It’s been a while since the last netlab release. Most of that time was spent refactoring stuff that you don’t care about, but you might like these features:

• You can run automated lab validation tests with the netlab validate command. I will explain how I use that in BGP labs in a few days.
• If you want to build large leaf-and-spine topologies, you’ll love the fabric plugin.
• The bgp.domain plugin allows you to create topologies with multiple sites using the same BGP AS number.
• The bgp.policy plugin got AS-path prepending.
• bgp.originate plugin can be used to originate BGP IPv4 and IPv6 prefixes.

As always, we also improved the platform support:

• The --show option of the netlab connect command implements a consistent cross-device way of executing show commands. You might find it handy if you hate guessing whether to use vtysh or sudo vtysh with Cumulus and FRR containers.
• vptx device supports the vJunosEvolved release 23.2R1-S1.8. Older vJunos Evolved releases no longer work
• You can use bgp.session plugin to configure BFD, BGP timers, and passive BGP for Junos devices (vMX, vSRX, vPTX)
• bgp.session plugin got AS-path manipulation, default route origination, TTL security, passive BGP peers, MD5 passwords, and BGP timers on Cisco NexusOS
• MPLS LDP now works on Nokia SR Linux
• Aruba AOS-CX supports L3VNI (you’ll need release 10.13 to make it work)
• Default FRR release is 9.1.0
