OSPF uses the cost as the route metric. Each OSPF-enabled interface has a cost value. The cost of an OSPF interface is calculated as follows: Cost = Reference bandwidth/Interface bandwidth. The default reference bandwidth is 100 Mbit/s. ...
OSPF uses the cost as the route metric. Each OSPF-enabled interface has a cost value. The formula used to calculate the cost is: Cost = 100M/Interface bandwidth. 100 Mbit/s is the OSPF reference bandwidth. The cost of an OSPF route is the sum of the cost values of all incoming inter...

Now clearly if we have a 1Gb interface, then that has more bandwidth than a 100Mb interface so we change the costs to reflect this, that is we increase the cost of a 100Mb interface and a 10Mb interface so the 1Gb cost reflects that it is a higher bandwidth. OSPF was designed with ...
aWhat is the OSPF default frequency,in seconds,at which a cisco router sends hello packets on a multiaccess network 什么是OSPF缺省频率,在几秒钟内, cisco路由器在一个多通道网络送你好小包 [translate] 英语翻译 日语翻译 韩语翻译 德语翻译 法语翻译 俄语翻译 阿拉伯语翻译 西班牙语翻译 葡萄牙语翻译 ...
The OSPF metric is calculated as the ref-bw value divided by the bandwidth value.The default ref-bw is 10^8bps.Cisco provides the command auto-cost reference-bandwidth, which allows the default reference bandwidth to be chan...

Once connected, routers regularly resend “Hello” packets to keep the connection alive. If no “Hello” packet is received for a configurable period called the dead interval, it will assume the link has gone down. Routing Metrics In OSPF, each connection is given a “path cost” metric. Th...
