Page 72 ZXR10 ZSR V2 Configuration Guide (IPv6) Compared with OSPFv2, OSPFv3 has almost the same working mechanism but has also revised OSPFv2 to support the IPv6 address format. The following sections describe in detail the similarities and differences between OSPFv2 and OSPFv3.
Page 73: Chapter 6 Ospfv3 Configuration
The Hello packet does not contain the address semanteme but contains an à interface ID used by the router to identify the link. If the router becomes the DR on the link, the interface ID will be the link state ID of the network LSA. SJ-20140504150128-018|2014-05-10 (R1.0) ZTE Proprietary and Confidential...
Page 74 ZXR10 ZSR V2 Configuration Guide (IPv6) To process the router LSA during SPF computation, two flag bits R and V6 are à added to the options field. The OSPF header contains an Example ID, thus allowing the operation of multiple OSPF protocol instances over a single link.

Multicast routing protocols use the RPF check mechanism during creation of multicast routing entries to ensure that multicast data can be transmitted through a correct path. This can also avoid generation of loops due to various reasons. 11-1 SJ-20140504150128-018|2014-05-10 (R1.0) ZTE Proprietary and Confidential...
