I'm looking for some direction on the following error I get in my ospfd log.
2006/05/11 04:36:55 OSPF: Route[External]: Calculate AS-external-LSA to
0.0.0.0/0
2006/05/11 04:36:55 OSPF: Route[External]: Can't find originating ASBR route

2006/05/11 04:36:55 OSPF: Route[External]: AS-external-LSA is self originated

I'm using .93a zebra. I speculate this error is because I don't have the router
that sits at my border to the Internet configured to let the rest of the routers
know it is a border router or the routers which have the above static routes are
not presenting them to the rest of the network correctly.
The above configuration works but every minute all the static routes to routers
at the edge of my main network list the above messages in the log and the routes
need to be refreshed.
My problem is I know enough about OSPF and Zebra to be dangerous not good and
several trips through Cisco's IP router and OSPF book did not fill in enough
blanks for me to be able to identify the problem. Any help would be greatly
appreciated.
Below are the configuration files for the router bordering the Internet
connection and then one of the routers that sits at an office edge and has a
static route that points to that office network.
