OSPF configuration
NOTE:
The LB module supports configuring OSPF only in the web interface.
Open Shortest Path First (OSPF) is a link state interior gateway protocol developed by the OSPF working
group of the Internet Engineering Task Force (IETF). Now, OSPF version 2 (RFC 2328) is used.
Configuration prerequisites
Configure the link layer protocol and IP addresses for interfaces so that neighboring nodes can
communicate with each other.
Configuration overview
Make a proper plan before configuring OSPF.
Configure OSPF routers on an area basis. Wrong configurations can cause communication failures,
routing information block, and routing loops.
An OSPF routing domain has different types of routers, such as intra-area routers, Area Border Routers
(ABRs), and Autonomous System Boundary Routers (ASBRs). OSPF can work properly only after being
enabled on a router, regardless of the router’s type.
Complete the following tasks to configure OSPF:
Table 23 OSPF configuration task list
Task Remarks
Enable OSPF Configuring OSPF globally
Required
Enable OSPF on all interfaces.
Import static routes Configuring OSPF globally
Optional
Configure OSPF to redistribute static routes.
Configuring OSPF areas
Required
Configure an OSPF area, specify the network segment
included in the area, so as to enable OSPF on the
interface attached to the specified network segment.
IMPORTANT:
This task allows you to configure one or more interfaces in
an area. You need to enable OSPF on the interface whose
primary IP address belongs to the specified network
segment; otherwise, OSPF cannot run on the interface.
