The topic of this post is Layer 3 VPN (L3VPN or VPRN as we call it in SROS) configuration, and I decided to kill two birds with one stone by inviting Juniper vMX to our cozy SROS environment.

The BGP/MPLS VPN (RFC 4364) configuration will undergo the following milestones:

PE-PE relationship configuration with VPN IPv4 address family introduction PE-CE routing configuration with both BGP and OSPF as routing protocols Export policy configuration for advertising VPN routes on PE routers AS override configuration and many more

We’ll wrap it up with the Control Plane/Data Plane evaluation diagrams which help a lot with understanding the whole BGP VPN mechanics. Take your seats, and buckle up!
