onfigure RouterB not to assign $192\mathrm{.}168\mathrm{.}1\mathrm{.}20/24$ and $192\mathrm{.}168\mathrm{.}1\mathrm{.}21/24$ through DHCP to any device other than ServerA and ServerB, respectively. Be aware of the following details: ServerA has a MAC address of $00-18-8$B$-76-$D$6-9$E$.$ ServerB has a MAC address of $00-18-8$B$-57-$C$7-8$A$.$ Both servers are configured to use DHCP$,$ not BOOTP, to receive their IP addresses. All of the devices are connected through Ethernet media. Be aware of the following when configuring DHCP manual bindings: All DHCP clients send a client identifier $($DHCP option $61)$ in the DHCP packet. Configuring bindings for DHCP clients requires the client$-$identifier DHCP pool configuration command. The unique identification of the client is specified in dotted hexadecimal notation, for example, $01$aa$.$bbcc$.$ddee.ff$,$ where $01$ represents the Ethernet media type. The host DHCP pool configuration command can use the prefix notation $($e$.$g$./24)$ or IP address representation $($e$.$g$.$ A$.$B$.$C$.$D$)$ to identify the client network mask. In this lab, your task is to: Exclude IP addresses $192\mathrm{.}168\mathrm{.}1\mathrm{.}20$ and $192\mathrm{.}168\mathrm{.}1\mathrm{.}21$ from being
