Chapter1:OSPFConfiguration

This chapter describes how to configure the Open Shortest Path First protocol on the
Vyatta System.
The following topics are covered:
• OSPF Overview
• Supported Standards
• Configuring OSPF
Chapter1:OSPFConfiguration OSPFOverview

OSPF 6.5R1v01 Vyatta
OSPFOverview
Open Shortest Path First (OSPF) is a dynamic routing protocol that uses a link state
algorithm (Dijkstra), as opposed to protocols (such as RIP) that use a distance vector
algorithm. It is an interior gateway protocol (IGP) and operates in a single
autonomous system (AS). In OSPF, each router advertises the state of its own links,
or connections, in a link state advertisement (LSA), which it then multicasts to other
routers on the network. In addition, each router uses the LSAs it receives from other
routers to construct a graph that represents the network topology. To build its
routing table, the router applies Dijkstra’s Shortest Path First algorithm to find the
best path through the graph to each network in the topology. This “shortest path
tree” becomes the basis of the routing table. OSPF is hierarchical. In OSPF, the
network is broken up into “areas.” Within each area, routers possess only local
routing information. Routing information about other areas is calculated using
summarized routes exchanged between areas. This reduces the amount of network
topology information routers have to generate and maintain, making OSPF a good
choice for larger networks.
SupportedStandards
The Vyatta implementation of OSPFcomplies with the following standard:
• RFC 2328: OSPF Version 2
ConfiguringOSPF
This section presents the following topics:

• Basic OSPF Configuration
• Verifying the OSPF Configuration
This section presents a sample configuration for OSPF. The configuration example is
based on the reference diagram in Figure 1-1.
Chapter1:OSPFConfiguration ConfiguringOSPF

OSPF 6.5R1v01 Vyatta
Figure1‐1OSPFconfigurationreferencediagram
BasicOSPFConfiguration
In this section, you configure OSPF on the routers labeled R1, R2, and R3 in the
reference network diagram. The routers are advertising their routes on networks
10.0.40.0/24 and 10.0.50.0/24.
This example assumes that you have already configured the router interfaces
(including the loopback interfaces - lo); only the steps required to implement OSPF
are shown.
To create a basic OSPF configuration, perform the following steps in configuration
mode:.

10.0.20 .0/24

The output shows that routes to 10.0.0.1/32, 10.0.0.2/32, 10.0.20.0/24,
10.0.30.0/24, and 10.0.40.0/24 have been learned via OSPF (and are the selected
routes). Also, packets to those networks will be forwarded out eth5 to 10.0.50.2.
10.0.0.3/32, 10.0.50.0/24 and 10.0.60.0/24 are directly connected to R3. Directly
connected routes are selected over any that are discovered by OSPF (i.e.
10.0.50.0/24).
R3:ping10.0.20.1
Using the ping command from R3 we can confirm that we can reach hosts on remote
networks. In this case we ping an IP address on R1. This is shown in Example 1-3.
