【正文】 路備份測試目標：通過tracert命令測試查看路由路徑的變化，檢測鏈路備份是否正常。為了驗證鏈路備份的可靠性，將R2 E/2與R6 E1/2端口OSPF 開銷值設置為1，測試pc2與pc1連通性。 。5 心得體會，懂得怎樣融合知識點到一個項目中；，然后就可以清晰的實現(xiàn)項目；:RIP、OSPF、鏈路備份、路由重發(fā)布、OSPF的接入認證。）7 附錄RT1配置腳本：Building configuration..Current configuration : 1197 bytes!version service timestamps debug datetime msecservice timestamps log datetime msecno service passwordencryption!hostname R1!bootstartmarkerbootendmarker!no aaa newmodelmemorysize iomem 5!ip cefno ip domain lookupip domain name !interface Ethernet1/0 ip address ip OSPF messagedigestkey 1 md5 cisco halfduplex!interface Ethernet1/1 ip address ip OSPF messagedigestkey 1 md5 cisco halfduplex!interface Ethernet1/2 ip address halfduplex!router OSPF 1 routerid logadjacencychanges area 0 authentication messagedigest area 2 authentication messagedigest timers lsa arrival 60 network area 0 network area 0 network area 2!no ip serverno ip secureserver！controlplaneline con 0 exectimeout 0 0 privilege level 15 logging synchronousline aux 0 exectimeout 0 0 privilege level 15 logging synchronousline vty 0 4 login！endRT2配置腳本：Building configuration...Current configuration : 1594 bytes!version service timestamps debug datetime msecservice timestamps log datetime msecno service passwordencryption!hostname R2!bootstartmarkerbootendmarker!no aaa newmodelmemorysize iomem 5!ip cefno ip domain lookupip domain name !interface Ethernet1/0 ip address ip OSPF messagedigestkey 1 md5 cisco halfduplex!interface Ethernet1/1 ip address halfduplex!interface Ethernet1/2 ip address ip OSPF messagedigestkey 1 md5 cisco ip OSPF cost 1 halfduplex!interface Ethernet1/3 ip address ip OSPF messagedigestkey 1 md5 cisco halfduplex!router OSPF 1 routerid logadjacencychanges area 0 authentication messagedigest area 1 authentication messagedigest area 1 STUB timers lsa arrival 60 network area 0 network area 0 network area 1 network area 1!no ip serverno ip secureserver!controlplane!line con 0 exectimeout 0 0 privilege level 15 logging synchronousline aux 0 exectimeout 0 0 privilege level 15 logging synchronousline vty 0 4 login!EndRT3配置腳本：R3show runningconfig Building configuration...Current configuration : 1516 bytes!version service timestamps debug datetime msecservice timestamps log datetime msecno service passwordencryption!hostname R3!bootstartmarkerbootendmarker!no aaa newmodelmemorysize iomem 5!ip cefno ip domain lookupip domain name !!interface Ethernet1/0 ip address ip OSPF messagedigestkey 1 md5 cisco halfduplex!interface Ethernet1/1 ip address ip OSPF messagedigestkey 1 md5 cisco halfduplex!interface Ethernet1/2 ip address ip summaryaddress RIP halfduplex!router OSPF 1 routerid logadjacencychanges area 2 authentication messagedigest timers lsa arrival 60 redistribute RIP metric 10 network area 2 network area 2! router RIP version 2 redistribute OSPF 1 metric 5 network !no ip serverno ip secureserver!controlplane!line con 0 exectimeout 0 0 privilege level 15 logging synchronousline aux 0 exectimeout 0 0 privilege level 15 logging synchronousline vty 0 4 login!EndRT4配置腳本：R4show runningconfig Building configuration...Current configuration : 1100 bytesversion service timestamps debug datetime msecservice timestamps log datetime msecno service passwordencryption!hostname R4!bootstartmarkerbootendmarker!no aaa newmodelmemorysize iomem 5!ip cefno ip domain lookupip domain name !interface Ethernet1/0 ip address ip OSPF messagedigestkey 1 md5 cisco halfduplex!interface Ethernet1/1 ip address ip OSPF messagedigestkey 1 md5 cisco halfduplex!interface Ethernet1/2 no ip address shutdown halfduplex!interface Ethernet1/3 no ip address shutdown halfduplex!router OSPF 1 logadjacencychanges area 2 authentication messagedigest timers lsa arrival 60 network area 2 network area 2!no ip serverno ip secureserver!controlplane!line con 0 exectimeout 0 0 privilege level 15 logging synchronousline aux 0 exectimeout 0 0 privilege level 15
