OSPF特殊区域及LSA详解 OSPF高级功能及实现1.什么是LSA？常见的有六种类型，分别是、、、、和类型代码描述用途查看路由器区域内产生，描述了路由器所有接口、链路和值。只能在本区域内泛洪。网络由产生，报文包括了其连接的所有的，其中包含自己的。网络汇总可以通知本区域内的路由器通往区域外的路由信息。默认路由也被通告。为目标网段的汇总也是由产生，但是它是一条主机，指向路由器外部由产生，告诉本自治区的路由器通往外部自治区的路径。外部由产生，几乎和通告是相同的，但外部通告仅仅在始发这个外部通告的非纯末梢区域内部进行泛洪。3.Type1:路由器LSA Router LSA每个路由器针对它所在的区域产生LSA1，描述区域内部不路由器直连的链路的信息（包括链路类型，Cost等）；LSA1只允许在本区域内洪泛，不允许跨越ABR；LSA中会标识路由器是否是ABR(B比特置位),ASBR（E比特置位）或者是Virtual-link（V比特置位）的端点的身份信息；Type=1Router ID = &192.168.30.10Number of &Links = 3Link 1 DescriptionLink 2 DescriptionLink 3 Description4.Type2:网络LSA Network LSA描述TransNet（包括Broadcast和NBMA网络）网络信息；由DR生成，描述其在该网络上连接的所有路由器以及网段掩码信息，以及这个MA所属的路由器；LSA类型2只在本区域Area内洪泛，丌允许跨越ABR；Network LSA ID是DR进行宣告的那个接口的IP地址Network LSA 中没有COST字段Type=2192.168.17.18Subnet Mask = 255.255.255.248Attached Router &= 192.168.30.20Attached Router &= 192.168.30.10Attached Router &= 192.168.30.305.类型LSA1和LSA2总结通过LSA1，LSA2在区域内洪泛,使区域内每个路由器的LSDB达到同步，计算生成标识为“O”的路由，解决区域内部的通信问题；6.Type3: 网络汇总LSA Network Summary LSA由ABR生成，实际上就是将区域内部的Type1 Type2的信息收集起来以路由子网的形式扩散出去, 这就是Summay LSA中Summay的含义（注意这里的summary不路由汇总没有关系）；Type 3 的链路状态ID是目的网络地址。如果―台ABR路由器在不它本身相连的区域内有多条路由可以到达目的地,那么它将只会始发单一的一条网络汇总LSA到骨干区域,而且这条网络汇总LSA是上述多条路由中代价最低的。ABR收到来自同区域其它ABR传来的Type 3 LSA后重新生成新的Type3 LSA（Advertising Router改为自己）然后继续在整个OSPF系统内扩散Type=3172.16.121.0Mask = 255.255.255.0Metric = 7917.Type4： ASBR Summary LSA ASBR Summary LSA由ABR生成，用于描述ABR能够到达的ASBR它的链路状态ID为目的ASBR的RID。Type=4192.168.30.12Mask = 0.0.0.0Metric = 648.Type5：自治系统外LSA AS External LSA Autonomous System External LSA由ASBR生成用于描述OSPF自治域系统外的目标网段信息链路状态ID是目的地址的IP网络号。外部路由通过重发布，引入OSPF路由域，相应信息(路由条目)由ASBR以LSA5的形式生成然后进入OSPF路由域；缺省情况下，LSA5生成路由用OE2表示，可强行指定为OE1；OE2 开销 =此路由的度量值默认为20，且在域内/外不累加，恒为20OE1 开销 =此路由的度量值默认为20，且在域外不累加，域内累加LSA5不允许进入特殊区域―― stub存根区& NSSA区；Type=510.83.10.0Mask = &255.255.255.0Metric = 10Forwarding &Address = 172.20.57.2549.Type7： NSSA中的外部LSA NSSA External LSA在域内有ASBR的情况下启用NSSA后，原ASBR的LSA5 将替换成LSA7 ，原有的ABR的LSA4和LSA5将替换成LSA7，原ABR也将替换成ASBR在NSSA(非完全存根区域)not-so-stubby area中ASBR针对外部网络产生类似于LSA5的LSA类型7,LSA类型7只能在NSSA区域中洪泛，到达NSSA区域ABR后，NSSA ABR将其转换成LSA类型5外部路由，传播到Area 0，从而传播到整个OSPF路由域生成路由缺省用ON2表示，也可指定为ON1；10.OSPF常用检查命令show ip route查看路由表信息（直连/学习）show ip route ospf只查看OSPF学习到的路由show ip protocol查看OSPF协议配置信息show ip ospf查看OSPF是如何配置的以及ABR的信息show ip ospf database查看LSDB内的所有LSA数据信息show ip ospf interface查看接口上OSPF配置的信息show ip ospf neighbor查看OSPF邻居和邻接的状态show ip ospf neighbor detail 查看OSPF邻居的详细信息（包括DR/BDR）debug ip ospf adj查看路由器“邻接”的整个过程debug ip ospf packet查看每个OSPF数据包的信息clear ip route清空路由表11.OSPF区域的类型与LSA的洪泛范围一个区域所设置的特性决定着它能接收的路由,OSPF将整个OSPF路由域划分为丌同的区域,目的是为减少丌必要的路由信息的传递，精简路由表。区域类型1&234&57骨干区域（区域0）允许允许允许不允许非骨干区域，非末梢区域允许允许允许不允许末梢区域允许允许不允许不允许完全末梢区域允许不允许*不允许不允许NSSA允许允许不允许允许ASBR会通过自己的LSA1中有标识着自己是ASBR的字段，当ASBR同区域的ABR收到后，会为自己所在的除已知ASBR信息区域外的所有区域生成LSA4，用来通告ASBR信息。 ABR的LSA1中亦有一个标识自己是ABR的字段。所有LSA1、LSA2、LSA3信息在Area0的ABR路由器上汇总成新的LSA3，再通告给其他Area。12.路由重分发将其他协议或静态等路由通过ASBR路由器通告到OSPF中去。命令：redistribute配置路由路由重分发R5(config-router)#redistribute protocol [metricmetric-value] [metric-type type-value] [subnets]protocol：进行路由重发的源路由协议，如：bgp、eqp、isis、ospf [process-id（进程）]、staic（静态）、connect（直连）、ripmetric：指定路由的度量值metric-type：重分发的路由类型，1或2，即E1和E2subnets：与其子网一起宣告，即关闭子网汇总RIP重分发至OSPF（度量值默认为20，类型默认为E2） &R1(config-router)#redistribute rip subnets将OSPF重分发至到RIP &R1(config-router)#redistribute ospf 110 metric 10 & 110：ospf协议进程ID & 10：默认度量值静态路由重分发 &R5(config-router)#redistribute static subnets默认路由重分发 &R5(config-router)#default-information originate [always]always：直接重分发路由，ASBR可以不配置默认路由13.末梢区域和完全末梢区域拥有以下4个特点：只有一个默认路由作为其区域的出口区域不能作为虚链路的穿越区域 & Stub区域里无自治系统边界路由器ASBR不是骨干区域Area 0末梢区域（Stub Area）没有LSA4、LSA5、LSA7通告，将重分发的路由信息汇聚成一条默认路由配置命令 &R1(config-router)#area area-id stub完全末梢区域（Totally Stubby Area）除一条LSA3的默认路由通告外，没有LSA3、LSA4、LSA5、LSA7通告，将重分发的路由信息和LSA3路由信息汇聚成一条默认路由配置命令 & R1(config-router)#areaarea-id stub no-summary（在整个区域的所有路由器中都要配置）非纯末梢区域（NSSA）配置了NSSA区域后，ASBR所在OSPF区域内的LSA5通告信息被LSA7替代了LSA5，此区域本来的ABR将LSA7转换成了LSA5，此ABR兼任了ASBR。no-summary 将其他域内的路由信息（LSA3）汇总成一条默认路由。配置NSSA区域 &R1(config-router)#area area-id &nssa &[no-summary]14.路由汇总外部汇总 &R1(config-router)#area 2 range ip-address mask内部汇总 &R4(config-router)#summary-address ip-address maskBy:孤狼本文出自 “” 博客，请务必保留此出处

LINK ID出现在OSPF 的LSA中的，link id 即连接ID，在不同种类的LSA中link id 所描述的对象不同，或是router-id，或是网络地址。
OSPF的有以下几种LSA:
Type-1 lsa (router isa)
Type-2 lsa (network lsa)
Type-3 lsa (network summary lsa)
Type-4 lsa (asbr summary lsa)
Type-5 lsa (as external lsa)
Type-7 lsa (nssa external lsa)
LINK又分为4类:
& && && && && && && && && &
Point to Point&&link& & 描述链路是P to P
& && && && && && && && && &&&Stub network&&link& &&&描述网段信息
& && && && && &Transmit&&network&&link& &&&描述DR.BDR
& && && && && && && && && &&& Virtual-link& &link& && &&&描述虚链接

Link ID只在1类LSA存在，你刚开始说的“不同种类的LSA中Link ID的描述对象也不同”指的是Link State ID

你说的这个是1类LSA报文里面的link type吧，不是link id

OSPF特殊区域及LSA详解 OSPF高级功能及实现1.什么是LSA？常见的有六种类型，分别是、、、、和类型代码描述用途查看路由器区域内产生，描述了路由器所有接口、链路和值。只能在本区域内泛洪。网络由产生，报文包括了其连接的所有的，其中包含自己的。网络汇总可以通知本区域内的路由器通往区域外的路由信息。默认路由也被通告。为目标网段的汇总也是由产生，但是它是一条主机，指向路由器外部由产生，告诉本自治区的路由器通往外部自治区的路径。外部由产生，几乎和通告是相同的，但外部通告仅仅在始发这个外部通告的非纯末梢区域内部进行泛洪。3.Type1:路由器LSA Router LSA每个路由器针对它所在的区域产生LSA1，描述区域内部不路由器直连的链路的信息（包括链路类型，Cost等）；LSA1只允许在本区域内洪泛，不允许跨越ABR；LSA中会标识路由器是否是ABR(B比特置位),ASBR（E比特置位）或者是Virtual-link（V比特置位）的端点的身份信息；Type=1Router ID = &192.168.30.10Number of &Links = 3Link 1 DescriptionLink 2 DescriptionLink 3 Description4.Type2:网络LSA Network LSA描述TransNet（包括Broadcast和NBMA网络）网络信息；由DR生成，描述其在该网络上连接的所有路由器以及网段掩码信息，以及这个MA所属的路由器；LSA类型2只在本区域Area内洪泛，丌允许跨越ABR；Network LSA ID是DR进行宣告的那个接口的IP地址Network LSA 中没有COST字段Type=2192.168.17.18Subnet Mask = 255.255.255.248Attached Router &= 192.168.30.20Attached Router &= 192.168.30.10Attached Router &= 192.168.30.305.类型LSA1和LSA2总结通过LSA1，LSA2在区域内洪泛,使区域内每个路由器的LSDB达到同步，计算生成标识为“O”的路由，解决区域内部的通信问题；6.Type3: 网络汇总LSA Network Summary LSA由ABR生成，实际上就是将区域内部的Type1 Type2的信息收集起来以路由子网的形式扩散出去, 这就是Summay LSA中Summay的含义（注意这里的summary不路由汇总没有关系）；Type 3 的链路状态ID是目的网络地址。如果―台ABR路由器在不它本身相连的区域内有多条路由可以到达目的地,那么它将只会始发单一的一条网络汇总LSA到骨干区域,而且这条网络汇总LSA是上述多条路由中代价最低的。ABR收到来自同区域其它ABR传来的Type 3 LSA后重新生成新的Type3 LSA（Advertising Router改为自己）然后继续在整个OSPF系统内扩散Type=3172.16.121.0Mask = 255.255.255.0Metric = 7917.Type4： ASBR Summary LSA ASBR Summary LSA由ABR生成，用于描述ABR能够到达的ASBR它的链路状态ID为目的ASBR的RID。Type=4192.168.30.12Mask = 0.0.0.0Metric = 648.Type5：自治系统外LSA AS External LSA Autonomous System External LSA由ASBR生成用于描述OSPF自治域系统外的目标网段信息链路状态ID是目的地址的IP网络号。外部路由通过重发布，引入OSPF路由域，相应信息(路由条目)由ASBR以LSA5的形式生成然后进入OSPF路由域；缺省情况下，LSA5生成路由用OE2表示，可强行指定为OE1；OE2 开销 =此路由的度量值默认为20，且在域内/外不累加，恒为20OE1 开销 =此路由的度量值默认为20，且在域外不累加，域内累加LSA5不允许进入特殊区域―― stub存根区& NSSA区；Type=510.83.10.0Mask = &255.255.255.0Metric = 10Forwarding &Address = 172.20.57.2549.Type7： NSSA中的外部LSA NSSA External LSA在域内有ASBR的情况下启用NSSA后，原ASBR的LSA5 将替换成LSA7 ，原有的ABR的LSA4和LSA5将替换成LSA7，原ABR也将替换成ASBR在NSSA(非完全存根区域)not-so-stubby area中ASBR针对外部网络产生类似于LSA5的LSA类型7,LSA类型7只能在NSSA区域中洪泛，到达NSSA区域ABR后，NSSA ABR将其转换成LSA类型5外部路由，传播到Area 0，从而传播到整个OSPF路由域生成路由缺省用ON2表示，也可指定为ON1；10.OSPF常用检查命令show ip route查看路由表信息（直连/学习）show ip route ospf只查看OSPF学习到的路由show ip protocol查看OSPF协议配置信息show ip ospf查看OSPF是如何配置的以及ABR的信息show ip ospf database查看LSDB内的所有LSA数据信息show ip ospf interface查看接口上OSPF配置的信息show ip ospf neighbor查看OSPF邻居和邻接的状态show ip ospf neighbor detail 查看OSPF邻居的详细信息（包括DR/BDR）debug ip ospf adj查看路由器“邻接”的整个过程debug ip ospf packet查看每个OSPF数据包的信息clear ip route清空路由表11.OSPF区域的类型与LSA的洪泛范围一个区域所设置的特性决定着它能接收的路由,OSPF将整个OSPF路由域划分为丌同的区域,目的是为减少丌必要的路由信息的传递，精简路由表。区域类型1&234&57骨干区域（区域0）允许允许允许不允许非骨干区域，非末梢区域允许允许允许不允许末梢区域允许允许不允许不允许完全末梢区域允许不允许*不允许不允许NSSA允许允许不允许允许ASBR会通过自己的LSA1中有标识着自己是ASBR的字段，当ASBR同区域的ABR收到后，会为自己所在的除已知ASBR信息区域外的所有区域生成LSA4，用来通告ASBR信息。 ABR的LSA1中亦有一个标识自己是ABR的字段。所有LSA1、LSA2、LSA3信息在Area0的ABR路由器上汇总成新的LSA3，再通告给其他Area。12.路由重分发将其他协议或静态等路由通过ASBR路由器通告到OSPF中去。命令：redistribute配置路由路由重分发R5(config-router)#redistribute protocol [metricmetric-value] [metric-type type-value] [subnets]protocol：进行路由重发的源路由协议，如：bgp、eqp、isis、ospf [process-id（进程）]、staic（静态）、connect（直连）、ripmetric：指定路由的度量值metric-type：重分发的路由类型，1或2，即E1和E2subnets：与其子网一起宣告，即关闭子网汇总RIP重分发至OSPF（度量值默认为20，类型默认为E2） &R1(config-router)#redistribute rip subnets将OSPF重分发至到RIP &R1(config-router)#redistribute ospf 110 metric 10 & 110：ospf协议进程ID & 10：默认度量值静态路由重分发 &R5(config-router)#redistribute static subnets默认路由重分发 &R5(config-router)#default-information originate [always]always：直接重分发路由，ASBR可以不配置默认路由13.末梢区域和完全末梢区域拥有以下4个特点：只有一个默认路由作为其区域的出口区域不能作为虚链路的穿越区域 & Stub区域里无自治系统边界路由器ASBR不是骨干区域Area 0末梢区域（Stub Area）没有LSA4、LSA5、LSA7通告，将重分发的路由信息汇聚成一条默认路由配置命令 &R1(config-router)#area area-id stub完全末梢区域（Totally Stubby Area）除一条LSA3的默认路由通告外，没有LSA3、LSA4、LSA5、LSA7通告，将重分发的路由信息和LSA3路由信息汇聚成一条默认路由配置命令 & R1(config-router)#areaarea-id stub no-summary（在整个区域的所有路由器中都要配置）非纯末梢区域（NSSA）配置了NSSA区域后，ASBR所在OSPF区域内的LSA5通告信息被LSA7替代了LSA5，此区域本来的ABR将LSA7转换成了LSA5，此ABR兼任了ASBR。no-summary 将其他域内的路由信息（LSA3）汇总成一条默认路由。配置NSSA区域 &R1(config-router)#area area-id &nssa &[no-summary]14.路由汇总外部汇总 &R1(config-router)#area 2 range ip-address mask内部汇总 &R4(config-router)#summary-address ip-address maskBy:孤狼本文出自 “” 博客，请务必保留此出处

LINK ID出现在OSPF 的LSA中的，link id 即连接ID，在不同种类的LSA中link id 所描述的对象不同，或是router-id，或是网络地址。
OSPF的有以下几种LSA:
Type-1 lsa (router isa)
Type-2 lsa (network lsa)
Type-3 lsa (network summary lsa)
Type-4 lsa (asbr summary lsa)
Type-5 lsa (as external lsa)
Type-7 lsa (nssa external lsa)
LINK又分为4类:
& && && && && && && && && &
Point to Point&&link& & 描述链路是P to P
& && && && && && && && && &&&Stub network&&link& &&&描述网段信息
& && && && && &Transmit&&network&&link& &&&描述DR.BDR
& && && && && && && && && &&& Virtual-link& &link& && &&&描述虚链接

Link ID只在1类LSA存在，你刚开始说的“不同种类的LSA中Link ID的描述对象也不同”指的是Link State ID

你说的这个是1类LSA报文里面的link type吧，不是link id
