Yes - that will be a fine solution for your redundant multi-vendor
backbone... er, wait. Sorry, forgot what list I was on :P Also, I had
a look at this, and in the QA section, I got a good laugh from this

Q. How do I deploy Cisco PfR in networks not running internal BGP
(iBGP) within the enterprise?
A. To synchronize routing within the enterprise and take advantage of
new optimal Cisco PfR routes, route redistribution into the local
Interior Gateway Protocol (IGP; for example, EIGRP, OSPF, or RIP)
needs to occur. Static routes injected by Cisco PfR are tagged by an
identifier that can be specifically redistributed. On the other hand,
BGP routes are usually not redistributed into IGP.


(Sorry - but this just wouldn't fly in a service provider environment)
