How to advertise non-connected EIGRP routes

Hi,

Simple set up...2 sites, A & B....they talk via a wireless link which fails over to a backup wireless link when it's down. I have being doing some network re-designing and I want to know how to advertise the networks beyond each sides router...see diagram

Site A - Router A is the EIGRP router I am working on
Networks I want to advertise to site B - 172.16.0.0 /20 10.10.20.0 /30 192.168.4.0 /24 (DMZ - not in pic)

Site B - Router B is the EIGRP router I am working on
Networks I want to advertise to site A - 192.168.5.0 /24 10.10.40.0 /30 192.168.3.0 /24 (DMZ - not in pic)

When the primary wireless goes down I want to failover to the backup

Any idea how to configure the EIGRP here?

Thanks

Ally

The "no auto-summary" is optional.

Site A multilayer switch:
router eigrp 100
no auto-summary
network 10.0.0.0
network 172.16.0.0

Site A router
router eigrp 100
no auto-summary
network 10.0.0.0

Site B router
router eigrp 100
no auto-summary
network 10.0.0.0

Site B multilayer switch:
router eigrp 100
no auto-summary
network 10.0.0.0
network 192.168.5.0

Thanks for the reply. Surely the 10.0.0.0 without auto summary would cover my /30 networks at both sites? Do I really need to introduce EIGRP on the other routers? Can I not just somehow advertise these networks on just the routers controlling the wireless?

Thanks

Hi,

I have static routes on all the network devices but I would like router A in site A (the one controlling the wireless link) to advertise 172.16.0.0 /20, 10.10.20.0 /30 and192.168.4.0 /24 but as they are not directly connected then they are not advertised. What about adding a loopback interface for each subnet?

>I have static routes on all the network devices

Then why do you need to advertise anything? If you've got static routes to all the destinations, what else is there?

I thought it would be better for eigrp to handle all the routing, seeing as it's there.

If you don't think it's a big deal then I'll just leave it

Thanks

I think you're missing my point (or I'm missing yours).

If you've got static routes defined for all networks on all layer 3 devices, then you don't need EIGRP.

If you're running EIGRP on all layer 3 devices then you don't need static routes.

OK, I guess I'm just seeing if what I am doing is OK....thanks for replying
