I have implement a few DMVPN solutions recently and I thought that a post about dual DMVPN hub with dual DMVPN network would be interesting. I will describe the configuration for a DMVPN solution with dual hub and dual DMVPN network. Below you will find the network diagram for this solution. Here is a […]
Read MoreVCA6-NV – Virtual switches
In this post, I will try to identify and explain the concept of vSphere Standard and Distributed virtual switches. What’s a virtual switch ? A virtual switch is similar in concept to a physical switch. VMs are connected to the virtual switch using a “virtual wire”. Uplinks are used to connect the virtual switch to […]
Read MoreVMware NSX – How to get hands on labs
Well it is easy to find documentation, get the admin guide but nothing is worth than practicing when you really want to get knowledge on something. When working with Cisco routers and switches, you can easily find tools like GNS3, packet tracer to practice. With Cisco VIRL it’s even easier to practice, test and […]
Read MoreVMware NSX – VCA6-NV exam details
You can find the exam details with the blueprint on the following link : https://mylearn.vmware.com/mgrReg/plan.cfm?plan=64577&ui=www_cert The VCA6-NV exam is about network virtualization using VMware NSX. The exam itself is not that expensive compare to what I get used with Cisco and it can be done online. Even if this exam is not a pre-requisite […]
Read MoreIPv6 – Advanced EIGRPv6
Back to IPv6, this time for more advanced configuration. In this post I will focus on EIGRPv6. IPv6 – Advanced EIGRPv6 –Network Diagram: IPv6 – Advanced EIGRPv6 – configuration: I have already setup the basic EIGRPv6 configuration, which means that all the routers interfaces are part of EIGRP 100. From SW51, we […]
Read MoreVPN technologies – DMVPN – Phase 2
Following my previous article on DMVPN phase 1. This time I’m going to configure DMVPN phase 2. In phase 2, we will be able to dynamically build spoke-to-spoke tunnel. VPN technologies – DMVPN – Phase 2 – configuration: The configuration needs to be changed on the spoke routers. The tunnel mode needs to […]
Read MoreVPN technologies – DMVPN – Phase 1
Starting a new series about DMVPN. In this post, I will configure a basic DMVPN network, with one hub and 2 spoke sites. Here is the link for the cisco documentation about DMVPN: http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/sec_conn_dmvpn/configuration/15-mt/sec-conn-dmvpn-15-mt-book/sec-conn-dmvpn-dmvpn.html And the link for everything related with NHRP: http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipaddr_nhrp/configuration/15-mt/nhrp-15-mt-book/config-nhrp.html And one very good article from INE with very […]
Read MoreVPN Technologies – MPLS-L3VPN – PE-CE routing OSPF EIGRP
In this post, we will connect a new customer (Customer2) to our MPLS backbone. Router CE21 will be connected to R5 and we will use OSPF as the PE-CE routing protocol. Router CE22 will be connected to R7 and we will use EIGRP as the PE-CE routing protocol. Here are the links to […]
Read MoreVPN technologies – MPLS-L3VPN – PE-CE routing
In this post I will add a customer to the MPLS-VPN network. Customer1 will have a router connected to R5 (CE11) and a second router (CE12) connected to R6. VPN technologies – MPLS-L3VPN – PE-CE routing – configuration: VRF configuration: First we need to configured a VRF for our customer on all the PE […]
Read MoreVPN technologies – MPLS-L3VPN – MP-BGP
In this post, I will focus on configuring MP-BGP which is the protocol used between the PE router. VPN technologies – MPLS-L3VPN – MP-BGP – Theory : This is the link to the Cisco documentation for configuring MPLS-VPN. http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/mp_l3_vpns/configuration/15-mt/mp-l3-vpns-15-mt-book.html MP-BGP should be configured between the PE routers and is used to advertised the […]
