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. interface Tunnel0
