Question : eigrp config

Hi,

I have to reconfigure our eigrp. currently we use the network statement: network 192.0.0.0

I need to be more specific to only advertise routes connected to each router.

I need advice on how to do this if I give and example of a simple router  can someone suggest the config:

sorry this is a real easy one but I want to be sure i doing it right.

for eg:

fastethernet 0/1
ip address 192.168.4.1 255.255.255.0

serial 0/0
ip address 202.32.115.129 255.255.255.252

serial 0/1
ip address 202.32.178.133 255.255.255.252

serial 1/1
ip address 202.32.155.50 255.255.255.252

What would the network statement be? I guess I am confused about adding the wan connections??
Cheers

Answer : eigrp config

>we are using network statement 192.0.0.0.
The network statement in EIGRP does mean that subnet is broadcast. It simply means that these networks will participate in EIGRP. Do you use a netmask statement with that network? Typically EIGRP will only go to the classful boundary unless otherwise specified. Since 192.0.0.0 is a classful network 192.0.0.x/24 I wouldn't think that all of your links would be covered. For example using your posted example, I chose to use 2 network statements

>router eigrp 101
 network 192.0.1.0 <== without a mask this is classful and covers both serial interfaces 192.0.1.x
 network 192.0.5.0  <== serial 1/1 interface IP is not covered in the above

Again, the network statement determines which interfaces will participate, not which networks will be advertised.

Make sure none of your routers has auto-summary enabled.

>If someone at a remote site connects the vpn back without removing the main connection we get into an issue with a routing loop when the main link comes back,
Is this a manual process to switch from one to the other? ? ?
