Ah July. For me in the Northeast, that means beach weather, backyards BBQs, and the 4th of July.
As many of you know the 4th of July, America's Independence Day, traditionally calls for fireworks. Well, for today's Feature Friday, I wanted to discuss with you the feature that creates the most fireworks in the routing world: Secure Vector Routing (SVR) (sorry, couldn't help it).
Secure Vector Routing (SVR) Overview
Secure Vector Routing is a protocol that two Session Smart Routers (SSRs) use when they are sending traffic back and forth to each other. The best part of SVR is that it provides Security (through encryption, authentication, and NAT) without adding additional headers to packets, unlike tunnel-based protocols, such as GRE and IPsec.
Secure Vector Routing enables security without additional headers through a metadata exchange between two SSRs. This is basically like a secret message that is passed between SSRs sharing information such as:
We'll get into this more next week. But to learn more about the metadata exchange now, check out this article.
There are many benefits to using SVR over a tunnel-based protocol, but just to name a few:
To learn more about the downfalls of tunnel-based protocols and why we avoid them, take a look at these resources:
Well, that's it for now. We're keeping it short this week as next week we will dive into SVR part two: Packet Walkthrough. In the meantime, let us know what's on your mind!
Huge shot out to @Justin for pulling together these #FeatureFridays posts. If you find them interesting/helpful/validating and want Justin to keep publishing #FeatureFridays posts, please let Justin know by clicking the "Recommend" button at the top of each post.
Also in the spirit of community and shared learning, Justin asks questions at the bottom of each post. If you have experience with the feature Justin mentions, reply and share your practices and perspectives.
One of Justin's question ☝️ was "Where is the best place to see Fireworks on the 4th of July?" I am from a town (Mandan) in North Dakota where they allow you to shoot off fireworks (if there are not drought conditions.) There are huge fireworks going off for hours all around you. Wonderful if you like fireworks, but not so great for those with PTSD or pets.
