In this post we show how to configure RSVP in Junos – and then we roll up our sleeves to look at some packet captures of the PATH and RESV messages on the wire. There’s some mighty fine learning in this post!
I recently received an email from someone asking if I knew a good complete beginners guide to MPLS. Their mail inspired me, so I wrote one for them – and now, I’m sharing it with you! If you’ve always wanted to know what MPLS is, click here to fulfill your deepest dreams.
Pseudowires are easy on the surface – but dig a bit deeper, and there’s some interesting complexity. Click here to learn the details about BGP-signalled L2VPNs!
Container LSPs let us automatically create MPLS LSPs when we need them, and tear them down when we don’t. We can automate load-balancing, and keep the state in our network to a minimum. It’s really nice! Click here to read all about them, in the third and final part of this series on MPLS bandwidth, and automating our network to get the most out of it.
Setting RSVP bandwidth reservations automatically is very prone to error. Luckily, there’s a better way: we can automate the whole thing using the Junos auto-bandwidth command. Let’s take a look at some cool new Juniper config!
RSVP lets us create LSPs that reserve bandwidth in advance. And that’s exactly what this three-part blog post series is all about! In this first post we’re going to learn how we combine bandwidth and priorities to get the most out of the bandwidth in our network. Click here for good times!
BFD is a protocol that gives all your other protocols sub-second failure detection times. Very useful! This blog post uses Junos config, but the explanation is multi-vendor. Give it a read!
The independent-domain command is a little-known but big-useful command. Let’s see how we can use it in Junos to tunnel localpref info from one VPN customer site to another!
In this post we use both Cisco IOS and Juniper Junos config to see the difference between route-distinguishers and route-targets in MPLS VPNs. Why do we need both of them? Click here to find out!
