HP VSR1000: How to configure a IPsec tunnel

One possible use case for the HP VSR1000 is to build IPsec tunnels for secure data transfer. In this post I will show you how to configure a IPsec tunnel between two HP VSR1000. If you need a short introduction, feel free to take a look at this article. The experimental setup We have two server VMs (in this case Windows Server 2008 R2 with SP1) and two HP VSR1000 Virtual Service Router.

How to deploy Cisco CSR1000V & HP VSR1000 Virtual Service Router

In an earlier blog post I wrote a bit about virtual service routers. Now I want to show you how easily you can deploy a virtual service router in your lab. To do so I have downloaded the the HP VSR1000 Virtual Service Router and the Cisco Cloud Service Router 1000V. If you want to know how to download them, just read the mentioned blog post. Because both virtual service routers delivered as OVA, I can easily deploy them through the vSphere Client (sorry, no Web Client.

Virtual Service Router - An introduction

Today you can get nearly everything as a virtual appliance. So even a router. Usually virtual router appliances are used for the same purposes as physical router: Connecting different networks. A router is nothing more then a piece of hardware and software. Due to this fact a router can be easily deployed as a virtual appliance. So where do you find router typically? In you datacenter? Yes, but in a datacenter you will deal typically with layer-3 switches rather than a classical router.

Flooded network due HP Networking Switches & Windows NLB

Today I was onsite at a customer to bring a tiny VMware vSphere cluster to life (HP BladeSystem c7000 with 7 HP ProLiant BL460 Gen8). Normally no big deal, but it started with two unavailable Onboard Administrator (OA) network interfaces. I switched from static ip addresses to DHCP, but I had no luck. I noticed that both interfaces were available if I connect my notebook directly to the interfaces. I even noticed that the Insight Display was unresponsive after connecting one or both OA to the network.
