Open Shortest Path First Configuration
Alteon supports the Open Shortest Path First (OSPF) routing protocol. The Alteon implementation conforms to the OSPF version 2 specifications detailed in Internet RFC 1583.
OSPF is designed for routing traffic within a single IP domain called an Autonomous System (AS). The AS can be divided into smaller logical units known as areas. In any AS with multiple areas, one area must be designated as area 0, known as the backbone. The backbone acts as the central OSPF area. All other areas in the AS must be connected to the backbone. Areas inject summary routing information into the backbone, which then distributes it to other areas as needed. For more information on how to configure OSPF, refer to the Alteon Command Line Interface Application Guide.

OSPF Configuration Menu Options (/cfg/l3/ospf) 
Command Syntax and Usage
aindex <area index (0-2)>
 
Displays the Area Index menu. This area index does not represent the actual OSPF area number. To view this menu, see /cfg/l3/ospf/aindex Area Index Configuration Menu.
range <range number (1-16)>
 
Displays the Summary Routes menu for up to 16 IP addresses. To view this menu, see /cfg/l3/ospf/range OSPF Summary Range Configuration Menu.
Default: enable
if <interface number (1-255)>
 
Displays the OSPF Interface configuration menu. To view this menu, see /cfg/l3/ospf/if OSPF Interface Configuration Menu.
Default: enable
virt <virtual link (1-3)>
 
Displays the Virtual Links menu used to configure OSPF for a virtual link. To view this menu, see /cfg/l3/ospf/virt OSPF Virtual Link Configuration Menu.
md5key <key ID (1-255)>
 
Displays the OSPF MD5 Key menu to assign a string to MD5 authentication key. To view this menu, see /cfg/l3/ospf/md5key OSPF MD5 Key Configuration Menu.
host <host entry number (1 – 128) (1 – 1024 in version 31.0.2 and later)>
 
Specifies the OSPF host route.
Host routes are used for advertising network device IP addresses to external networks to perform server load balancing within OSPF. It also makes Area Border Route (ABR) load sharing and ABR failover possible.
Values: 1 – 128 (1 – 1024 in version 31.0.2 and later)
To view the OSPF Host Entry menu, see /cfg/l3/ospf/host OSPF Host Entry Configuration Menu.
redist <fixed|static|rip|ebgp|ibgp>
 
Displays the Route Distribution menu. To view this menu, see /cfg/l3/ospf/redist OSPF Route Redistribution Configuration Menu.
lsdb <LSDB limit (0-2000, 0 for no limit)>
 
Sets the link state database limit.
default <metric (1-16777215) metric-type 1|2> |none
 
Sets one default route among multiple choices in an area. None means no default.
on
 
Enables OSPF.
off
 
Disables OSPF.
cur
 
Displays the current OSPF configuration settings.
