EIGRP advertised routes - not what I expected

Hi,

I have a fairly easy EIGRP question...see diagram.

I want to have router A and router B configured with EIGRP so that when the Primary microwave wireless link goes down the spread spectrum backup link comes up after the hold time has expired. I also want to be able to advertise all the networks behind each router as follows:

Router A                              Router B
10.10.10.0 /30                     10.10.30.0 /30
10.10.20. /30                       192.168.5.0 /24
172.16.0.0 /20

There is a Layer 3 switch on 172.16.15.254 which is the default gateway for the 172.16.0.0 LAN and I am thinking that this might be used to advertise the relevant networks it connects to however when i turned on EIGRP 100 is wasn't recognised by router A.

Site B's design is a bit screwed up but that will be changing soon to be the same topology as Site A. But that isn't too important right now, I just need to get this failover working.
