This article describes that Route Mapping has different use cases on it is preferred to be: allow or deny specific routes advertised through dynamic routing protocols such as BGP and OSPF.
Example of route-map use cases with BGP can be found at the following link:
Starting from FortiOS 7.2.1 due to a known issue that was discovered in the commands: 'route-map-out' and 'route-map-out-preferred' where vpn4 prefixes were not advertised correctly by the 'route-map-out-preferred', new commands were introduced to enhance the functionality and resolve such issue:
config router bpg
config neighbor
edit <neighbor name>
set route-map-out-vpnv4 <--
set route-map-out-vpnv4-prefered <--
………
Sometimes the new commands may not perform properly as these were custom commands introduced for the first time on a special build for specific cases reported to the support team. The solution is to revert to using 'route-map-out' and 'route-map-out-prefered'.
