2) Verify neighbors adjencencies on all routers
* Branch1/2/3 should have Wan1/2 as neighbors
* Wan1 should have Branch1, Branch2, Branch3, Wan2, Core 1 and Core 2
* Wan2 should have Branch1, Branch2, Branch3, Wan1, Core 1 and Core 2
* Core1 should have Wan1, Wan2 and Core 2
* Core2 should have Wan1, Wan2 and Core 1
a) Branch1/2/3 should have Wan1/2 as neighbors

3) Take a look at Branch/Wan/Core routing tables. A lot of route are missing.
* Branch routers don't know routes for each other nor for Core LAN.
* Wan and Core routers don't know routes for Branch1/2/3 LAN
Correct those issues. (hint: something should be done on routers situated between two classfull networks)
Core1/2 and Wan1/2 should now know routes to all subnets. If any summary still appear in a rounting table... then you forgot to correct at least one router.
Note: auto-summary in EIGRP
From IOS version 12.2(33)SXI4 and 15.0, this command was modified. Address-family topology configuration mode was added.
The default behavior was changed to disabled.
