VMware NSX Security Features – Who should pay for them?

One of the typical questions when considering NSX deployments is who should be the administrator?  However this is often a two horse race, between Network and Virtualization Systems Administrators.

nsx lab -Configure dynamic routing protocols: OSPF

In the last post we configured static routes so the vm web-1 172.168.10.10 could reach the external layer 3 router 192.168.100.1 Static routes are probably going to be exceptions, and most deployments will use a routing protocol. In this post we are going to configure the following OSPF areas and mappings If you haven’t be […]
