Route filtering

For networks with Route Learning enabled, Citrix SD-WAN provides more control over which SD-WAN routes are advertised to routing neighbors rather and which routes are received from routing neighbors, rather than advertising and accepting all or no routes.

Export Filters are used to include or exclude routes for advertisement using OSPF and BGP protocols based on specific match criteria. Export filter rules are the rules that have to be meet when advertising SD-WAN routes over dynamic routing protocols. All the routes are advertised to peers by default.
Import Filters are used to accept or not accept routes which are received using OSPF and BGP neighbors based on specific match criteria. Import filter rules are the rules that have to be meet before importing dynamic routes into the SD-WAN route database. No routes are imported by default.

Route filtering is implemented on LAN routes and Virtual Path routes in an SD-WAN network (Data Center/Branch) and is advertised to a non-SD-WAN network through using BGP and OSPF.

You can configure up to 512 Export Filters and 512 Import Filters. This is the overall limit, not per routing domain limit.
