You don't have a route for 172.16/16 in the config below, so ospf will not advertise it. You do have a route for a subnet of 172.16/16, so either use summary-address 172.16.0.0 255.255.0.0 or nail up a static route for 172.16.0.0 255.255.0.0 to null0 and redistribute static subnets, and then ospf can redistribute that static route.

Dear Friends, I have an OSPF over GRE configuration sending you below in which I have problem. I want to force OSPF to advertise 172.16/16 range without checking anything. And as you see I have an static route for it in routing table but again OSPF do not advertise it, only it advertise when I put one /32 subnet on loopback interface. even I put "redistribute static subnets" command with/without route-map but again do not work. I think because of having my providers address range in my static routes, routers and ospf confused when wanna advertise routers.
