If BIG-IP receives an OSPF LSA with an external tag set and the ensuing route is redistributed into another protocol, including an OSPF process, updates to the tag may not be preserved.
Routing policy may not be executed correctly leading to misrouted or discarded traffic.
-- Redistributing routes from OSPF process to another protocol or process. -- OSPF LSAs with external route tag != 0. -- External route tag changes to 0.
Clearing the affected route resolves the issue. This might require clearing the OSPF process. To do so, follow this process: In imish, run the following command: clear ip ospf This interrupts routing that relies on OSPF until the network reconverges.
OSPF external tag updates are correctly propagated through redistribution.
