Pseudo-ethernet Interfaces Not Loaded on Boot
Closed, ResolvedPublicBUG

Description

It appears that on the most recent rolling releases, pseudo-ethernet interfaces are not loaded on boot. I'm not sure if it's related to the fact that the source-interface is a bond or not, but it's worth mentioning.
Here's before reboot:

vyos@cr01b-vyos# show interfaces pseudo-ethernet
 pseudo-ethernet peth0 {
     address 192.168.100.4/24
     description "MB8600 Management"
     source-interface bond1
 }

Just tested this using 1.3-rolling-202004201924 and it still happens, so that doesn't appear to have worked.

Next rolling will have the definitive fix :)
