I have created a network testing lab with CISCO Packet Tracer. I have performed the following to get a DHCP and VLAN (with Trucking) working:

  1. Configured Router interfaces (g0/0 + g0/0.10-0.50)
  2. Configured DHCP settings on Router
  3. Enabled Trunk on Router
  4. Configured VLAN on Switch
  5. Enabled Trunk on Switch

Below I post the >show run< for the router and the Switch. Workstations can gain an DHCP IP address, and VLAN segregation is working.

Workstations can ping the router but can't ping other workstations on separate VLAN networks.

I see nothing wrong with your configurations. You can use simulation mode when ping to determine what happened with ICMP packets.

  • Thanks, by using the simulation mode I was able to work out that there was a configuration error with the switch. (I had the Switch IP VLAN1 IP address, assigned to a different network then the router) – noreasonban Apr 28 '21 at 08:59
