Your absolutely right about the BGP-to-BGP's. Since you can't have two
instances running, you can't redistribute.
I disagree about excluding IGP-to-BGP and BGP-to-IGP redistribution. While
it's not recommended in the real world, it can still be done, so we should
know how to do it. By the way, one of the main reasons not to do this is to
avoid BGP learning a route from IGP that it learned from BGP... :-)

I sent out quite a few, too... when it's 'done', I'll post it.
comments within for the redistribution matrix
I thought we covered these below already, which were all the IGP to IGP
redistribution rules...

> * IGRP to EIGRP
> * EIGRP to IGRP
> * EIGRP to EIGRP
> * EIGRP to OSPF
> * RIPv2 to EIGRP
These don't really apply from a redistribution perspective - correct me if
i'm wrong
> * EIGRP to eBGP
> * RIPv1 to eBGP
> * RIPv2 to eBGP
> * IGRP to eBGP
> * eBGP to RIPv1
> * eBGP to RIPv2
> * eBGP to IGRP
> * eBGP to EIGRP
> * eBGP to OSPF
> * eBGP to iBGP
> * eBGP to iBGP
> * ISIS to eBGP
this is BGP routing, and you're not allowed to have two BGP processes
running on the same router
> * iBGP to eBGP
> * iBGP to iBGP
This is the final list that we need, and we also need the 'special rules'
for classless to classful routing protocols...
