Trying to get an idea of the "official" MikroTik answer here. As far as I can tell, unless you're redistributing connected, rip, bgp, static, etc , it's not possible to filter routes for LSA types that aren't external
In ROSv6 the official answer to filtering routes outbound for an LSDB within the same area was "not possible" unless they are external routes.
In ROSv7 i've come across a few posts that claim it's possible but I've not been able to replicate the same result using the config referenced.
Note: I'm mainly trying to confirm whether or not /routing/ospf/out-filter-chain can filter routes to other OSPF neighbors when redistribution isn't being used. This is for lab testing and as such, i'm not trying to find a "workaround"
