Rob,
If I am remembering on this one correctly there are times when it doesn't work no matter what you do. I don't think there is anything that you are doing wrong.

From: [email protected] [mailto:[email protected]] On Behalf Of Rob Sent: Tuesday, September 22, 2009 6:41 PM To: [email protected] Subject: [OSL | CCIE_RS] OSPF Routinbg issue I have been working at this for a while and am totally confused as to what is happening. I am still on Vol 3 Lab 3 and am trying to test my reachability right after redistribution. Here is the stand part. For some reason I can not figure out, R2 believes the networks behind R5 are actually reachable via R6 as long as R6 is up. If I shut down R6's Multilink interface on R2 then the routes appear as they should. As soon as R6 comes back on line R2 deleted the route and changes it back to R6. Below is an example of the loopback 1 address. The same happens for the other addresses behind the router. I also tried moving R5's loopback to area 9600 and it still does not change anything. Thanks in advance.
