Abstract
摘 要
This document describes the modifications to OSPF to support version
6 of the Internet Protocol (IPv6). The fundamental mechanisms of
OSPF (flooding, Designated Router (DR) election, area support, Short
Path First (SPF) calculations, etc.) remain unchanged. However, some
changes have been necessary, either due to changes in protocol
semantics between IPv4 and IPv6, or simply to handle the increased
address size of IPv6. These modifications will necessitate
incrementing the protocol version from version 2 to version 3. OSPF
for IPv6 is also referred to as OSPF version 3 (OSPFv3).
本文档描述了OSPF为了支持版本6的网际互连协议(IPv6)而所做的修改。OSPF的基本
机制(泛洪、DR选举、区域支持、SPF计算„„)保持不变。但是,从IPv4到IPv6字面上
的变化以及单单随之产生的海量IP地址就迫使让我们必须对OSPF做一些改进。改进后的
OSPF的版本号就从2升到3了。适用于IPv6的OSPF也被称为OSPFv3.
