If we knew a bit more about your environment then we might be able to give you better answers:
- does the DWDM connect to the core 6500s?
- will you be running OSPF over the DWDM? If so will OSPF treat your site and the satellite campus as a single unified routing domain or will it attempt to keep the satellite campus as a separate routing domain (external to your site)?
- do the 6500s run a routing protocol with the border router? (are they learning a default route from the border router?)
- for the satellite campus would these questions get the same answers?
If you can provide more information we may be able to formulate better advice.
