Bug ID 1252377: VXLAN-GPE and GENEVE are disabled by default when software is upgraded from F5OS-A 1.3.0 build to F5OS-A 1.4.0

Last Modified: Feb 08, 2024

Affected Product(s):
F5OS Install/Upgrade, Velos(all modules)

Fixed In:
F5OS-A 1.7.0, F5OS-A 1.4.0

Opened: Feb 27, 2023

Severity: 2-Critical

Symptoms

When r10000 or r5000 Series hardware is running with F5OS-A 1.3.0, the default settings for VXLAN-GPE and GENEVE are enabled, and hardware disaggregation support for these tunnel protocols is enabled without any explicit configuration. If the software is upgraded from F5OS-A 1.3.0 to F5OS-A 1.4.0, these protocols will be disabled, and hardware disaggregation is disabled. It is required to enable these two protocols explicitly in the configuration to enabled them in the hardware.

Impact

Hardware disaggregation support for VXLAN-GPE and GENEVE will be disabled if software is upgraded from F5OS-A 1.3.0 to F5OS-A 1.4.0 or later when these two tunnels are using default configuration to enable them.

Conditions

If VXLAN-GPE and GENEVE tunnels are used in the deployment with F5OS-A 1.3.0 software version without any explicit enabled configuration for these two tunnels, and software upgraded to F5OS-A 1.4.0 or later.

Workaround

Use explicit tunnel settings to enable VXLAN-GPE and GENEVE in F5OS-A 1.3.0, or enable these two protocols explicitly after software upgrade from F5OS-A 1.3.0.

Fix Information

VXLAN-GPE and GENEVE are disabled in default global configuration and advised to use explicit tunnel configuration settings to enable hardware disaggregation support.
