Static route gets ignored

Question

Hi. 
 I use a XG with 19.5.1 MR-1-Build278 Firmware.I have a strange behavior. Today, we can't ping our servers located at a "site to site vpn" branch office. 
 By now, all I can tell is, that the specific static route gets ignored. I see it on the web interface of the XG but when doing a route -n on the command line of the XG, there is no such route. Removing it and adding it through the Web interface does not help. 
 As you can see, the newly created route to 10.1.22.0 is added, but the route to 10.1.19.0 is missing. Even when newly created. When I create a route to a specific host (let's say 10.1.19.65, it gets added.

What is going on here? Any help is welcome. 
 Best regards, 
 Christian

Hi Sophos User3052 : Your case has been updated by the GES team and it is confirmed that the issue is related to NC-114292. Fix for this issue id is taken in the SFOS v19.5.3 MR-3. 
 For the workaround, you can restart the Zebra service after migrating the device to v19.5.1 MR-1.To restart the Zebra service, please use the below command in the advanced shell. 
 "service zebra:restart -ds nosync"

Hi All, Please find the below general information if anyone is referring to this thread and would like to confirm whether their issue is related to NC-114292 or not.

If the zebra.log contains a "netlink-dp" msg with an error like below then it confirms the issue is related to NC-114292.

"netlink-dp` (NS 0) error: Numerical result out of range, type=RTM_NEWROUTE(XX), seq=YYYY, pid=ZZZZZZZZZ"

If the above error is not present then the issue may require a separate investigation with a support ticket to review the logs and validate it further.

Note: failed to install for table: 254" might be present due to interface is down at the time of static config apply.
