CCIE SP - Inter-AS MPLS VPN - All Inter-AS Options - Initial + Full Configs

Inter-AS MPLS VPN enables secure and scalable VPN connectivity between different Autonomous Systems (ASes), allowing service providers to extend MPLS-based VPNs beyond a single AS. It supports multiple deployment models—Option A (back-to-back VRFs), Option B (MP-eBGP label exchange), Option C (end-to-end label switching with BGP Labeled Unicast), and Option D (enhanced Option C with SR or RSVP-TE)—each offering trade-offs in complexity, scalability, and operational overhead.

These solutions help large-scale ISPs and enterprises achieve seamless, multi-AS connectivity while maintaining traffic separation and QoS policies.

Mastering Inter-AS MPLS VPNs is essential for network engineers working on global-scale MPLS architectures and cross-provider VPN services.

The default username and password for images used in this course is as follows, however you will hear new passwords during the course if the instructor changes the credentials: 

** For Cisco XRv you are asked for a username and password in the loading process. You can add any username and password other than admin, root, sysadmin and other reserved usernames. Go with something like Alex/cisco e.g.

Then when completely loaded, you can use cisco/cisco or admin/admin.

***For XRv9K Full image you are asked for a username and password in the loading process. You then login using the username and password that you set.
