OSPF: Type-1 vs Type-2

Image
OSPF: Type-1 vs Type-2 Type 1: Considered close to the AS. Metric is based on the sum of the internal and external costs. Type 2: Considered far away from the AS. Metric is based on the external cost only.   OSPF router prefers a type 1 external router over a type 2.   Each external route is assigned a metric. There are two types of external-route metrics. A type 1 metric is the sum of the external cost plus the internal cost to reach the ASBR. A type 2 metric is only the external cost (the internal cost is not considered). If there are two external routes to the same destination, one type 1 and one type 2, an OSPF router selects the type 1 route over the type 2 route. That is represented in E1 and E2.

Shut down those VMs firstly before running this command then bring them back up later. Turn on SSH and log in to the host. Remove the current license rm -r /etc/vmware/license.cfg Copy over the new evaluation license, which is already on the host cp /etc/vmware/.#license.cfg /etc/vmware/license.cfg Restart ESXi services /etc/init.d/vpxa restart Confirm the new license Automatic Script The commands above can be run automatic to keep your ESXi license reset on a set schedule using cron. I have also created a script which powers off and on a VM of your choice (such as a UPS agent) in case it shuts down the host. First create the script (reset-eval.sh) somewhere accessible to ESXi. I chose to put in my ZFS0 datastore (/vmfs/volumes/ZFS0/reset.eval) #!/bin/sh #...
