I have an OSPF over GRE configuration sending you below in which I have
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
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.
