Question

An engineer redistributes 20 connected /24 subnets (10.50.0.0/24 through 10.50.19.0/24) from a static-route source into OSPF on an ASBR. The neighboring routers now carry 20 individual external LSAs, increasing their LSDB size. The engineer wants to advertise a single 10.50.0.0/19 summary into the OSPF domain from this ASBR. Which command accomplishes this?
