Set up the following topology and determine what is necessary to ping from PC$1$ to PC$4$ successfully. There is only one correct solution. IP Addresses, Subnet Masks, Routing Protocols, etc. Configure VLANs for the appropriate switch interfaces and IP addresses.You may refer to Discussion Chapter $11$ on VLAN$($s$)$ inter VLAN routing.Once the entire NW has been configured properly all Hosts will successfully ping to all Hosts.Configure with the following table.Addressing Scheme:PC$1$; $172\mathrm{.}16\mathrm{.}40\mathrm{.}10/24$PC$2$: $172\mathrm{.}16\mathrm{.}10\mathrm{.}10/24$PC$3$: $172\mathrm{.}16\mathrm{.}50\mathrm{.}10/24$ to switch $1$ interface f$0/3$PC$4$: $172\mathrm{.}16\mathrm{.}50\mathrm{.}254/24$ to switch $1$ interface f$0/4$Router $1$: Interface Fa$0/1172\mathrm{.}16\mathrm{.}40\mathrm{.}1/24$Router $0$: Interface Fa$0/1172\mathrm{.}16\mathrm{.}10\mathrm{.}1/24$Switch $1$: Interface Fa$0/1172\mathrm{.}16\mathrm{.}50\mathrm{.}1/24$ to Router $2$ interface f$0/1.$Switch $1$: Interface Fa$0/2172\mathrm{.}16\mathrm{.}50\mathrm{.}129/24$ to Router $2$ interface f$0/2$Router $1$ to Router $0$ serial interfaces: $172\mathrm{.}16\mathrm{.}20\mathrm{.}1/24$ and $172\mathrm{.}16\mathrm{.}20\mathrm{.}2/24$Router $1$ to Router $2$ serial interfaces: $172\mathrm{.}16\mathrm{.}30\mathrm{.}1/24$ and $172\mathrm{.}16\mathrm{.}30\mathrm{.}2/24$ Please include a step by step guide on what commands to use and where to put them to get the lights green and everythinh to ping
