eigrp with wildcard??

hjor

I must configure eigrp between two routers. And I must enable eigrp only on the following networks

192.168.3.0 255.255.255.252
172.16.4.0 255.255.255.0

Is it just like this;

router eigrp 100

network 172.16.4.0
network 192.168.3.0
no auto-summary


OR; should I add the wildcard bits??? those, in that case, would be 0.0.0.3 and 0.0.0.255, right?

You can do it either way really. If you use the first method and have another interface with an ip address in that range it will include it also. I always use a 0.0.0.0 mask as its easier.

If you would get a question like that, and it says to enable it ONLY for those networks, then use the wildcards and the no auto-summary

And yes, the wild cards would be 0.0.0.3 and 0.0.0.255

What are the wildcards, just the broadcast host bit?

The wildcard bits specify the bits in the IP address that it cares about; 0s have to match, 1s it doesn't care about.
