Hi
i just tested this , it did not drop my opsf neighbors or have any effect on the LSDB , see below also for mac answer it will purge be careful

mac-address-table synchronize
mac-address-table aging-time 0 routed-mac
Note: “mac-address-table synchronize command purges the routed MAC entires. In order to
avoid this, disable the routed MAC purging with the mac-address-table aging-time 0
routed-mac global configuration command.”
The mac-address-table aging-time 0 routed-mac in the SXH code train has been deprecated,
So as we move to SXH this command is no longer needed when using the synchronized
functions.
