How to share a route from OSPF to BGP?

Question

System administration

In the OSPF zone, the Mikrotik router (M-OSPF-15) will feed traffic.
On M-OSPF-15, a route is configured for accessing the Internet:

#      DST-ADDRESS        PREF-SRC        GATEWAY            DISTANCE
 0 A S  0.0.0.0/0                          192.168.18.2              1

and distributed-default is registered so that other routers in the OSPF zone pick up this route and have access to the Internet.
How now to share this route for the BGP protocol? It is necessary that routers from the iBGP zone know the route to the Internet.
