例如:ABR ASBR 都算是骨干区域路由器。 Routing updates and topology information are passed only between adjacent routers. 路由更新和拓扑信息只在建立邻接关系的路由器之间传递。 Forming OSPF adjacencies on point-to-point WAN links. 在点到点的WAN链路上,形成ospf 邻接关系。 Forming OSPF adjacencies on...
ASBR-summary-LSAs are generated by an ABR and advertised to all related areas except the area to which the ASBR belongs. AS-external-LSA (Type 5) Describes routes to a destination outside the AS. AS-external-LSAs are generated by an ASBR and advertised to all areas except stub areas ...
Backbone area: connects to all other OSPF areas and transmits inter-area routes. The backbone area is represented by area 0. Routes between non-backbone areas must be forwarded through the backbone area. The backbone area must have all its devices connected. All non-backbone areas must have ...
Area- areas are used to establish a hierarchical network. ABR- Area Border Router, router connected to multiple areas.ABRsare responsible forsummarizationandupdate suppressionbetween connected areas. ASBR- Autonomous System Boundary Router, router connected to an external network (in a different AS). ...
OSPF Areas Link-state routing requires a hierarchical network structure. 链路状态的路由协议 需要一个层次化的网络结构 This two-level hierarchy consists of the following: 这种两层的层次架构包括下面的: Transit area (backbone or area 0) 穿越区域,或者说传输区域, 又称为:骨干区域。 在多区域的ospf中,...
for packets to travel from one node to another. One of the key advantages of OSPF is its ability to support large networks with hundreds or even thousands of routers. OSPF uses a hierarchical structure with areas, which helps to reduce the complexity and overhead of routing information ...
Indicates routes between areas. Type 1 external route As Type 1 external routes offer higher reliability than Type 2 external routes, their costs are approximately the same as those of AS internal routes and are comparable with the costs of routes generated by OSPF. ...
Can subdivide the entire OSPF routing domain into smaller regions known as areas Can summarize routing information between areas to cut down on the size of the LSDB and the routing tables Each area has it's own LSDB Makes use of a two level hierarchy creating a simple hub and spoke topology...
OSPF is a link-state, hierarchical Interior Gateway Protocol (IGP) for network routing. This topic collection describes i5/OS support for OSPF configuration, authentication methods, point-to- point links, packet types and splitting an OSPF autonomous system (AS) into areas. It also includes three...
