淘宝 网站开发 退货,彩票走势图网站建设,用c 做网站在Linux上,wordpress加置顶功能需要完善
一、实验拓扑 二、实验需求 1、R2-7每台路由器均存在一个环回接口用于建立邻居#xff0c;同时还存在一个环回来代表连接用户的接口;最终这些连接用户的接口网络需要可以和R1/8的环回通讯 2、AS2网段地址172.16.0.0/16 减路由条目数量
三、实验步骤
首先配置IP

一、实验拓扑 二、实验需求 1、R2-7每台路由器均存在一个环回接口用于建立邻居同时还存在一个环回来代表连接用户的接口;最终这些连接用户的接口网络需要可以和R1/8的环回通讯 2、AS2网段地址172.16.0.0/16 减路由条目数量
三、实验步骤
首先配置IP
R1配置 [r1]int g0/0/0 [r1-GigabitEthernet0/0/0]ip address 12.1.1.1 24 [r1-GigabitEthernet0/0/0]int l 0 [r1-LoopBack0]ip ad 1.1.1.1 24 [r1-LoopBack0]int l 1 [r1-LoopBack1]ip address 132.1.1.1 32 R2配置 [r2]int g0/0/0 [r2-GigabitEthernet0/0/0]ip address 12.1.1.2 24 [r2-GigabitEthernet0/0/0]int l 0 [r2-LoopBack0]ip address 172.16.1.1 24 [r2-LoopBack0]int l1 [r2-LoopBack1]ip address 132.1.1.2 32 [r2]int g0/0/1 [r2-GigabitEthernet0/0/1]ip address 172.16.0.1 30 [r2-GigabitEthernet0/0/1]int g0/0/02 [r2-GigabitEthernet0/0/2]ip address 172.16.0.21 30 注意一会要在AS2中配置ospf所以要修改环回0的的接口类型 [r2-LoopBack0]ospf network-type broadcast R3配置 [r3]int g0/0/0 [r3-GigabitEthernet0/0/0]ip address 172.16.0.2 30 [r3-GigabitEthernet0/0/0]int g0/0/01 [r3-GigabitEthernet0/0/1]ip address 172.16.0.5 30 [r3]int l 0 [r3-LoopBack0]ip address 172.16.2.1 24 [r3-LoopBack0]ospf network-type broadcast [r3-LoopBack1]ip address 132.1.1.3 32 R4配置 [Huawei]int g0/0/0 [Huawei-GigabitEthernet0/0/0]ip address 172.16.0.6 30 [Huawei-GigabitEthernet0/0/0]int g0/0/1 [Huawei-GigabitEthernet0/0/1]ip address 172.16.0.9 30 [Huawei-GigabitEthernet0/0/1]int l 0 [Huawei-LoopBack0]ip address 172.16.3.1 24 [Huawei-LoopBack0]ospf network-type broadcast [Huawei-LoopBack0]int l1 [Huawei-LoopBack1]ip address 132.1.1.4 32 R7配置 [r7] int g0/0/0 [r7-GigabitEthernet0/0/0]ip address 172.16.0.10 30 [r7-GigabitEthernet0/0/0]int g0/0/1 [r7-GigabitEthernet0/0/1]ip address 172.16.0.14 30 [r7-GigabitEthernet0/0/1]int l0 [r7-LoopBack0]ip address 172.16.6.1 24 [r7-LoopBack0]ospf network-type broadcast [r7-LoopBack0]int l 1 [r7-LoopBack1]ip address 132.1.1.7 32 [r7-GigabitEthernet0/0/2]ip ad 78.1.1.1 24 R6配置 [r6]int g0/0/2 [r6-GigabitEthernet0/0/2]ip address 172.16.0.13 30 [r6-GigabitEthernet0/0/2]int g0/0/1 [r6-GigabitEthernet0/0/1]ip address 172.16.0.18 30 [r6-GigabitEthernet0/0/1]int l 0 [r6-LoopBack0]ip address 172.16.5.1 24 [r6-LoopBack0]int l1 [r6-LoopBack1]ip address 132.1.1.6 32 [r6-LoopBack1]int l 0 [r6-LoopBack0]ospf network-type broadcast R5配置 [r5]int g0/0/01 [r5-GigabitEthernet0/0/1]ip address 172.16.0.17 30 [r5-GigabitEthernet0/0/1]int g0/0/0 [r5-GigabitEthernet0/0/0]ip address 172.16.0.22 30 [r5-GigabitEthernet0/0/0]int l0 [r5-LoopBack0]ip address 172.16.4.1 24 [r5-LoopBack0]int l1 [r5-LoopBack1]ip address 132.1.1.5 32 [r5-LoopBack0]ospf network-type broadcast R8配置 [r8]int g0/0/0 [r8-GigabitEthernet0/0/0]ip address 78.1.1.2 24 [r8-GigabitEthernet0/0/0]int l0 [r8-LoopBack0]ip address 8.8.8.8 24 [r8-LoopBack0]int l1 [r8-LoopBack1]ip address 132.1.1.8 32 现在配置AS2中ospf仅以R3作为例子 [r3]ospf 1 [r3-ospf-1]area 0 [r3-ospf-1-area-0.0.0.0]network 172.16.0.0 0.0.255.255 然后开配置BGP
先在R1和R2环回1之间配置两条路由保证可达R7和R8同理下面仅以R1和R2做例子 [r1]ip route-static 132.1.1.2 32 12.1.1.2 [r2]ip route-static 132.1.1.1 32 12.1.1.1 测试可以ping通
配置BGP 、BGP间建邻仅以R1、R2、R3作为例子 [r1]bgp 1 [r1-bgp]router-id 1.1.1.1 [r1-bgp]peer 12.1.1.2 as-number 2 [r2]bgp 64512 [r2-bgp]router-id 2.2.2.2 [r2-bgp]confederation id 2 [r2-bgp]confederation peer-as 64513 [r2-bgp]peer 12.1.1.1 as-number 1 [r2-bgp]peer 132.1.1.3 as-number 64512 [r2-bgp]peer 132.1.1.3 connect-interface LoopBack 1 [r2-bgp]peer 132.1.1.5 as-number 64513 [r2-bgp]peer 132.1.1.5 connect-interface LoopBack 1 [r2-bgp]peer 132.1.1.5 ebgp-max-hop 2 [r3]bgp 64512 [r3-bgp]router-id 3.3.3.3 [r3-bgp]confederation id 2 [r3-bgp]peer 132.1.1.2as-number 64512 [r3-bgp]peer 132.1.1.2 connect-interface LoopBack 1 [r3-bgp]peer 132.1.1.4 as-number 64512 [r3-bgp]peer 132.1.1.4 connect-interface LoopBack 1 然后打破水平分割仅以R3作为例子 [r3-bgp]peer 132.1.1.4 reflect-client R2和R7宣告时可聚合其他路由上该如何宣告就如何宣告 [r2]ip route-static 172.16.0.0 21 NULL 0 [r2-bgp]network 172.16.0.0 21 [r7]ip route-static 172.16.0.0 21 NULL 0 [r7-bgp]network 172.16.0.0 21 测试是否配置完成
