Michael,
I duplicated the setup but can't duplicate the problem. Can you send relevent p
ortions of your configs (BGP and OSPF parts) for all of the routers? Also the I
P table for Telluride would be helpful.
Thanks.

a debug on the Telluride router I get the output below. I cannot seem to find
what this output means anywhere on the Cisco site. I am assuming it's got somet
hing to do with these routes not being able to be propagated to Alta.
