1.3.13. Networking

You can now use enhanced MetalLB Operator reporting features to view real-time operational data for IP address allocation and Border Gateway Protocol (BGP) connectivity. Previously, viewing this information required manual log inspection across multiple controllers. With this release, you can monitor your network health and resolve connectivity issues directly through the following custom resources:

OpenShift Container Platform 4.20 introduced unassisted holdover for boundary clocks and time synchronous clocks as a Technology Preview feature. This feature is now Generally Available (GA).

For more information, see Applying unassisted holdover for boundary clocks and time slave clocks.

With this release, the PTP Operator introduces an active GNSS-to-NTP failover configuration to ensure time synchronization continuity in environments requiring extremely high time accuracy.

When the primary Global Navigation Satellite System (GNSS) signal is lost or compromised, for example because of satellite jamming, the system automatically fails over to Network Time Protocol (NTP) to maintain time accuracy. When the GNSS signal is restored, the system automatically recovers back to using GNSS as the primary time source.

This feature is particularly important in telco environments that require high precision time synchronization with built-in redundancy. To enable GNSS to NTP failover, you configure the PtpConfig resource with the ntpfailover plugin enabled and configure both chronyd and ts2phc settings.

For more information, see Configuring GNSS failover to NTP for time synchronization continuity.
