Intermittent connectivity observed with IPsec configured on Openshift
Issue
- After enabling IPsec at the host level on Openshift nodes, there are intermittent connectivity issues between containers.
- The connectivity is established again only after a network action is initiated manually, like ping to the host.
- This happens with Opportunistic Encryption as well as non-Opportunistic configuration.
Environment
- Openshift Container Platform 3.11.200
- libreswan-3.25-4.8.el7_6
