Scott you got me all confused with this Split Horizon thing - please feel
free to weight in with more details if you could. Here is my take on this:
What Dave is seeing is a normal behavior of Split Horizon. R3 and R4 would
advertise R1's Lo0 to each other as long as those routes pertain to their
path that connect them to R2 - you will only see one route in your routing
table unless you have a variance set up or they are exactly equal path
routes, but you would see all those routes in your EIGRP topology table. Now
with EIGRP, they would not be able to advertise the route back to their
interface that they have picked as best path direction - even though that
router was learned from a different interface - in this case, assuming that
R3 picked R2 as its best path, R3 would not advertise the path via R4 to to
R2.
My issue in your prior is: "and then the learning router would not advertise
R1's Lo0 back to the other neighbor"
Please correct me if I'm wrong.
Thx
