Description Pablo Alonso Rodriguez 2019-07-22 11:17:05 UTC
Description of problem:

When user setups egressCIDRs 

Version-Release number of selected component (if applicable):

openshift v3.11.98

How reproducible:

Only on user environment but consistently. Not reproducible on test cluster.

Steps to Reproduce:
1. Setup egress IPs on some hostsubnets
2. Setup a netnamespace using one of them

Actual results:

IP is not added at network interface and some errors are displayed on logs. I need to add the IP manually (ip addr add $IPCIDR dev $INTERFACE) for it to work.

Expected results:

IP to be added automatically when there are both a hostsubnet and a netnamespace specifying it.

Additional info:

Interface is a team interface, but I have been doing tests in my lab and it is not reproducible there.
