Changes in Release 1.6¶

New Functionality ¶

Release 1.6.2 ¶

Support for ArubaOS-CX with containerlab
Display a subset of available reports in netlab show reports command
Display warnings in reports relying on ipaddr Ansible filter
Add IPv6 prefixes and neighbors to BGP reports
Add IPv6 column to text addressing report
Make some columns optional in BGP reports to reduce the report width
Implement inter-VRF route leaking for Cumulus/FRR

Release 1.6.1 ¶

netlab report can generate Markdown markup (ideal for augmenting documentation written in Markdown)
BGP AS number and BGP neighbor reports (text, Markdown, HTML)
Make user/system default locations configurable

Internal changes:

netsim no longer uses netsim.common module. This change might impact existing plugins.

Release 1.6.0 ¶

New commands:

netlab report generates built-in or user-defined text- or HTML reports based on transformed lab topology.
netlab graph command generates topology graph descriptions in GraphViz or D2 format
netlab inspect command displays data structures in transformed lab topology
Improved netlab show command displays information as a table, raw text, or YAML

New reports:

The reports you can create with the netlab report command include:

Node, interface and link addressing reports
Lab wiring summary
Device management IP addresses, usernames, and passwords

Explore netlab internals

The netlab show command can display:

Configuration modules and optional features supported by individual modules
Configuration modules and features supported by individual devices
Virtualization providers and their status
Output modules that can be used with the netlab create command
System reports you can use with netlab report command

External connectivity:

Connect containers to outside world through macvlan interfaces (requires containerlab release 0.43.0)
Host-to-VM port forwarding in libvirt environment
Mapping of container management ports to host ports

Other new features:

Improved FRR VXLAN data plane configuration
OSPF strict BFD support (RFC 9355)
Nokia SR OS OSPF P2MP support
Add mgmt._permanent option to make vagrant-libvirt management network persistent (fixes #855)

Documentation improvements:

Document Linux loopback interface usage
Document assignment of management IP addresses in libvirt and containerlab environments
Rewrite documentation for external provider and multi-provider topologies

Internal changes:

Use device features instead of module supported_on lists to specify modules supported by individual devices
Device settings inheritance should make it easier to add similar devices. It has been implemented for most device types, including a new Junos meta-device (the parent for vSRX, vMX and vPTX devices).

Breaking changes:

get_from_box function has been removed

netlab code stopped using netsim.common module. That module should no longer be used, but is still included in the package in case some plugins still use it. We’ll remove the module in 1.7/2.0 release.

Release 1.6.0 ¶

get_from_box function has been removed. The function might be used by early plugins which will break when ran with netlab release 1.6.0. Update your plugins to use Box get method which supports hierarchical names since version 7.0 (more details)

Bug Fixes ¶

Bug Fixes in Release 1.6.2 ¶

Bug Fixes in Release 1.6.1 ¶

Python package manifest (MANIFEST.in) did not include show-usage.txt (the help file for netlab show command)
Collect Cumulus Linux interface configuration with ifquery
ifquery has to be executed as root on Cumulus Linux

Bug Fixes in Release 1.6.0 ¶

Allow ‘mgmt’ attributes in node data
Change pinned containerlab version to the one supporting macvlan endpoints
Create system-wide virsh networks during ‘netlab up’
Fix a typo in a BGP attribute type
Update SRv6 module to use new dictionary-based attribute definition
