you are given an allocated $1$pv$4$ address space of $209\mathrm{.}165\mathrm{.}200\mathrm{.}128/26$ and the required number of hosts in the subnet A is $30,$ also the required number of hosts in subnet B is $14.$ find the subnet A $.$ subnet ipv$4$ address, subnet mask number of host bit in the subnet, number of useable IPV$4$ host address, first Ipv$4$ host address, last IPV$4$ host address and broadcast IPV$4$ address, also the same for subnet B$.$ the Ipv$4$ address allocation will use the first $1$pv$4$ host address in their respective subnet. the network router interface will use the last IPV$4$ host address in their respective subnet, and the switch will use the second IPv$4$ address in their respective subnet. write down the ipv$4$ address information for each device. as listed device $($pc$-$A$,$R$1-$G$0/0,$R$1-$G$0/1,$S$1,$PC$-$B$),$ IPV$4$ address of each device $,$subnet mask $,$default gateway.also configure device IPV$4$ and security settings.configure a router with R$1,$g$0/0,$ R$1,$G$0,1$ to include the following items: Task $($disable DNS lookup, router hostname R$1,$ domain name cisco.com, Encrypted privileged exec password class, console access password cisco, create an administrative user in the local database, username: admin, password:admi$1$pass, set VTY lines to use a local database, set Vty lines to accept ssh connection only, encrypt the clear text passwords, set a motd banner: No unauthorized entry allowed, interface G$0/0$ set a description, set the layer $3$ipv$4$ address, activate interface.Generate an RSA crypto key $1024-$bit modulus, save running $-$config to NVRAM. using packet tracer.
