Network Link-State Updates

 - Issued by multi-access areas that have more than one attached router. 

One router is elected as the Designated Router (DR) and this router issues the network link-state updates 

describing every router on the segment. 

4. 

External Link-State Updates

 - Issued by an Autonomous System Border Router and describes routes to 

destinations outside the AS or a default route to the outside AS. 

 
The format of these link-state updates is described in more detail below. 
Router link-state updates are flooded to all routers in the current area. These updates describe the destinations 

reachable through all of the router’s interfaces. 
 
Summary link-state updates are generated by Border Routers to distribute routing information about other networks 

within the AS. Normally, all Summary link-state updates are forwarded to the backbone (area 0) and are then 

forwarded to all other areas in the network. Border Routers also have the responsibility of distributing routing 

information from the Autonomous System Border Router in order for routers in the network to get and maintain 

routes to other Autonomous Systems. 
 
Network link-state updates are generated by a router elected as the Designated Router on a multi-access segment 

(with more than one attached router). These updates describe all of the routers on the segment and their network 

connections. 
 
External link-state updates carry routing information to networks outside the Autonomous System. The 

Autonomous System Border Router is responsible for generating and distributing these updates. 
 

OSPF packets can be authenticated as coming from trusted routers by the use of predefined passwords. The 

default for routers is to use no authentication. 

OSPF Authentication 

 
There are two other authentication methods: Simple Password Authentication (key) and Message Digest 

authentication (MD-5). 
 

A password (or key) can be configured on a per-area basis. Routers in the same area that participate in the routing 

domain must be configured with the same key. This method is possibly vulnerable to passive attacks where a link 

analyzer is used to obtain the password. 

Simple Password Authentication 

 

MD-5 authentication is a cryptographic method. A key and a key-ID are configured on each router. The router then 

uses an algorithm to generate a mathematical “message digest” that is derived from the OSPF packet, the key and 

the key-ID. This message digest (a number) is then appended to the packet. The key is not exchanged over the 

wire and a non-decreasing sequence number is included to prevent replay attacks. 

Message Digest Authentication (MD-5) 

 

OSPF limits the number of link-state updates required between routers by defining areas within which a given 

router operates. When more than one area is configured, one area is designated as area 0, also called the 

backbone. 

Backbone and Area 0 

 
The backbone is at the center of all other areas, all areas of the network have a physical (or virtual) connection to 

the backbone through a router. OSPF allows routing information to be distributed by forwarding it into area 0, from 

which the information can be forwarded to all other areas (and all other routers) on the network. 
 
In situations where an area is required, but is not possible to provide a physical connection to the backbone, a 

virtual link can be configured. 
 

Virtual links accomplish two purposes:
