HL-010备份中心原理及配置ISSUE5.1日期：掌握备份中心的基本功能在H3C路由器上配置备份中心功能课程目标学习完本课程，您应该能够：什么是备份中心备份中心基本配置配置实例目录什么是备份中心？H3C路由器中管理备份功能的模块运用备份中心可以提高网络的可靠性、可用性运用备份中心为路由器接口提供备份QuidwayQuidwayModemModemPSTN备份中心的功能主接口被其他接口备份任意一个物理口或子接口均可作为主接口

逻辑接口（包括Virtual-Template接口，Dialer接口，但除MFR和逻辑通道以外）备份接口备份其他接口物理接口，逻辑接口，逻辑通道任何接口物理接口，子接口，逻辑接口，逻辑通道什么是备份中心备份中心基本配置配置实例目录备份中心配置任务进入主接口视图指定主接口使用的备用接口及其优先级设置主备接口切换的延时配置备份负载分担进入主接口配置视图主接口是一物理接口interfaceinterface-typeinterface-number主接口是一个逻辑接口如Dialer口

interface

Dialerinterface-number注：主接口最好是链路层协议可以down掉的，比如ppp，hdlc等；因为备份以太口的意义不大，只要物理口up，链路层永远up，备份链路是无法启动的。设定备份接口及优先级若备份接口是物理接口，在主接口视图下指定备份接口

interface-num[priority]

配置备份负载分担负载分担：当流量超过一定限度时启动备份接口在主接口视图下配置：

standbythresholdThreshold1Threshold2其中Threshold1：流量上限百分比（0-99），超过此上限时启动备份接口Threshold2：流量下限百分比（0-99），低于此下限时关闭备份接口什么是备份中心备份中心基本配置配置实例目录配置举例一组网需求：以太口0/0的IP地址:RouterA(130.1.1.1)RouterB(131.1.1.1)主接口：Serial1/0封装PPP备份接口:Serial1/1RouterARouterBModemModemTel:8810025IP10.110.0.1IP129.102.0.1IP10.110.0.2IP129.102.0.2Tel:8810026PPPPSTN配置举例(一)[RouterA-Ethernet0/0]ipaddress130.1.1.1255.255.255.0[RouterA-Ethernet0/0]interfaceserial1/0[RouterA-Serial1/0]ipaddress129.102.0.1255.255.0.0[RouterA-Serial1/0]standbyinterfaceserial1/1[RouterA-Serial1/0]interfaceserial1/1[RouterA-Serial1/1]physical-modeasync[RouterA-Serial1/1]modem[RouterA-Serial1/1]ipaddress10.110.0.1255.255.0.0[RouterA-Serial1/1]dialerenable-circular[RouterA-Serial1/1]dialer-group1[RouterA-Serial1/1]dialerrouteip10.110.0.28810026[RouterA-Serial1/1]quit[RouterA]dialer-rule1ippermit[RouterA]iproute-static131.1.1.0255.255.255.0129.102.0.2[RouterA]iproute-static131.1.1.0255.255.255.010.110.0.2配置RouterA配置举例(一)[RouterB-Ethernet0/0]ipaddress131.1.1.1255.255.255.0[RouterB-Ethernet0/0]interfaceserial1/0[RouterB-Serial1/0]ipaddress129.102.0.2255.255.0.0[RouterB-Serial1/0]interfaceserial1/1[RouterB-Serial1/1]physical-modeasync[RouterB-Serial1/1]modem[RouterB-Serial1/1]ipaddress10.110.0.2255.255.0.0[RouterB-Serial1/1]dialerenable-circular[RouterB-Serial1/1]dialer-group1[RouterB-Serial1/1]dialerrouteip10.110.0.18810025[RouterB-Serial1/1]quit[RouterB]dialer-rule1ippermit[RouterB]iproute-static130.1.1.0255.255.255.0129.102.0.1[RouterB]iproute-static130.1.1.0255.255.255.010.110.0.1配置RouterB配置举例二组网需求：以太口E0/0的IP地址:RouterA(130.1.1.1)RouterB(131.1.1.1)主接口：Serial1/0封装PPP备份接口:Dialer0的逻辑通道10，互相切换时间为10秒IP10.110.0.1RouterARouterBModemModemTel:1000IP129.102.0.1IP10.110.0.2IP129.102.0.2Tel:2000PPPS1/0S1/0PSTN配置举例(二)[RouterA-Ethernet0/0]ipaddress130.1.1.1255.255.255.0[RouterA]interfacelogic-channel10[RouterA]interfaceDialer0[RouterA-Dialer0]ipaddress129.102.0.1255.255.255.0[RouterA-Dialer0]dialerenable-circular[RouterA-Dialer0]dialer-group1[RouterA-Dialer0]dialerrouteip129.102.0.22000logic-channel10[RouterA]interfaceSerial0/0[RouterA-Serial0/0]link-protocolppp[RouterA-Serial0/0]ipaddress10.110.0.1255.255.255.0[RouterA-Serial0/0]standbyinterfaceLogic-Channel10[RouterA]iproute-static131.1.1.0255.255.255.0129.102.0.2[RouterA]iproute-static131.1.1.0255.255.255.010.110.0.2配置RouterA:
