In this segment, Scott explores data center scenarios for Generic Routing Encapsulation. How GRE works and the requirements for GRE tunnels are presented.
- [Instructor] If we're going to create an environment…where virtual network segments can move…from one physical location to another,…we're going to need a way to redirect…their IP traffic on the fly.…And one of the most widely accepted ways to do this…is through the creation of tunnels.…Probably the most common use of tunnels…is virtual private networks, where private,…internal network traffic is encapsulated in communication…over a very public medium, most often the internet.…
In this case, encapsulation provides encryption…and probably employs one or more types of authentication…to protect your data and its path.…Generic route encapsulation uses the same basic concept…of encapsulating one network packet inside another,…but with different goals in mind.…GRE doesn't have any encryption or security built in.…It's designed to create routes to dynamic…virtual subnets within a controlled environment,…where security is not the concern.…
Consider this scenario.…It's common for many business workflow applications…to have a front-end server that provides the interface…
