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.

Site A Router config
--------------------
interface GigabitEthernet0/0
 description Primary Wireless

interface GigabitEthernet0/1

 network 10.1.0.0 0.0.0.255

Thanks a lot.

Is there something that isn't working? If it's the Router A - switch issue, we'll need to see the config of that switch.

Beyond that, if the MW link is running at 1gb, why do you have the bandwidth set to 100mb? (not that it would matter)

Hi,

Took another look at the config and did a quick test there, it's all working fine.

Thanks for looking, I'll give you the points and close.

Cheers
