Last Modified: May 29, 2024

Affected Product(s):
BIG-IP TMOS(all modules)

Known Affected Versions:,,,,,,, 14.1.3, 15.0.0, 15.0.1,,,,, 15.1.0,,,,,, 15.1.1, 16.0.0,, 16.0.1

Fixed In:
16.1.0,, 15.1.2,,

Opened: May 19, 2020

Severity: 2-Critical


After SPF/IA calculation gets suspended, it might enter a state where it never fires again.


OSPF routes are visible in the OSPF database, but not installed in the routing table.


SPF/IA calculation gets suspended; This occurs for various reasons; BIG-IP end users have no influence on it occurring.


Restart the routing daemons: # bigstart restart tmrouted Running this command allows you to recover from this situation, but does not prevent the event from reoccurring. If due to a topology, SPF/IA calculation suspension occurs again after a restart, this workaround essentially has no effect.
