Description Victor Voronkov 2020-12-29 16:02:53 UTC

Version:

4.7.0-fc.0

Platform:

baremetal IPI

What happened?

OVN create a bridge over the interface that was configured by the script and keep dhcp:

[core@master-0-0 ~]$ nmcli con show br-ex | grep method
ipv4.method:                            auto
ipv6.method:                            auto

What did you expect to happen?

That the external interface will have static IP configured and will not request DHCP lease anymore, when infinite lease was configured

How to reproduce it (as minimally and precisely as possible)?

Deploy cluster with infinite lease and OVN

Anything else we need to know?

In case cluster is deployed with OVS (OpenshiftSDN) static IP is configured as expected:

[core@master-0-0 ~]$ nmcli con show
NAME                 UUID                                  TYPE      DEVICE 
inf-lease-to-static  44c87dc3-4dea-4a00-9ad2-dba55b509b20  ethernet  enp5s0 
[core@master-0-0 ~]$ nmcli con show inf-lease-to-static | grep method
ipv4.method:                            manual
ipv6.method:                            auto

Comment 1 Ben Nemec 2021-01-04 14:22:30 UTC

br-ex isn't the nmcli interface that is configured by the script. There's a different one named ovs-if-br-ex that should have the manual configuration. Can you check if that interface was correctly configured?

Verified on 4.7.0-0.nightly-2021-01-09-021054
with dual stack

[core@master-0-0 ~]$ nmcli con show ovs-if-br-ex | grep method
ipv4.method:                            manual
ipv6.method:                            manual
