Auto Zoning Issue : Cisco ASA Migration with Dynamic Routing

Trying to migrate an ASA which uses BGP and OSPF. Since the dynamic routing tables are not part of the ASA configuration, destination auto zoning does not work as expected. I thought of adding those dynamic routes as static routs to the ASA config (but there are too many) for the destination auto zoning to work. Is there any other work flow available for ASA with large dynamic routing tables?

@Kushantha , Expedition does not currently support dynamic routing migration, so I would suggest you filter the security policies based on source or destination with a filter based on subnet, For example, if your subnet is 10.0.0.0/24 and you can filter policy basd on the subnet like below screenshot:

then highlight the security rules you want to apply zone and right-click on "Bulk Changes" -> Zones, to apply zone on source or destinations.

Thanks a lot. This is what I have been doing (update the zone based on subnet/IP).

I hope future iteration of Expedition will support us to import Cisco ASA routing tables separately, as it supports Check Point migration today.
