Conditions
The root cause of the problem is that OSPF sends a route delete whenever it adds a route for the first time and it tries to delete the route from the RIB by table-map configuration. Moreover, the log is seen for the routes which are already present in the RIB.
Workaround
per the communication with URIB team, this syslog has no functional effect, so setting the logging level to 4 will prevent the priming of these messages into the sys log.
6.2.2, 6.2.4, 6.2.6, 7.0 are affected by this this. In 6.2.2, 6.2.4, 6.2.6 and 7.0, only OSPFv2 is susceptible to this bug. We tested the same scenario for OSPFv3 but we did not see the issue.
6.2.6a, 6.2.8 and 7.1 have the fix for this problem. In these releases the aforementioned trigger in Conditions: does not lead to URIB printing the syslog messages.
