Opened: May 19, 2020
Severity: 2-Critical

Symptoms

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

Impact

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

Conditions

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

Workaround

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.

Fix Information

None
