IP 汇总(IP Summarization)是一种网络地址聚合技术,它可以将多个路由器的路由表归并成一个更大的路由表,从而减少路由表的数量和大小。IP 汇总技术可以将多个路由器的路由表归并成一个更大的路由表,这个更大的路由表可以用来代替原来的多个路由表,从而简化路由器的管理。 使用IP 汇总技术可以减少路由器的负担、减少...
Summarization configuration is considered only in the case of intra-area routes. Such route aggregation, even if achieved, causes more LSAs to be advertised to the backbone area, making the network unstable.Why Are the Routes with Smaller Costs Passing Through the Backbone Area Not Preferred?
Before configuring ABR route summarization, you have completed the following task: Configure basic OSPFv3 functions. Procedure Enter the system view. system-view Enter the OSPFv3 view. ospfv3 [ process-id ] Enter the OSPFv3 area view. area area-id Configure the ABR to summarize intra-area OSP...
(a) MAC address: 类似身份证号码 扁平地址结构 可以在一个LAN内移动。 (b) IP address: 类似邮政编码 层次地址结构 地址依赖于所在的IP 子网。 48 bit MAC 地址,固定于NIC ROM,有时软件可修改。(48个bit,可以用十六进制表示) MAC地址对计算机进行标识 00-01-2G-0A-AD-01是一个正确的MAC地址。(错) 2...
These logical boundaries facilitated by summarization are much easier to establish in IPv6. And because renumbering and resubnetting to support changes in interface host counts are no longer necessary, such logical boundaries are also much easier to maintain over time. ...

Summarization at area/domain boundary provides massive scaling advantage. No routing extension is required, a simple prefix advertisement suffices. Seamless Deployment: A uSID may be used as a SID (the carrier holds a single uSID). The...
