OSPF Default Routing [7:46111]
Hey all, I am currently using the CCIE Practical sutides text and I am confused on the OSPF Default routing part. On Page 795, Karl says that is you use the DEFAULT-NETWORK x.x.x.x command generate the Deafult route you need the ALWAYS statment present in the DEFAULT-INFORMATION ORIGINATE command. Then in Lab 24, as an optional step he wants you to generate the default route and proporgate it throughout the OSPF network without using static routes and if the network becomes unavailable he does not want the default route to proporgate. Now, in his Lab walkthorough he says to put the ALWAYS statment in the DEFAULT-INFORMATION ORIGINATE command but if you do that then the deafault route will proporgate even if the network is down. My question is Why would I ever want the ALWAYS statment and is he wrong about the requierments listed abaove?

Re: OSPF Default Routing [7:46111]
Hi, If you look at the lab walk through on page 817, you will notice that the statement default-information originate always route-map condition The default route will only be propagated if the condition listed in the route-map statement is met. If it is not met, the default route will not be propagated. Things would be alot simpler if you just took out the always statement, but then again, the CCIE lab requirement may require it.

Re: OSPF Default Routing [7:46111]
Thank you for your reply :) If I keep the ALWAYS statment in there the route still propagates even when I turn/unplug the ethernet on dental_ho. If I take out the ALWAYS statment the optional requirement is met. That is if I uplug the the interface the route stops propagating. What I think is going on here is that the ALWAYS tells the router to propagate even if the route map condition is not met. I think this is a mistake in the book. But what really bugs me is that Karl said you must have the ALWAYS in there if your going to use IP OSPF DEFAULT-NETWORK command but I took out the always and everything worked fine.
