Expand description
The Link State Request packet (v3)
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Database Description packets with a neighboring router, a router may find that parts of its link-state database are out-of-date.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.
A router that sends a Link State Request packet has in mind the precise instance of the database pieces it is requesting. Each instance is defined by its 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 LSA instances in response.
The sending of Link State Request packets is documented in Section 10.9 of [OSPFV2]. The reception of Link State Request packets is documented in Section 10.7 of [OSPFV2].
