Public bug reported:
If I am trying to get rid of IPv4 and IPv6 addresses on a particular interface
using Netplan, if I use NetworkManager as the renderer, it does not follow the
last of these three Netplan documentation examples:
Example to enable only IPv4 link-local: link-local: [ ipv4 ]
Example to enable all link-local addresses: link-local: [ ipv4, ipv6 ]
Example to disable all link-local addresses: link-local: [ ]
/etc/netplan/01-network-manager-all.yaml
network:
version: 2
renderer: NetworkManager
ethernets:
lan:
match:
macaddress: a8:20:XX:XX:9f:da
dhcp6: true
addresses:
- 192.168.1.3/24
routes:
- to: default
via: 192.168.1.1
metric: 100
nameservers:
addresses: [192.168.1.1]
search: []
set-name: lan
softether:
match:
macaddress: 40:6c:XX:XX:4a:93
optional: true
link-local: []
set-name: softether
Followed by `netplan generate` and `netplan apply`, results of `ip a` for the
softether interface...
2: softether: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP
group default qlen 1000

However, if the renderer is changed to networkd...
network:
version: 2
renderer: networkd
ethernets:
lan:
match:
macaddress: a8:20:XX:XX:9f:da
dhcp6: true
addresses:
- 192.168.1.3/24
routes:
- to: default
via: 192.168.1.1
metric: 100
nameservers:
addresses: [192.168.1.1]
search: []
set-name: lan
softether:
match:
macaddress: 40:6c:XX:XX:4a:93
optional: true
link-local: []
set-name: softether
Then `netplan generate` and `netplan apply`, results of `ip a` for the
softether interface...
2: softether: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP
group default qlen 1000
link/ether 40:6c:XX:XX:4a:93 brd ff:ff:ff:ff:ff:ff
altname enp9s0
To recap, using NetworkManager as the renderer for Netplan fails to
eliminate IPv4 and IPv6 addresses when setting link-local: [].
