Inter-AS L3VPN Option B

Packet Corner

In this post, we are going to go through the implementation and verification steps of Inter-AS Option B (defined in RFC4364 ). Please refer to previous post Inter-AS Options to for the definitions, and differences of the three.

In option B implementation, ASBRs themselves are PE routers. They learn VPN-IPv4 routes from other PEs from the same AS via MP-iBGP (either directly or via Route Reflectors). The ASBR from one AS then have an eBGP session(s) with other AS ASBR to redistribute the VPN-IPv4 routes to the other AS. The later ASBR then redistributes those VPN-IPv4 labeled routes to the rest of the PEs belonging to that AS.



In this topology, we use Cisco IOS routers (R1 – R3) in AS100, as well as Juniper routers (R4 – R6) in AS200, just for demonstration of configuration and verification on both platforms. Typically for connectivity beween ASes, one eBGP…

Danny Insight

By Daniel Chokoe


Most businesses exist because they want to make money, income can be made through the sale of services or products.

Sales people excel in making even the simplest feature sound exciting, they have the ability to convince you that you need their product.

I have been fulfilling a role as an Account Manager on S2B program at Microsoft, although I am a qalified IT specialist I…
