ORF (Outbound Route Filter)

My lab looks like :
Level 2 :

Level 3:

A thought for the missing

In this day of 29 March I have a thought for all the missing people missing horribly on those who remain on this earth. I thought this day for my father who died last year, but I think of him every day. May God bless you.
Life must go on, but it’s not the same without you. But I hope it will bring pleasant surprises to change.
