4.3 Basic OSPF Configuration

Before you can configure other OSPF features, you must first enable OSPF and specify
the interface and area ID.
4.3.1 Configuration Prerequisites
Before configuring OSPF, perform the following tasks:
Configuring the link layer protocol
Configuring the network layer addresses of interfaces so that the adjacent nodes
are reachable to each other at the network layer
4.3.2 Basic OSPF Configuration
Basic OSPF configuration includes:
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 router ID to the IP address of an interface on the router.
Enabling OSPF
VRP (
versatile routing platform
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.
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.
