BGP LABELED-UNICAST ON JUNIPER ROUTERS (FOR JNCIE-SP STUDENTS)

May 29, 2019November 23, 2020 Chris 10000 Views 19 Comments

BGP Labeled-Unicast is the key to making Interprovider Option C work. So, before we learn how to use Option C to extend an MPLS VPn between two ISPs, let’s learn all about this interesting address family. And if you like, we can even hold hands while we learn!

INTERPROVIDER OPTION B, ON JUNIPER JUNOS ROUTERS (INCLUDES FULL TOPOLOGY CONFIG!) (JNCIP-SP, JNCIE-SP)

May 19, 2019July 6, 2020 Chris 4507 Views 4 Comments

Let’s learn how to stretch an MPLS VPN between ISPs using a thing called “Option B”. It involves a little bit of trust between the ISPs – but as we’ll see, it greatly reduces the complexity in configuration!

JUNOS ROUTING POLICY, BGP COMMUNITIES, AND MPLS VPNs

January 4, 2019January 4, 2019 Chris 11889 Views 0 Comments

I fixed a ticket recently that I wanted to share with you, because it hits on three big topics at once: BGP communities, MPLS VPNs, and Junos routing policy. In this first of two posts, we’re going to learn about the theory. Click here to read all about BGP communities!

MOVING LSPs BETWEEN INET.3 and INET.0 ON A JUNIPER ROUTER

October 8, 2018October 20, 2018 Chris 7776 Views 4 Comments

This is a post about the different ways, and reasons why, we might move prefixes between the inet.3 and inet.0 tables on a Juniper router. You know: like George Clooney does in his spare time. Probably. Don’t look that up.

JUNOS ROUTERS: WHAT DOES THE INET.3 TABLE ACTUALLY DO?

October 8, 2018November 1, 2020 Chris 11561 Views 15 Comments

In this first of a two-part post, I’m going to take you on a magical journey. And by “take you on a magical journey” I mean “teach you what the inet.3 table does on a Juniper router.” Which is basically the same thing as a magical journey, right?

Hi!

I’m Chris, a network engineer, Juniper Ambassador and JNCIE-SP #2981. I’ve contributed towards a few books for Juniper in my time, and I have a few vendor certifications too, from Juniper, Cisco, Palo Alto and F5. But don’t mistake it for me actually knowing anything: I just do exams because I like a good pub quiz.

This is a blog of random knowledge I’ve acquired while studying for those sweet sweet network engineering certifications. There’s a big focus on Juniper in this blog, but sometimes I do other vendors too.

As I learn cool new stuff, I try to write it up with plenty of jokes, and a generous dollop of silliness, so that you’ll have as much fun learning about networking as I do.
