Failed to find address prefix and netmask [SIMULTE]

[Cristian Villarroya]

Hi, i am trying to simulate a real VANET scenario where i have 30 LTE enodes all connected with each other.

I have this error while trying to execute it :

Failed to find address prefix (using 192.168.0.0 with specified bits 255.255.0.0) and netmask (length from 24 bits to 24 bits) for interface Highway.eNodeB1080.x2ppp19 and 1 other interface(s). Please refine your parameters and try again! -- in module (inet::IPv4NetworkConfigurator) Highway.configurator (id=5), during network initialization

When i connect only a few of enodes i dont get this error. Is it possible that the net has not enoughs ips for the connections? My config file is this:

<!-- Assign to the wlan interface of all eNodeBs and UEs one address of type 10.x.x.x, since dynamic-created UEs will be assigned one such address -->

<interface hosts="eNodeB*" names="wlan" address="10.x.x.x" netmask="255.0.0.0"/>

<interface hosts="ue*" names="wlan" address="10.x.x.x" netmask="255.0.0.0"/>

<!-- Assign 192.168.x.x addresses to all other interfaces -->

<interface hosts="*" address="192.168.x.x" netmask="255.255.255.0"/>

</config>
