OSPF generate default route
I have configuration problem: how I can generate default route in OSPF area? Generate, not redistribute from static kernel route or other routing protocol. Generate, not installed into kernel routeng table. Same as for Cisco 'default-information originate always'. Next question: conditional advertise default route (for example -- if present announce in BGP to some network).

default route not present in kernel nor other routing protocols, only prpopagate to OSPF area (from border router with full view BGP, for example).

Santiago's point is, that you don't have to connect such a static protocol to anything else. So it does not have to be connected to kernel protocol. Ondrej

OK, what about conditional propagate? For example where 8.8.8.0/24 present in table? (ex: two full-view BGP router with OSPF between, need to switch to backup gateway)

This is not supported. (Although planned.) -- Elen sila lumenn' omentielvo Ondrej 'SanTiago' Zajicek (email: santiago@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."

OK, what about conditional propagate? For example where 8.8.8.0/24 present in table? You can use 'aggregate' protocol (available in FreeBSD port) with 'mandatory route' to achieve conditional advertisement.
