BGP Labs: Protect EBGP Sessions
I published another BGP labs exercise a few days ago. You can use it to practice EBGP session protection, including Generalized TTL Security Mechanism (GTSM) and TCP MD5 checksums1.
I would strongly recommend to run BGP labs with netlab, but if you like extra work, feel free to use any system you like including physical hardware.

I would love to add TCP-AO to the mix, but it’s not yet supported by the Linux kernel, and so cannot be used in Cumulus Linux or FRR containers. ↩︎
