Hi Josh,
On your recommendation, I added the Cisco Press Optimal Routing book to my
Safari bookshelf. I have a question however:
Figure 2-23 shows mutual redistribution at two points between OSPF and EIGRP.
Below that figure the authors walk through a numbered sequence of route
advertisements that they say results in a permanent routing loop. I am afraid
I do not see this loop!
Their Step 5 says that "Router E redistributes this route into OSPF with a
cost of 5" but router E is not connected to the OSPF domain. Where exactly
is this loop? Is this a mistake, or am I missing something?
If they mean Router D in Step 5 instead of Router E, then I would have to ask,
isn't the 10.1.1.0/24 network an OSPF route on router D, given the 170 AD for
EIGRP externals? I do not think we need to worry about feedback into the OSPF
domain in the scenario they describe. Would appreciate any thoughts here.
I know ALL books have errata, and I am sure this book has lots of good stuff
in it.
Thanks!

there's a cisco press book "optimal routing" which
has a very good redistribution chapter that explains
the in's and out's fairly well.
