by broadcasting DHCP discovery frame to search a DHCP server. If the DHCP server is not present on the local subnet‚ a DHCP discovery must be forwarded by the router. And this is done by configuring an IP Helper Address on the router‚ to relay certain broadcast UDP frames (like DHCP) to a specific IP destination. In case of DHCP - the router will forward the DHCP discovery and request as unicast frames to one or more pre-configured DHCP servers. -Interestingly‚ the original client doesn’t

Classless Interdomain Routing (CIDR) was introduced to improve both address space utilization and routing scalability in the Internet. It was needed because of the rapid growth of the Internet and growth of the IP routing tables held in the Internet routers. CIDR moves way from the traditional IP classes (Class A‚ Class B‚ Class C‚ and so on). In CIDR ‚ an IP network is represented by a prefix‚ which is an IP address and some indication of the length of the mask. Length means the number of left-most

With some types of WAN interfaces‚ an external device such as a modem (Analog‚ Cable‚ or DSL) will be required to connect the router to the local point of presence (POP) of the service provider (orbit-computer-solutions.com‚ 2013). A core router is a router within the middle point of the WAN rather than at either end. The core router will be able to support multiple interfaces of the highest speed in use in the WAN core‚ and will have the ability to forward IP packets at the highest
