Title:
unconfigured interfaces part of a 802.3ad bond getting DHCP IP & being
set as default route
Status in netplan:
Expired
Status in netplan.io package in Ubuntu:
Expired
Bug description:
Hi,
I have the following configuration:
network:
version: 2
renderer: networkd
ethernets:
enp1s0:
optional: true
enp2s0:
optional: true
enp3s0:
optional: true
enp4s0:
optional: true
bridges:
br0:
interfaces: [enp2s0, enp4s0]
addresses: [192.168.1.1/24]
bonds:
bond0:
interfaces: [enp1s0, enp3s0]
dhcp4: yes
dhcp6: yes
parameters:
mode: 802.3ad
mii-monitor-interval: 100ms
lacp-rate: fast
The issue I'm having is that after doing a "netplan apply" or
rebooting my machine the enp1s0 and enp2s0 interfaces that are part of
bond0 are getting assigned IPs:

Even more problematic is the fact that those two interfaces are also
being set as the default route ahead of bond0:

This really doesn't make sense to me since those should be
"unconfigured" interfaces. I really want those interfaces to not show
in my default routing table at all. Thanks for the help.
