This did solve it. I did not search thoroughly enough it seems.

this issues was resolved on https://vyos.dev/T5127. It happens when FRR tries to calculate the auto-rd per vrf . it can be solved by using router-id on each vrf or interface dummy in the VRFs ,

I checked 6 routers, 2 showed the issue. No idea what the impact is. All of them running 1.3.2.

Maybe this [a-zA-Z_](?:[a-zA-Z0-9_\-\.]{0,}[a-zA-Z0-9_\-])?

I have the correct host-name after reboot

@zsdc I built the image now, and it works as expected. The issue looks resolved. Thank you.

@dutty can you try to build an image again and check now?

Yes, T4737 looks the same.

Could you show a version of FRR?

show version all | match frr

Added extension and example for test_vif_8021q_mtu_limits.

One fix added; I'm looking at an extension for the case of test_vif_8021q_mtu_limits, as mentioned in the comment in base_interfaces_test.py.

Let me cherry-pick these and commit all at one

I discovered that conntrack are enabled by default in two files:

How far are we in the testing of this important feature ?

All of the modem specific settings appear to be done through the web GUI of the modem.

I could have sworn it took quite a while for the wlb.out to be populated when testing earlier on. However as I´ve built out the config a bit more I am now only able to reproduce it a few seconds after reboot - so your theory holds. Let's close out the bug report for now and I´ll reopen if something changes down the line.

Virtual-ethernet interfaces veth implemented in T4825
For veth in "netns" it should be a separate task.

I can't reproduce it VyOS 1.4-rolling-202305250317

Thanks Viacheslav , for this clarification . Veths /Netns are strong powerful , using this technology we can use to join different hypervisor or bridge technology . leave some example namespaces /veth / bridging.

Sorry to write on a closed task, but without specifying a vrf (or some kind of identifier for that matter), how will the DHCP server decide which shared network to use since they have identical subnets configured?
