Manually Configuring your Modem
Authentication | None: No authentication. |
Required | Password: A password authentication key is |
| |
| included in the packet. If this does not match |
| what is expected, the packet will be discarded. |
| This method provides very little security as it |
| is possible to learn the authentication key by |
| watching RIP packets. |
| MD5: An algorithm that is used to verify data |
| integrity through the creation of a |
| digest from data input (which may be a message |
| of any length) that is claimed to be as unique to |
| that specific data as a fingerprint is to a specific |
| individual. |
|
|
Authentication | Password or MD5 Authentication key. |

Routing Table
Parameter | Description |
|
|
Flags | Indicates the route status: |
| C = Direct connection on the same subnet. |
| S = Static Modem |
| R = RIP (Routing Information Protocol) assigned |
| route. |
| I = ICMP (Internet Control Message Protocol) |
| Redirect route. |
|
|
Network | Destination IP address |
Address |
|
|
|
Netmask | The subnetwork associated with the destination. |
| This is a template that identifies the address bits |
| in the destination address used for routing to |
| specific subnets. Each bit that corresponds to a |
| “1” is part of the subnet mask number; each bit |
| that corresponds to “0” is part of the host number. |
|
|
Gateway | The IP address of the Modem at the next hop to |
| which frames are forwarded. |
|
|
Interface | The local interface through which the next hop of |
| this route is reached. |
|
|
Metric | When a Modem receives a routing update that |
| contains a new or changed destination network |
| entry, the Modem adds 1 to the metric value |
| indicated in the update and enters the network in |
| the routing table. |
