I know this is an old thread, but I was looking for the same information as you. As yourself, I couldn't find a way to change the metric-type of EIGRP routes using route-maps. In my desperation, I found a good solution for my use case. Maybe it can be useful for you too.
What I did, is using summary-addresses. Summary-addresses are redistributed as EIGRP internal routes.
My use case is that I needed to avoid some asymmetric traffic in a network. I have 2 Data Centers, and each one has it's own WAN exit. EIGRP is injecting a default route only (0/0) to the DCs. So, each DC chooses it's local WAN exit due to the administrative distances of the routes. My customer wanted to use just the WAN exit in the main Data Center. The issue is that the routes are redistributed like this:
IP_Cloud1 --> 0/0 --> WAN1 <--> EIGRP <--> DC1 <--> MP-BGP <--> DC2 <--> WAN2 <-- 0/0 IP_Cloud2
When WAN1 inserts the 0/0 route to EIGRP in DC1, it's already an external route. Same with DC2 and WAN2. It has an AD of 170.
When DC1 and DC2 share the default routes they are receiving from EIGRP, it's done using MP-BGP (this is an ACI pod). MP-BGP has an AD of 200; so that's why always the EIGRP local route is inserted in the routing table of the DC switches.
What I did is: in the WAN router interface that is attached directly to to my DC switches, I added a summary-address with an AD of 254 (if it's 255, it won't be advertised). This will create an entry in the WAN router, but since the AD of 254 is still worse than the AD of the route that this router is receiving from a different layer (which is 170 because it's being also learnt from EIGRP from a different device), the WAN router is still installing the route that it's receiving from EIGRP locally, but now, the route that it announces into my DC switches, is an internal route.
show ip route on DC switches, before ip summary address configuration:
0.0.0.0/0, ubest/mbest: 1/0 *via 10.2.1.2, vlan224, [170/51712], 00:00:17, eigrp-default, external
show ip route on DC switches, after ip summary address configuration:
0.0.0.0/0, ubest/mbest: 1/0 *via 10.2.1.2, vlan224, [90/768], 00:00:27, eigrp-default, internal
Now I just need to make some modifications in the ACI fabric to change the AD for EIGRP internal routes, and I will have solved the problem. Anyway, just wanted to give this information for whoever needs it.
PD: I know it's not an elegant solution, and it will not scale very well because it would be a pain to add hundreds or thousands of subnets in the interface configuration, but it works for me since I only need to advertise a default route.

@ leolaohoo: This is actually the spare 4402, so I do have another one, is there anything I can do with that? Like copying something from the good one to the faulty one? @ George Stefanick: I'm not even getting the CISCO screen :S That's what's giving me the creeps. Any idea folks?

Hi all, Hope you can help with this. I have a WLC 4402 that was showing an error on the seconday image when looking at the MONITOR section on the web interface. So I decided to upload the same image that we are using on another WLC 4402 that we have and after doing so and restarting the system, now it's not doing anything. It's not throwing the CISCO screen when consoled to it, not responding to pings to the service port, nothing. Only the STATUS and PS2 leds are lit on solid, apart from that, is doing nothing. I tried to press ESC a lot of times on the console screen, tried different conection speeds, different console cable. NOTHING! Please help. I'm really coming mad (insane) on this one.
