1. Use the up-arrow or down-arrow keys to scroll to the Add a Route menu:
? no yes 2. Select yes, and OnRamp displays:
? net default 3. Select net, and OnRamp displays the IP address of the target network, for example:
new? chg go /24 4. Select chg, then revise the IP address and mask as desired, using the procedure described under Setting the IP Address in Chapter 3.
5. When you press the OK key, OnRamp prompts you to select the output interface to which it will route packets destined for this network:
? syn0 en0 6. Select the desired interface: syn0 is the 56 Kbps leased line, and en0 is the Ethernet. Then press the OK key. OnRamp displays the Add a Gateway Menu:
? no yes 7. If you want to add a gateway, select yes. OnRamp displays the IP address of OnRamp's syn0 or en0 interface, whichever one you selected in Step 6. Because this address is on the correct subnet, it will be easy to change to the gateway address.
gtway? chg go 8. Select chg, and enter the gateway IP address as desired, using the procedure described under Setting the IP Address in Chapter 3.
9. If you don't want to add a gateway, or after you have specified a new gateway address, OnRamp displays:
? no yes
1. Use the up-arrow and down-arrow keys to select the Review Routes Menu:
? no yes 2. Select yes, and press the OK key. OnRamp displays the first IP address in the routing table, for example:
en0? no del 3. If you are satisfied with this address, select no to direct OnRamp not to delete this address, and press the OK key.
4. If you wish to delete the displayed address, select del, and press the OK key.
5. OnRamp displays the next address in the routing table. Continue using the OK key to scroll through the list of routes, deleting routes as desired.
To tell OnRamp to learn routes, follow these steps:
1. Use the up-arrow and down-arrow keys to scroll to the Configure RIP Menu:
? no yes 2. Select yes and press the OK key. OnRamp displays the Learn Routes Menu:
routes? no yes 3. If you select yes, OnRamp will acquire routes from other routers, as described above. If you select no, OnRamp will only add those routes that you enter in its routing table. If you have previously selected yes, the Learn Routes Menu displays yes first.
4. After you respond to the Learn Routes Menu, OnRamp displays the Announce Routes Menu:
routes? no yes 5. If you don't wish to announce routes, press the OK key. If you wish to announce routes, refer to Announcing Routes, next.
6. OnRamp then displays the Configuration Save Menu:
save? ok no 7. Press the OK key, or simply wait a few seconds. OnRamp saves the configuration, displaying status messages to show what is happening.
OnRamp calculates the subnet broadcast address using the Internet standard for subnet broadcast networks. However many bits are specified in the mask for OnRamp's IP address, OnRamp takes that many bits from the IP address of the Ethernet interface, and sets to one the remaining bits to the right.
For example, if the subnet mask is 26 bits (/26 on the OnRamp IP Address Menu), the first 26 bits are the network number, and the remaining six bits are all ones. If your OnRamp's IP address is 199.100.133.129, then the broadcast address is 199.100.133.191.
To tell OnRamp to announce routes, follow these steps:
1. Follow Steps 1 through 4 under Learning Routes, above.
2. At the Announce Routes Menu, select yes and press the OK key. OnRamp will send RIP packets to 255.255.255.255 and to the Ethernet subnet broadcast address, as described above.
3. OnRamp then displays the Configuration Save Menu:
save? ok no 4. Press the OK key, or simply wait a few seconds. OnRamp saves the configuration, displaying status messages to show what is happening.
Use the up-arrow or down-arrow keys to scroll through the sequence of RIP configuration menus. In the following example, OnRamp menus display that Learn Routes is off and Announce Routes is on.
