For the network in the diagram below, use Cisco Packet tracer to design the IP subnets, assign IP addresses configure the router to allow full connectivity between all subnets:

$-$ Each of the networks in the diagram should have a subnet of $8$ IPs, including the subnet ID and the subnet broadcast except for the subnet in the main office which should have a total of $32$ Ips.

$-$ All access to the Internet should be through the main office.

$-$ All sites can ping each other and ping the Internet.

$-$ Your local network is $192\mathrm{.}168\mathrm{.}20\mathrm{.}0$ with a subnet mask of $255\mathrm{.}255\mathrm{.}255\mathrm{.}0($refer the IP subnet assignment excel sheet to find the network assigned to you$).$ This network should be divided between the sites as described above and to assign IP addresses to links connecting the routers.

$-$ For testing purposes the Internet can be assumed the two following subnets $172\mathrm{.}16\mathrm{.}10\mathrm{.}0/24$ and $172\mathrm{.}16\mathrm{.}20\mathrm{.}0/24$ and Ips assigned to both side of the link connecting the main site to the Internet as follows:

o Main site side: $10\mathrm{.}10\mathrm{.}10\mathrm{.}2255\mathrm{.}255\mathrm{.}255\mathrm{.}252$

o Internet side: $10\mathrm{.}10\mathrm{.}10\mathrm{.}3255\mathrm{.}255\mathrm{.}255\mathrm{.}252$

Hint: Your job is to design a corporate network with the above specifications. To achieve this you will need to divide the network into subnets

the IP subnet $192\mathrm{.}168\mathrm{.}20\mathrm{.}0$

how many networks there in the picture?

help me add the ip addresses use the same roters $,$PCs$,$swithches names in the picture
