Scenario: I have 25 sites which we have or are dropping Cisco 871
(12.4(4)T7) routers. We have a hub (CISCO 2801 12.4.(9)T) where we
have a few app servers are hosted. All sites have static IP
addresses.

Problem: I have attempted to create multipoint connections from all
these sites to the hub while implementing EIGRP to allow spoke to
spoke dynamic routing. It seems that my current 871 images do not
support this feature. They do support OSPF and nhrp which I can and
will use if necessary but for familiarity and future conformity sake I
would like to stick with an EIGRP environment. What IOS will allow
this protocol on the 871 platform? It sure beats the heck out of huge
point to points in all these sites with possibly 20 or so more being
acquired in the next 6 months.

Teach a man to fish... If anyone feels that I'm heading down the
wrong path with this plan please feel free to point in another
direction. I suppose that brushing up on my OSPF configurations would
do me good in the long run anyway. If I have a similar IOS function
situation arise in the future how can I dig for this myself? We do
have a CISCO partner account and I am certified but I get so lost
digging through all the image releases and notes that it feels like
I'm stabbing in the dark sometimes with these lower end devices.

It's late, I'm punchy and crosseyed so I hope this makes sense.
Thanks in advance.

I have found the answer. For anyone else hitting this in future:
You need to have the Advanced IP IOS and 8 MB flash (@$80 our Ingram
Price) to run EIGRP with 800 series routers.
