Has Dialer0 managed to get an IP address ("show interface Dialer0")?

Hamid Amir · ‎04-16-2017

HI Philip

I managed to make it work with these commands

no ip dhcp use vrf connected
ip dhcp excluded-address 192.168.1.0 192.168.1.99
!
ip dhcp pool vlan1
import all
network 192.168.1.0 255.255.255.0
default-router 192.168.1.1
dns-server 212.159.13.49 212.159.13.50
lease 0 12

but the proplem i loose them when i reboot the router and i get these errors

import all
^
% Invalid input detected at '^' marker.

network 192.168.1.0 255.255.255.0

It sounds like you have a had IOS version on that router. If you have a Cisco maintenance contract like a SmartNet I would upgrade the IOS to something a bit more recent. 12.x code is getting pretty old now. 15.x is the mainstream now.

I have been using same configuration before and it was working.

thanks

Hello,

I have made a few adjustments to your configuration (in bold), can you try if you get it to work with these changes ?
