I have a setup where we connect a OSPF area with a edge router, this edge

My router is running FreeBSD 11.1 with openbgpd

openbgpd-5.2.20121209_2
Name : openbgpd
Version : 5.2.20121209_2
The thing here is that my router has layer 2 access directly to one of the
networks that the edge router BGP announces to my router (172.20.104.0/22).
When my FreeBSD machine boots it will install a directly connected route for
172.20.104.0/22 in my routing table but as soon as openbgpd starts it will
install a 172.20.104.0/22 route with the nexthop of the edge router instead.
How can I prevent openbgpd from overwriting the directly connected route?
Directly connected networks should never be overwritten by a routing protocol
but I suspect this is because of the redistribute.
I've tried messing with metrics, but maybe I to create a rtable and mess around
with that?
This problem was fixed in 11.2-RELEASE, just upgrade and you will be fine.
