Sample Revision of the OSPF Configuration File This chapter discusses how to modify the files that configure the Open Shortest Path First (OSPF) protocol. Note: To configure the BANDIT to use OSPF, see Configuring the BANDIT for OSPF or BGP Modifying the OSPF Configuration File You can modify the OSPF configuration file, ospf.conf, via an ASCII text editor or from the BANDIT menus. To use an ASCII text editor, open the file and make changes as appropriate. This document discusses editing the file through the BANDIT menus. 1 Log In on the BANDIT menu.

3 Sample Revision of the OSPF Configuration File Page 3 Note: The system automatically creates the default file /etc/ospf.conf when the software is loaded. The BANDIT always uses ospf.conf for OSPF configuration. This procedure shows you how to edit that file. 6 To review and edit the listed OSPF configuration file, press the Enter key. The line code for the file is displayed. 1! 20 ospf router-id To see more of the listing, press the Enter key again. The next 20 lines of the file are displayed. 21 area 0 range /24 22 area 1 range /24 23!area authentication 24 area 2 virtual-link hello-interval 20 25!compatible rfc !Enable logging 8 To see more of the listing, press the Enter key again. The next 20 lines of the file are displayed. Note: If you have reached the end of the file, the first 20 lines are displayed again. For reference, we display here the entire sample listing.

You will need to modify the lines for your network. A line that begins with an exclamation point (!) is a comment. To add comments, start a line with an exclamation point. To make a line active, remove the initial exclamation point from a commented line. In this example: Line 19 identifies this network and area. Line 20 identifies the BANDIT s WAN IP address. Line 21 advertises this area s network addresses. Line 22 advertises another area s network s addresses. If you want to advertise additional interface networks, insert lines after line 22. As this listing shows, OSPF can set up authentication between routers so that they will share information. If authentication is enabled, ensure that all password parameters are correct. You need to modify the file to reflect the OSPF area for this BANDIT device. The following steps are examples of the way to modify lines. Ask your network administrator for all IP addresses and other network information for this BANDIT s OSPF configuration.

5 Sample Revision of the OSPF Configuration File Page 5 9 Line 1 in this example is a comment, but it provides only spacing. Do the following to add some information. a While the listing is displayed, type m to modify a line. Enter line number to modify: b Type the line number you wish to modify and press the Enter key. (In this example, type 1 and press the Enter key.) Enter line below: c Type the line exactly as you want it to appear. Note: Do not type a line number; the system assigns line numbers each time it displays the file. Otherwise, type the line exactly as you want it to appear. (Be sure to start the line with an exclamation point, so that the system will see the line as a comment instead of an executable command.)! Authentication between routers d When you have finished typing the line, press the Enter key. The OSPF configuration file is displayed again, with the new line in place. Line 1 now shows some information about the routine.

In this listing, line 20, as shown below, identifies the BANDIT. 20 ospf router-id To modify the line, do the following: a While the listing is displayed, type m to modify a line. Enter line number to modify: b Type the line number you wish to modify and press the Enter key. (In this example, type 14 and press the Enter key.) Enter line below: c Type the line exactly as you want it to appear. Note: Do not type a line number; the system assigns line numbers each time it displays the file.

7 Sample Revision of the OSPF Configuration File Page 7 Note that we also do not type an exclamation point, because this will be a live command. Otherwise, we type the line exactly as it appears in the listing, substituting the IP address for the BANDIT s WAN port. ospf router-id d When you have finished typing the line, press the Enter key. The OSPF configuration file is displayed again, with the new line in place. Line 20 is now a live, executable command, assigning the BANDIT s WAN IP address. 1! Authentication between routers 20 ospf router-id For reference, we display here the rest of the listing. 21 area 0 range /24 22 area 1 range /24 23!area authentication 24 area 2 virtual-link hello-interval 20 25!compatible rfc !Enable logging Note: You need to include all the networks that you want this BANDIT to advertise. Insert them after line 22. (Displayed line numbers will change to accommodate insertions.)

8 Page 8 Routing Module, Document To insert a line, do the following: a When the listing is displayed, type i to insert a line. 1! Authentication between routers 20 ospf router-id area 0 range /24 22 area 1 range /24 23!area authentication 24 area 2 virtual-link hello-interval 20 25!compatible rfc !Enable logging Enter line number to Insert After(0 to prepend): b Type the line number that the inserted line will follow and then press the Enter key. (In this example, we want to indicate another network for this BANDIT to advertise, so we will insert a line after line 22. Type 22 and press Enter.) Enter line below: c Type the new information, using line 22 as a guide. Then press Enter.

The finished file will probably be similar to the following.
