Basic OSPF Configuration
Before you can configure other OSPF features, you must first enable OSPF and specify the interface
and area ID.
Configuration Prerequisites
Before configuring OSPF, perform the following tasks:
z Configuring the link layer protocol
z Configuring the network layer addresses of interfaces so that the adjacent nodes are reachable to
each other at the network layer
Basic OSPF Configuration
Basic OSPF configuration includes:
z Configuring router ID
To ensure stable OSPF operation, you should determine the division of router IDs and manually
configure them when implementing network planning. When you configure router IDs manually, make
sure each router ID is uniquely used by one router in the AS. A common practice is to set the IP address
of an interface on the router to the router ID.
z Enabling OSPF
The switches support multiple OSPF processes. To enable multiple OSPF processes on a router, you
need to specify different process IDs. OSPF process ID is only locally significant; it does not affect the
packet exchange between an OSPF process and other routers. Therefore, packets can be exchanged
between routers with different OSPF processes IDs.
z Configuring an area and the network segments in the area. You need to plan areas in an AS before
performing the corresponding configurations on each router.
When configuring the routers in the same area, please note that most configurations should be
uniformly made based on the area. Wrong configuration may disable information transmission between
neighboring routers and even lead to congestion or self-loop of routing information.
Follow these steps to perform basic OSPF configurations:
