Fixed In:
12.0.0, 11.6.0 HF5, 11.5.4, 11.4.1 HF9

Opened: Aug 20, 2014

Severity: 3-Major


When multiple route domains and multiple routing protocols per route domain are repeatedly created and deleted, the tmrouted crashes and restarts.


The routing information is lost and the tables need to be built again. This might cause packet loss.


multiple route domains with multiple routing protocols per each route domain are created and deleted repeatedly in a short time intervals.



Fix Information

Repeated creation and deletion of route domains and routing protocols led to a race condition between the start timer of the routing protocols and inconsistent memory state of the deleted routing protocols. This fix resolves the race condition.
