Site-to-site VPN tunnels between Meraki MX and Cisco ASA
As I wrote on my recent post here, I was involved into a project to implement a Meraki MX into the Azure Cloud. This project also includes a migration phase…
How to deploy a Cisco Meraki vMX100 into Microsoft Azure
Recently, I was involved into a project where we had to deploy a Cisco Meraki vMX100 into Microsoft Azure cloud and build site-to-site and clients VPNs.
The setup process on Azure is relatively simple, however, I lost quite a lot of time on basic issues because the documentation provided by Cisco is not 100% accurate. Here are some tips and tricks to save you time.
BGP full-routes vs partial-routes vs default-route
The IPv4 full BGP table size is at around 725000 prefix now. This may cause problems for companies who do not have the resources to update or upgrade their edge routers.
But, except for Internet transit providers, who does really need to get the full IPv4 BGP table today? And what are the alternatives? Let’s see that in details with some use-cases.

BGP load sharing and unequal cost load sharing
On Cisco routers, by default the BGP protocol will not do load-sharing – and even less unequal cost load-sharing – across multiple links, for traffic to the same eBGP destination with different AS-path. Let’s see how we can change this.
6 CCIE strategy mistakes
I passed the CCIE R&S written exams version 4.0 and 5.0, studied for the lab exams for both versions with workbooks and mock labs from many vendors such as INE, IPexpert (closed today), Narbik Kocharians / Micronics Training and Cisco expert-level training. I attempted the CCIE R&S lab exam once on version 4.0 and three times on version 5.0. Now I would like to share with you my experience about the CCIE strategy and especially the mistakes to avoid to have the best chance to get your numbers.
Cisco Embedded Event Manager (EEM)
The Cisco Embedded Event Manager or Cisco EEM is a software component of Cisco IOS, IOS-XR, and NX-OS that provides real-time network event detection and onboard automation.
EEM allows you to automate tasks, perform minor enhancements and create workarounds and can makes life easier for network operators by tracking and classifying events that take place on a network device and providing actions options for those events.
Cisco Flexible Netflow configuration
Recently, a customer called me to configure Netflow on these routers because he just installed NetFlow Analyzer software from ManageEngine. This software is an “all in one” NetFlow collector, database, WebUI software, able to build pretty nice reports.
In my opinion, Netflow is one of the absolutely required software to have a good visibility when you operate a network.
