Open in nodes of same subnet. Whereas IPV6 based

Open a shortest path first protocol is used to
give internet protocol information by the help of single Autonomous System (AS)
in internet protocol network. In RFC2328 (1988), OSPF was defined as version2
for IPV4,whereas in RFC5340(2008) there was new update of OSPF as a version 3
for IPV6.

There are so many benefits of open shortest path
first version 3 such as;

rise the scalability.

OSPFv3
enhances OSPFv2 adaptability for IPv4 by utilizing the Intra-Area-Prefix
Link-State Advertisement (LSA) (LS sort 0x2009) to promote associated prefixes.
Since IP tending to is presently isolated from the computation of the Shortest
Path First (SPF) tree, OSPFv3 inside switches don’t need to surge the whole
territory with another Type 1 LSA to different switches in a similar zone when
a topology change happens, for example, when a prefix is included, a current
prefix is erased, or its metric is changed, setting off another SPF estimation .
This is particularly beneficial for substantial IPv4-based single-region
topologies with heaps of access gadgets.

MOBILITIY

There
are limitation in mobile operation because mobile network based on IPV4, which
can only support peering in nodes of same subnet. Whereas IPV6 based on OSPFV3
there is number of addressing and peering limits. OSPFV3 does not help IPV4
nodes as originally defined. This feature help IPV4 nodes on different subnet
to peer using link-local addresses.

                                      

Moreover OSPFV3 addresses families overview and control
packets. OSPFv3 runs on top of IPv6 and uses IPv6 link local scope
(FE80::/10) for control packets. As a consequence, it is required that IPv6 be
enabled on an OSPFv3 link although the link may not be participating in any
IPv6 routing.
