netlab release 1.9.3 brings these new features:

• Multi-chassis Link Aggregation (MLAG) on Arista EOS, Aruba CX, Cumulus NVUE, and Dell OS10
• VRF and VLAN groups
• Additional OSPF interface parameters (hello and dead timers, cleartext passwords, and DR priority) implemented on Arista EOS, Aruba CX, Cisco IOS/IOS-XE, Cisco Nexus OS, Cumulus Linux, Dell OS10, and FRRouting
• Static routes with direct or indirect next hops implemented on Arista EOS, Cisco IOS/IOS-XE, FRRouting, and Linux
• Node cloning plugin for users who want to build detailed digital twins of their networks.
• Consistent selection of default address pools based on the number of nodes attached to a link (this could change addressing in multi-provider topologies)
• Support for vjunos-router and Cisco NSO tool.

Other new features include:

• FRR VM uses Debian/Bookworm
• Bird container uses Ubuntu 24.04
• Containerlab stub links use dummy interfaces, removing the need for extra Linux bridges
• FRRouting supports RFC 8950-style IPv4 next hops over regular IPv6 EBGP sessions
• You can use --feature flag with the netlab show modules command to display support for a single optional feature
• STP is disabled on libvirt-created bridges to avoid interference with the STP Configuration Module
• Per-node device features allow you to tweak which features individual lab nodes support
• Most OSPF parameters can be set on the topology- or node level, including the default passive state
• netlab validate prints time spent in every successful validation test.
