I didn't see a reply to this and currently have the same trouble. I'd 
like to distribute my local (kernel) routes through OSPF. I managed to 
create an export policy that will distribute them one-hop ("blah" below) 
but I can't seem to get them distributed more than one hop away ("blah2" 
below was an attempt at that).

In the following configs, this router is in the middle between two other 
routers; it correctly sees the locally-connected routes from both of the 
two end-routers, but the two end-routers do not see the routes to each 
others' locally connected routes.

It's possible that I need a non-default import policy? But I'm really 
not sure.

Any help appreciated!

Thanks,
Jeff
