OSPFv3 Overview
IPv6 OSPF protocol reserves most of the IPv4 algorithm, that is,
from IPv4 to IPv6, the essential OSPF mechanism remains un-
changed.
Both IPv6 and IPv4 contain link state databases. The link state
advertisement (LSA) is contained in link state databases and such
information in the adjacent routers should be kept synchronous.
Initial database synchronization is implemented through the data-
base exchange process, which includes exchanging database de-
scription packets, link state enquiry packets and link state update
packets. The subsequent database synchronization is maintained
through flooding with link state update messages and link state
confirmation messages.
In broadcast and non-broadcast multicast access (NBMA) net-
works, both OSPFv2 and OSPFv3 use hello message to discover
and maintain adjacency relation, elect assigned routers and back
up assigned routers. OSPFv2 and OSPFv3 also keep consistent
with each other in such aspects as neighbor determination, basic
concept of inter-area routes, introduction of AS external LSA
information and different route calculation.
Differences between OSPFv3 and
OSPFv2
As OSPFv3 is based on IPv6, OSPFv3 and OSPFv2 have many dif-
ferences.
� OSPFv3 topology is based on link, while OSPFv2 topology is
based on subnet.
