- [Description]
+ [Impact]
When attaching multiple IPs on secondary interface the routing policy rules
do not
apply for all IPs.
The rules that are applied after restarting networkd are random.
The issue has been reported and addressed upstream.
[Test Case]
Attach multiple IPs to secondary interface, config file:
- $ cat /etc/systemd/network/ens8.network
+ $ cat /etc/systemd/network/ens8.network
[Match]
Name=ens8

The behaviour is random
+
+
+ [Regression Potential]
+
+ May impact the systemd-networkd service functionality.

[Other]
Affects Disco and Bionic (probably Cosmic as well, but haven't tested it
yet).
