利用distribute-list列表过滤路由

利用distribute-list列表过滤路由
利用distribute-list列表过滤路由 实验目的：        1：熟练配置路由重分发        2：利用distribute-list过滤相应的路由1：具体配置R1!EnableConf thostname Londonno ip domain-lookline cons 0no exec-timelogg sync!interface Loopback0ip address 172.16.1.1 255.255.255.0!interface Loopback1ip address 172.16.2.1 255.255.255.0!interface Loopback2ip address 172.16.3.1 255.255.255.0!interface Loopback3ip address 172.16.4.1 255.255.255.0!interface Loopback4ip address 172.16.5.1 255.255.255.0!interface Loopback5ip address 172.16.6.1 255.255.255.0!interface Loopback6ip address 172.16.7.1 255.255.255.0!interface Loopback7ip address 172.16.8.1 255.255.255.0!Interface loopback 8Ip add 1.1.1.1 255.255.255.255!interface Serial1ip address 10.1.1.1 255.255.255.252no sh!router ospf 1router-id 1.1.1.1network 0.0.0.0 255.255.255.255 area 0!end按要求配置该路由器的各个接口，并启用ospf，最后把所有网络宣告进ospf中，且属于area0。R13!EnableConf thostname Florenceno ip domain-lookline cons 0no exec-timelogg sync!Int loo 0Ip add 2.2.2.2 255.255.255.255!interface Serial1ip address 10.1.1.2 255.255.255.252clockrate 64000no sh!         interface Serial0ip address 10.1.1.6 255.255.255.252clockrate 64000no sh!router eigrp 50no autonetwork 10.1.1.6 0.0.0.0redistribute ospf 1 metric 10000 100 255 1 1500(把ospf宣告进eigrp)distribute-list 12 out ospf 1（定义哪些路由会被过滤）auto-summary!router ospf 1router-id 2.2.2.2network 10.1.1.2 0.0.0.0 area 0redistribute eigrp 50 subnets（把eigrp重分发进ospf）distribute-list 11 out eigrp 50 (对向eigrp发送的路由做过滤)!access-list 11 permit 192.168.1.0 0.0.0.255（允许哪些路由被公布给eigrp）access-list 11 permit 192.168.3.0 0.0.0.255access-list 11 permit 192.168.5.0 0.0.0.255access-list 11 permit 192.168.7.0 0.0.0.255access-list 12 deny   172.16.2.0 0.0.0.255（阻止哪些路由被公布出去）access-list 12 deny   172.16.4.0 0.0.0.255access-list 12 deny   172.16.6.0 0.0.0.255access-list 12 deny   172.16.8.0 0.0.0.255access-list 12 permit any!End按要求配置该路由器的各个接口，并起用eigrp和ospf，把相应的网络宣告进ospf的area0和eigrp中，还分别在eigrp和ospf进程下用distribute-list过滤了默些路由，自己查看路由表和acl表，判断哪些路由被阻止，哪些被允许宣告出去。R3!EnableConf thostname Denverno ip domain-lookupline cons 0no exec-timelogg sync!interface Loopback0ip address 192.168.1.1 255.255.255.0!interface Loopback1ip address 192.168.2.1 255.255.255.0!interface Loopback2ip address 192.168.3.1 255.255.255.0!interface Loopback3ip address 192.168.4.1 255.255.255.0!interface Loopback4ip address 192.168.5.1 255.255.255.0interface Loopback5ip address 192.168.6.1 255.255.255.0!interface Loopback6ip address 192.168.7.1 255.255.255.0!interface Loopback7ip address 192.168.8.1 255.255.255.0!interface Serial1ip address 10.1.1.5 255.255.255.252no sh!router eigrp 50no  auto-summarynetwork 0.0.0.0!end按要求配置该路由器的各个接口，并起用eigrp，把所有的接口宣告进eigrp。1：仔细查看路由表规定的路由是否被过滤了2：思考acl如何只用1条命令，做到奇偶过滤。
