• 【H3C设备组网配置】第二版


    在这里插入图片描述

    实验要求:

    1、服务器组双链路 上联核心,调高数据可靠性
    2、配置vlan,减小广播域范围
    3、所有网关都设在核心上,部分ip需自动获取
    4、业务端口,配置边缘端口,减小频繁up down对网络的影响
    5、配置相关路由,使的用户可以访问外网及新校区
    6、广域网出口做主备,线路正常走联通
    7、所有设备可以被Telnet ,管理网段255.x,vlan999
    8、vlan30 用户不能访问200.4

    服务器sw网桥聚合

    思路

    1、起网桥聚合
    2、聚合口为trunk

    2、配置vlan,减小广播域范围

    思路

    1、目标 vlan 10 vlan 20 vlan 30 vlan 40 vlan 80 vlan 200
    疑问:服务器支路和pc9支路,如果按需开启vlan200 和999  会怎样 ?
    答:就是要按需开启,没有必要开启其他的
    2、用dis vlan b

    4 STP 协议树

    核心为根网桥 优先级改成0

    [sw1]stp priority 0

    业务口配置边缘口

    使得pc up down不影响网络

    5、配置ospf 联通新校区

    思路

    1、核心sw1 起ospf ,宣告网段

    [sw1]ospf 1
    [sw1-ospf-1]area 1
    [sw1-ospf-1-area-0.0.0.1]network 192.168.10.0 0.0.0.255

    验证 用新校区路由器及PC_13可以ping通 服务器200.4

    Ping 192.168.200.4 (192.168.200.4): 56 data bytes, press CTRL+C to break

    6、访问外网

    1) 核心 sw1 改02口为route模式,并设置地址

    [sw1]int g1/0/2
    [sw1-GigabitEthernet1/0/2]port link-mode route
    [sw1-GigabitEthernet1/0/2]ip address 192.168.100.1 24
    
    • 1
    • 2
    • 3

    2) R-外网 设各口IP地址

    [R-外网]int g0/2
    [R-外网-GigabitEthernet0/2]ip a 192.168.100.2 24
    
    [R-外网-GigabitEthernet0/2]int g0/0
    [R-外网-GigabitEthernet0/0]ip a 12.1.1.1 24
    [R-外网-GigabitEthernet0/0]int g0/1
    [R-外网-GigabitEthernet0/1]ip a 13.1.1.1 24
    
    [R-外网-GigabitEthernet0/1]int s1/0
    [R-外网-Serial1/0]ip ad 14.1.1.1 24

    • 3
    • 4
    • 5
    • 6
    • 7
    • 8
    • 9
    • 10

    至此 PC_可以访问到12.1.1.1 但到不了 12.1.1.2 更到不了 6.6.6.6
    在这里插入图片描述

    <H3C>ping 192.168.80.13
    Ping 192.168.80.13 (192.168.80.13): 56 data bytes, press CTRL_C to break

    应该配置 直连路由了吧

    3) 核心sw1 设置默认路由,下一条100.2

    [sw1]ip route-static 0.0.0.0 0 192.168.100.2
    
    • 1

    在这里插入图片描述

    4) R-外网设置默认路由 ,吓一跳 12.1.1.2

    [R-外网]ip route-static 0.0.0.0 0 12.1.1.2
    
    • 1

    在这里插入图片描述

    5) R_联通 设置ip

    [R-联通]int g0/0
    [R-联通-GigabitEthernet0/0]ip address 12.1.1.2 24
    
    [R-联通]int LoopBack 1
    [R-联通-LoopBack1]ip address 6.6.6.6 24
    
    • 1
    • 2
    • 3
    • 4
    • 5

    至此连不通 6 6 6 6,应起acl

    [H3C]PING 6.6.6.6
    Ping 6.6.6.6 (6.6.6.6): 56 data bytes, press CTRL_C to break
    Request time out
    Request time out
    
    • 1
    • 2
    • 3
    • 4

    6) R_外网 起acl NAT地址转换

    [R-外网]acl basic 2000
    [R-外网-acl-ipv4-basic-2000]rule permit source 192.168.0.0 0.0.255.255 
    # 规则:允许192.168.0.0,通过无条件通过
    [R-外网-acl-ipv4-basic-2000]int g0/0
    [R-外网-GigabitEthernet0/0]nat outbound 2000
    # 0/0端口 ,调用2000规则
    
    • 1
    • 2
    • 3
    • 4
    • 5
    • 6

    7) 验证

    验证 可以 ping 6.6.6.6

    PING 6.6.6.6
    Ping 6.6.6.6 (6.6.6.6): 56 data bytes, press CTRL_C to break
    56 bytes from 6.6.6.6: icmp_seq=0 ttl=253 time=1.000 ms
    56 bytes from 6.6.6.6: icmp_seq=1 ttl=253 time=2.000 ms

    7、外网双线备份 ,联通为主,移动为副 ,自动切换

    1) R_外网 设路由 设优先级

    ip route-static 0.0.0.0 0 13.1.1.2 preference 70
    
    • 1

    2) R_移动 设置ip

    [R_移动]int LoopBack 3
    [R_移动-LoopBack3]ip a 7.7.7.7 24
    
    [R_移动-LoopBack3]int g0/0

    2) 通用代码 复制后 在每台设备上粘贴

    telnet serv en
    local-user abc class manage
    
    pas sim 123
    service-type telnet
    authorization-attribute user-role network-admin

    3)设置管理vlan 999和255.x的可以telnet

    核心交换机和接入交换机以及路由器 , 要可被Telnet ,就必须有地址(虚接口),
    故要设置管理vlan999.并给他一个255.x的地址
    使得  所有pc都可以访问各交换机和路由器
    
    • 1
    • 2
    • 3

    ① 核心sw 起管理vlan999 +ip

    [sw1-luser-manage-abc]int vlan 999
    [sw1-Vlan-interface999]ip address 192.168.255.1 24
    
    • 1
    • 2

    ②汇聚和接入交换机都要起管理vlan和管理地址

    int vlan 999
    ip add 192.168.255.x 24
    
    • 1
    • 2

    ③除主核心外 ,其他设备还要配置缺省路由 【不懂】

    [sw14]ip route-static 0.0.0.0 0 192.168.255.1;用于管理流量的回包
    
    • 1

    总结以下,除了核心交换机,都应该这么设置

    [sw-汇聚]vlan 999
    [sw-汇聚-vlan999]int vlan 999
    [sw-汇聚-Vlan-interface999]ip a 192.168.255.2 24
    [sw-汇聚-Vlan-interface999]qu
    [sw-汇聚]ip rou 0.0.0.0 0 192.168.255.1
    # c默认路由的目的是为了管理流量回包,要不pc访问不了

    检验排查

    [sw-接入]dis vlan
     Total VLANs: 3
     The VLANs include:
     1(default), 10, 999

    9、vlan30 用户不能访问200.5 ACL NAT 是packet-filer

    核心sw 设置高级阻断规则 acl

    [sw1]acl advanced 3000
    [sw1-acl-ipv4-adv-3000]rule deny ip source 192.168.30.0 0.0.0.255 destination 19
    2.168.200.5 0.0.0.0
    # 0.0.0.255? 是否合适
    [sw1-acl-ipv4-adv-3000]qu
    [sw1]int vlan 30
    # 要设置  vlan
    [sw1-Vlan-interface30]packet-filter 3000 inbound
    # 不是nat  是packet-filer

    结果很 ok 一切合乎设计要求

    另 实验 如果 192.168.200.5 0.0.0.0.0 改成 0.0.0.255
    [sw1-acl-ipv4-adv-3000]rule deny ip source 192.168.30.0 0.0.0.255 destination 19
    2.168.200.5 0.0.0.0

    [sw1-acl-ipv4-adv-3000]rule deny ip source 192.168.30.0 0.0.0.255 destination 19

    #【结果】 0.0.0.255? 是否合适 255 就使得200段的所有ip都不能ping通
