Introduction to OSPFv3
OSPFv3 Overview
Open Shortest Path First version 3 (OSPFv3) supports IPv6 and complies with RFC2740 (OSPF for
IPv6).
The same between OSPFv3 and OSPFv2:
z
32 bits router ID and area ID
z
Packets: Hello, DD (Data Description), LSR (Link State Request), LSU (Link State Update), LSAck
(Link State Acknowledgment)
z
Mechanism for finding neighbors and establishing adjacencies
z
Mechanism for LSA flooding and aging
Differences between OSPFv3 and OSPFv2:
z
OSPFv3 runs on a per-link basis, instead of on a per-IP-subnet basis.
z
OSPFv3 supports multiple instances per link.
z
OSPFv3 identifies neighbors by Router ID, while OSPFv2 by IP address.
OSPFv3 Packets
OSPFv3 has also five types of packets: hello, DD, LSR, LSU, and LSAck.
The five packets have the same packet header, which different from the OSPFv2 packet header is only
16 bytes in length, has no authentication field, but is added with an Instance ID field to support
multi-instance per link.
Figure 1-1
gives the OSPFv3 packet header.
