XG Firewall 18.0 GA-Build379 routing table inconsistent after backup restore

Samuel Heinrich

fyi...

we've noticed an issue after restoring a backup to fresh re-imaged (18.0 GA-Build379) XG330 appliances.

after restoring the backup, some branches were not reachable, because of missing static routes in the routing table, although they were clearly visible in the GUI. 

 

We were able to fix the issue by editing each missing route in the GUI and save it. To force it we changed metric from 0 to 1

 

 

unfortunately, this is not the first time we've experienced such problems that "GUI" does not reflect the "running-config"...

    There are logs which try to import those settings into the kernel / routing stacks. 

    https://community.sophos.com/kb/en-us/132211

     

    Try to find any indication by looking into all Logs.

    Simple: grep "10.9.104.0" /log/*.log | less 

    Then try to find the first entry and note the time / logfile.

    Go into the log file and browse to the time, try to find any related information to this issue. It seems like the kernel tried to import this route, but failed.

    Hi Toni

    Thank you also for your fast response.

    great hint, looks like there is a logfile "zebra.log" for static routing, but it is not located in /log/ 

     

    XG330_WP02_SFOS 18.0.0 GA-Build379.HF043020# find /* | grep zebra.log
    /var/tslog/zebra.log

    unfortunately, there is no indication for unsuccessful route installation:

     

    XG330_WP02_SFOS 18.0.0 GA-Build379.HF043020# cat /var/tslog/zebra.log

    -> I count 23 routes, which is equal with the number of routes in the GUI. 

     

    no other matched in logfiles from yesterday, after backup restore.
