Chapter 54. OSPFv3 Configuration
Overview 54.1
OSPFv3 is an IGP routing protocol developed by the OSPF working group of IETF for the IPv6 network.
OSPFv3 supports the IPv6 subnet, the mark of the external routing information and the packet’s
authentication.
OSPFv3 and OSPFv2 have a lot in common:
 Both router ID and area ID are 32 bit.
 The following are the same type of packets: Hello packets, DD packets, LSR packets, LSU packets and
LSAck packets.
 Having the same neighbor discovery mechanism and the same neighborhood generation mechanism
 Having the same LSA expansion mechanism and the same LSA aging mechanism
The main differences of both OSPFv3 and OSPFv2 are shown below:
 OSPFv3 is running on the basis of link, while OSPFv2 is running on the basis of network segment.
 OSPFv3can run multiple instances on the same link.
 OSPFv3 labels its neighbor through router ID, while OSPFv2 labels its neighbor through IP.
 OSPFv3 defines 7 classes of LSAs.
The following table shows some key functions in the realization of the OSPFv3 functions.
Key attributes Description
Stub domain Supports the stub domain.
Route forwarding Means that routes that are learned or generated by any
routing protocol can be forwarded to the domains of other
routing protocols.In the autonomous domain, it means that
OSPFv3 can input the RIPng learned routes.
The routes learned by OSPFv3 can also be exported to
RIPng.Between the autonomous domains, OSPFv3 can
import the BGP-learned routes; OSPFv3 routes can also be
exported to the BGPs.
Parameters of a
routing interface
The following are configurable interface parameters: output
cost, retransmission interval, interface's transmission delay,
router’s priority, interval for judging the shutdown of a router,
hello interval, and authentication key.
Virtual link Supports the virtual link.
OSPFv3 Configuration Task List 54.2
OSPFv3 demands the switchover of routing data between in-domain router, ABR and ASBR. In order to
