Can I know what this command does - 'ip route 0.0.0.0 255.255.255.255 x.x.x.x'. Is it just when a packet matches the ip 0.0.0.0 then it would be forwarded to x.x.x.x? If so, when will a packet have the ip 0.0.0.0?
IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 00:04:23:57:a5:7a
The above IP Route Command you mentioned will be used for this type BOOTP / DHCP Requests. Because, Basically systems getting their IP Address assigned during BOOTP & via DHCP will request using their MAC Address Only.
At this Case, their initial IP will be 0.0.0.0 & it need to be matched fully(255) since it may be BOOTP / DHCP & then request is fwd to the DHCP Server(x) where their MAC Address will be matched against "Mac-address-table" & IP will be released based on the Availaibility & Lease Condictions.
