We will look at how to configure Cisco DMVPN phase 1. Further more we will run OSPF routing and everything will be encrypted with IPSec. What is DMVPN DMVPN is a combination of protocols (GRE, NHRP, IPSec etc.) which facilitates  to create a HUB-And-Spoke overlay network with minimum configuration effort. Or we can archive a fully meshed network (phase 3) with minimum effort. For theory and get an idea of how everything works, I recommend reading  In-depth look at Fortigate's ADVPN - Part I and  In-depth look at Fortigate's ADVPN - Part II , where the theory behind underlay network is almost same. The difference is Fortinet uses proprietary extension of IPSec protocol and Cisco uses proprietary implementation of GRE and NHRP. One can also do a Google search to get an idea about how DMVPN works. In this blog post, we will configure DMVPN Phase 1 which means that from routing perspective, our network will work as hub-and-spoke topology. All the communication...

I found it very difficult to find the actual configuration steps that is required for 802.1x authentication in Huawei's VRP based switches. Huawei have two authentication modes - unified-mode and common-mode . I did not find any straight forward configuration guide on how to configure 802.1X in unified-mode . In today's blog article I will just try to address that. In this blog, I will just cover Huawei VRP based switches's configuration commands in unified-mode authentication for 802.1x. I will not present a network topology and work with that. If someone is interested about a full network setup and example, I recommend reading part I , part II and compare the configuration accordingly. Verify authentication mode First we will, check for current authentication mode the switch is running. If it is running "common-mode", we need to change it to "unified-mode" . Changing authentication mode requires a restart of the switch. [sw] display au...
