Eigrp configuration in 7206vxr router

[manjuladevi]

We have implemented eigrp in our network.

Earlier i have configured network as 192.168.0.0/16

Now I want to restrict my network to only 192.168.128.0/18

here is my question

How can we declare network under eigrp routing protocol ,for 192.168.128.0/18 network, for cisco7204vxr router.

Hi

you mean shall I configure network like below

for configuring network 192.168.128.0/18(i.e Range between 192.168.128.0 to 192.168.191.0)

#router eigrp 105

#network 192.168.128.0 0.0.64.255

!

!

I already tried this command

I am getting below message

EIGRP: Invalid address/mask combination (discontiguous mask)

can you sujjest correct mask with wild card for this network

with regards

The problem is the 64 in the mask. Try this instead:

network 192.168.128.0 0.0.63.255

and it should work.

You should note the the "network" statement is not for advertising the network, but its used to determine which router's interfaces are participating in the EIGRP protocol

I partialy agree on this statement that when you use network command, it means you want to advertise the subnet of those network covered interface and enable the routing protocol (by dafult) on it.

If you do not want to advertise it, why do you want to include it in the routing protocol ?

You can use passive interace to disable the routing protocol in that interface but it will still advertise that interface's subnet via other interfaces.

Just my 2 cents.
