OSPF Create and Originate Default Route

Hello! I use the OSPF module of the bird, however I use several different tables in both the module and the Linux kernel, and in general I need to create and distribute the default route. I saw in other discussions that the folks there are no problems in reading the route in the kernel table, and so redistribute it, I remember that this is not my case, I do not have the default route in these kernel tables. Does anyone have any idea how I will do this? -- André Carlim StubNetwork
