6、r5ntp-serviceunicast-peer3.0.1.32以上配置將Router4和Router5配置為對(duì)等體，Router5處于主動(dòng)對(duì)等體模式,Router4處于被動(dòng)對(duì)等體模式，由于Router5的層數(shù)為1，而Router4的層數(shù)為3，所以Router4向Router5同步。同步后觀測(cè)Router4的狀態(tài)為：Router4displayntp-servicestatusclockstatus:synchronized,stratum:2,referenceclockID:3.0.1.33nominalfreq:250.0000Hz,actualfreq:249.9992Hz,prec

10、置為從接口Ethernet0監(jiān)聽(tīng)廣播消息，而Router3從接口Ethernet0發(fā)送廣播消息包，由于Router1與Router3不在相同的網(wǎng)段，所以接收不到Router3發(fā)出的廣播包，而Router4接收到Router3發(fā)出的廣播包后與其同步。同步后觀測(cè)Router4的狀態(tài)為：Router4displayntp-servicestatusclockstatus:synchronized,stratum:3,referenceclockID:3.0.1.31nominalfreq:250.0000Hz,actualfreq:249.9992Hz,precision:2*19offset:19

14、te門配置為從接口Ethernet0監(jiān)聽(tīng)組播消息,而Router3從接口Ethernet0發(fā)送組播消息包，由于Route門與Router3不在相同的網(wǎng)段,所以接口不到Router3發(fā)出的組播包,而Router4接收到Router3發(fā)出的組播包后與其同步。同步后觀測(cè)Router4的狀態(tài)為：Router4displayntp-servicestatusclockstatus:synchronized,stratum:3,referenceclockID:3.0.1.31nominalfreq:250.0000Hz,actualfreq:249.9992Hz,precision:2*19offset
