+ <br>\r
+ <br>This will cause an opening of a new window:\r
+ <br><img src="43.jpg">\r
+ <br>\r
+ <br>This window allows the user to define a routing table for the selected router.\r
+ <br>The structure of a routing table is a list of lines where each line contains 4 elements:\r
+ <br>\r
+ <table cellpadding="14">\r
+ <tr>\r
+ <td valign="top"><b>Network destination</b></td>\r
+ <td>Used to define destination network. This value is compared with part of datagram's target\r
+ <br>IP address according to <b>Netmask</b> value. The network destination value might be either\r
+ <br>IP address of one of the defined networks or an address that aggregates several networks\r
+ <br>(supernet).\r
+ <br>For example in order to route a datagram to either network 192.168.10.0 or\r
+ <br>192.168.11.0 using same <b>Interface</b> of selected router, the user may define network\r
+ <br>destination to be 192.168.0.0 with appropriate <b>Netmask</b> (255.255.0.0).</td>\r
+ </tr>\r
+ <tr>\r
+ <td valign="top"><b>Netmask</b></td>\r
+ <td>Used to differ the prefix of datagram's target IP, which should be compared with the current\r
+ <br>entry's <b>Network destination</b> value.</td>\r
+ </tr>\r
+ <tr>\r
+ <td valign="top"><b>Next hop</b></td>\r
+ <td>Used to define a router to which a datagram will be forwarded from current router in case\r
+ <br><b>Network Destination</b> matches to defined prefix of datagram's target IP address.\r
+ <br>Two different cases of selection are available for this field:\r
+ <ol type="i" start="1">\r
+ <li>In case the datagram's destination network is not one of the networks that selected router\r
+ <br>is connected to, the user should select the next hop to be a router's IP address that will\r
+ <br>handle this datagram further.</li>\r
+ <li>In case the router is connected directly to datagram's destination network,\r
+ <br>then the user should select the IP address of the selected router (on this network).\r
+ <br>In other words, in case the value of this field is an address of the selected router\r
+ <br>itself, the system will attempt to send the datagram directly to the target host.</li>\r
+ </ol></td>\r
+ </tr>\r
+ <tr>\r
+ <td valign="top"><b>Interface</b></td>\r
+ <td>Used to select router's network connection to which datagram will be forwarded if this routing table entry\r
+ <br>will match the datagram's target IP address.</td>\r
+ </tr>\r
+ </table>\r
+ <br> In addition, to the right of each line, there is a "<b><i>Remove</i></b>" button that, when pressed, deletes the appropriate line from the table.\r
+ <br>\r
+ <br> To add a new empty line to routing table the user should click "<b><i>Add new line</i></b>" button. The empty line will appear\r
+ <br> and it must be properly configured, before saving the table or moving to another line in routing table.\r
+ <br>\r
+ <br> In order to create basic routing table, which will be based on current configuration, the user may click, "<b><i>Add entries for\r
+ <br> each interface</i></b>" button. This will add a line for each connected network, which configures the ability to\r
+ <br> forward datagrams directly to hosts that are connected to selected router's network.\r
+ <br>\r
+ <br> In order to create a default routing entry in routing table (to indicate where to forward a datagram that does not\r
+ <br> match any of other entries) the user may click "<b><i>Add default entry</i></b>" button. This will add a line where\r
+ <br> network destination and netmask will match to any datagram and all user has to do is to configure where the datagram\r
+ <br> should be forwarded.\r

+ <br> After the user has defined an IP address for a network, the network is responsible for allocating IP\r

+ <br> is defined by network address. When creating a new host or connecting a router to the network, a free\r
+ <br> address from the pool is allocated. When a host is being removed or a router is being disconnected\r
+ <br> from a network, its IP address is deallocated and returned to pool.\r
+ <br>\r
+ <br> Please note that allocation of addresses is not necessarily successive (e.g. for class C network\r
+ <br> 192.168.2.0 allocation of addresses for 2 hosts might return 192.168.2.1 and 192.168.2.3).\r
