netlab release 1.6.3 added numerous BGP nerd knobs:

• You can create EBGP multihop sessions in the global routing table when using Arista EOS, Cisco IOSv, Cisco IOS-XE, FRR and Cumulus Linux 4.x.
• ebgp.utils plugin supports TCP-AO, configurable BGP timers, and Generic TTL Security Mechanism (TTL session protection)
• BGP neighbor reports hide irrelevant columns.

We also:

• Added OSPF reports in Markdown, HTML and text format
• Implemented BFD on Cumulus Linux
• Added collect configuration action for FRR and changed default FRR release to 9.0.1
• Implemented gRPC test topology for users of Nokia SR Linux and SR OS devices

Finally, a few features for the advanced users:

• If you’re relying on bleeding-edge netlab features you can specify minimum netlab version in lab topology
• The new ‘disable’ link attribute allows you to remove individual links from lab topology during the troubleshooting process.
• If you’re writing plugins, you might like the ability to load plugin-related defaults (example: additional attributes) from a YAML file instead of defining them in Python code.
• If you don’t like the way netlab configures network devices, use your own configuration templates that can be loaded from system- or user directory
