Introduction In the last post, Simple Cisco MPLS Core w/ L3VPN (Part 1), we created a simple MPLS core using Cisco CSR1000v routers which was similar to the Simple Juniper MPLS Core w/ L3VPN (Part 1).  Now that the basics are in working order (remember, the simple core does not do anything special such as…

Introduction I decided to create a few follow-up posts on the Multiprotocol Label Switching (MPLS) topic but instead of focusing on Juniper configurations, I am going to re-create the topology using Cisco configurations.  In all honesty, the basics are the same in how the topology works with regards to using an internal routing protocol (again,…

Introduction If you haven’t already, please go to the first post Simple Juniper MPLS Core w/ L3VPN (Part 1) as that sets up the topology, routing, and label distribution that we need to continue setting up our customer edge devices.  For this post, we need to do a few things to successfully route traffic from…

Introduction Setting up a simple MPLS core using virtual SRX’s is simple and only limited by the hardware which you run the virtual machines (other limitations exist for MPLS using vSRX’s including not being able to run Layer 2 services such as VPLS and L2circuts).  Using these virtual machines, we can create a complete MPLS…
