This time I will cover in details basic Layer 3 VPN
(L3VPN or VPRN) configuration, and I decided to kill two birds with one stone by inviting Juniper vMX (read here
on how to add vMX to Unetlab) to our cozy Alcatel-Lucent environment.
In this post we will configure BGP/MPLS VPN [RFC 4364] including:
- PE-PE relationship configuration with VPN IPv4 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
As a bonus track I will share with you Control Plane and Data Plane evaluation diagrams which help a lot for understanding the whole BGP VPN picture. Take your seats, there is no flying from VPNs!
Juniper offers its brilliant MX routers for virtual environments – namely vMX. And we cant name ourselves engineers if we wouldn’t try to run one in the Unetlab. Running vMX in the unetlab is a simple task, yet I see many complaints about vMX not working. With this being said I invite you to a journey called “running vMX in Unetlab. Painless edition”.
