BGP Labs: Bidirectional Route Redistribution
In the next BGP labs exercise you’ll build the customer part of an MPLS/VPN solution. You’ll use bidirectional OSPF-to-BGP route redistribution to connect two sites running OSPF over a Service Provider MPLS backbone.
I would strongly recommend to run labs with netlab, but if you like extra work, feel free to use any system you like including physical hardware.
To make it a bit more realistic scenario; what would happen if customer wants to use same AS on their all branches. So we had to play around to disable AS loop mechanism.
Typically on PE router you would configure AS Override Feature and Site of Origin (SoO) BGP extended community for loop prevention towards CE router.

Thanks for the idea. I will definitely add that scenario when creating MPLS/VPN labs.

That's planned. See https://ipspace.github.io/bgplab/3-upcoming/ for details
