Parameter 

Description 

Options 

The optional capabilities supported by the router. 

I-bit 

The Initial bit. When set to 1, this packet is the first in the sequence of Database 

Description packets. 

M-bit 

The More bit. When set to 1, this indicates that more Database Description packets 

will follow. 

MS-bit 

The Master Slave bit. When set to 1, this indicates that the router is the master during 

the Database Exchange process. A zero indicates the opposite. 

DD Sequence Number 

User to sequence the collection of Database Description Packets. The initial value 

(indicated by the Initial bit being set) should be unique. The DD sequence number 

then increments until the complete database description has been sent. 

 
The rest of the packet consists of a list of the topological database’s pieces. Each link state advertisement in the 

database is described by its link state advertisement header. 
 

Link-State Request packets are OSPF packet type 3. After exchanging Database Description packets with a 

neighboring router, a router may find that parts of its topological database are out of date. The Link-State Request 

packet is used to request the pieces of the neighbor’s database that are more up to date. Multiple Link-State 

Request packets may need to be used. The sending of Link-State Request packets is the last step in bringing up 

an adjacency. 

Link-State Request Packet 

 
A router that sends a Link-State Request packet has in mind the precise instance of the database pieces it is 

requesting, defined by LS sequence number, LS checksum, and LS age, although these fields are not specified in 

the Link-State Request packet itself. The router may receive even more recent instances in response. 
 
The format of the Link-State Request packet is shown below:
