Hi$!$ I need some help with building a network in Cisco packet tracer.

I need to build the one, as it shown on the picture attached.

Also the requirements are

OSPF is fully converged and all devices will be able to either ping each

I need the list of the command to enter on each switch and router, and if possible advice how to configure the PC'sFigure $1$ MultiArea OSPF network topology

So$,$ on the picture there are $3$ routers Alpha, Beta and Gamma, and Switch.

Alpha has an OSPF $321$ with the network $3\mathrm{.}0\mathrm{.}0\mathrm{.}0/24$

Delta has an OSPF $111$ with the network $4\mathrm{.}0\mathrm{.}0\mathrm{.}0/24$

Gamma has an OSPF $123$ with the network $2\mathrm{.}0\mathrm{.}0\mathrm{.}0/24$

Also there is a server linked to the router Alpha

PC$1$ linked to the router Delta

PC$2$ linkied to the router Gamma

can I have a spefic commands to configure multiarea OSPF in this network, for all routers, switch and PC$?$ Thank you in advance
