Matching on permitted values is not allowed about synet-plus HOT 2 CLOSED

Well, non-permitted announcements are those which are dropped at a router before in the path. So matching on something that the router wont see at all doesn't make sense.

Note, the permitted field is not part of the BGP announcement, it's just a marker that NetComplete uses to mark dropped and non-dropped announcements.

Cisco, as NetComplete, can drop all announcements received.
In Cisco it would be something like:

!
route-map Policy deny 10
!

Note, this route map has no match and no action but it has deny keyword. So it will drop all the announcements that passes through. Additionally, you can define a match to specify that you want to drop a subset of the announcements.

In NetComplete it's very similar semantics

RouteMapLine(matches=None, actions=None, access=Access.deny, lineno=10)

Thanks, this clarifies it. I imagine you can remove MatchPermitted then from the code-base.
