This section will des cribe how to set-up the P1705 & P1730 routers using each of its networking functions. Note that depending on the model of unit and what interface modules are installed, some of the configuration examples may n[...]

Applications 13 Bridging and Routing Should You Bridge or Ro ute? When connecting two networks together, the first question to ask is “should I bridge or route”? The decision to bridge or to route may be decided by how the existing networks have been already set-up. Bridging should be used when the network consists of non-routable protocols or [...]

Applications 14 Bridging An Ethernet bridge intelligently forwards Ethernet data packet traffic between connected networks. The traffic may be across the Wide Area Network (illustrated below) or, in the case of the P1730, may be between two LANs connected to the same P1730. Figure 2 -1 Networks Bridged across a W AN link Ethernet bridges simply for[...]

Applications 15 IP Routing An Ethernet IP router is used to intelligently route Internet Protocol (IP) traffic to another network. The networks may be connected across a WAN link (illus trated below) or two LANs connected to the same dual LAN P1730. Figure 2 -2 IP Networks Routed across a W AN link IP routers forward IP frames based upon their IP d[...]

Applications 16 IP Addressing Devices on an IP network are located by their IP addresses, which is a 32 bit number divided into four 8 bit fields. The IP address identifies both the network and the host device (also known as a node) on that network. The address is usually written as the four decimal values for the fields (between 0 and 255) separat[...]

Applications 17 Masks The portion of the IP address to use as the network address is specif ied by using a mask; a mask is the contiguous number of bits to be used for the network address all set to 1. When the mask is logically ANDed with an IP addres s, the resu lt is the network addr ess. The mas k is specified by ent ering the mask s ize as the[...]

Applications 18 The P1705 & P1730 allows mask sizes from 8 to 32 bits. The subnet mask size determines how many bits of the host field of the original IP network addres s will be used for the creation of subnets. In this example, specifying a mask size of 26 will produce a subnet s ize of 2 bits. Two bits gives 4 possible sub-network addresses [...]

Applications 19 IP Default Gateway An IP default gate way is an IP router tha t is resident on the local IP network that this router is connect ed to and is used to r oute IP fr ames fo r dest ination networks that do not exist in the routing table. When an IP frame is r eceived that is dest ined for a network t hat is not listed in the routing tab[...]

Applications 20 IPX Routing The P1705 & P1730 are pre-configured to operate as an IPX router. When ins talled in an IPX network, the router will learn the IPX network numbers from connected networks. It will then route the IPX frames to the appropriate destination I PX network. The IPX routing scenario may consist of one of the two following co[...]

Applications 24 PPP Overvie w Point to Point Protocol (PPP) is a connection protocol tha t allows control over the set-up and monitoring of network communications. It is used in procedures for user authentication (name and password), connection management (spoofing, bandwidth on demand, multilink), and compression. I f any these funct ions are requ[...]

Applications 25 Unnumbered Links An unnumbered link does not use network addressing on the WAN link. The WAN connection is roughly equivalent to an internal connection with each of the two end point routers oper ating as half of a complet e router that is connected between t he two endpoint LANs. When an IPCP link is set to unnumbered, the only con[...]
