联邦综合实验

 

1.整个AS2的IP地址为172.16.0.0/16，请合理划分（AS间的骨干链路IP地址随意定制）

2.AS1存在两个环回，一个地址为192.168.1.0/24该地址不能在任何协议中宣告；AS3中存在两个环回，一个地址为192.168.2.0/24该地址不能在任何协议中宣告，最终要求这两个环回可以互相通讯 As1的另一个环回为10.0.0.0/24，AS3的另一个环回为11.0.0.0/24

1.首先使用ospf建立通讯连接

[r2]ospf 1 router-id 2.2.2.2
[r2-ospf-1]a 0
[r2-ospf-1-area-0.0.0.0]network 172.16.0.0 0.0.255.255
 
 
[r3]ospf 1 router-id 3.3.3.3
[r3-ospf-1]a 0
[r3-ospf-1-area-0.0.0.0]network 172.16.0.0 0.0.255.255
 
 
[r4]ospf 1 router-id 4.4.4.4
[r4-ospf-1]a 0
[r4-ospf-1-area-0.0.0.0]network 172.16.0.0 0.0.255.255
 
 
[r5]ospf 1 router-id 5.5.5.5
[r5-ospf-1]a 0
[r5-ospf-1-area-0.0.0.0]network 172.16.0.0 0.0.255.255
 
 
 
[r6]ospf 1 router-id 6.6.6.6
[r6-ospf-1]a 0
[r6-ospf-1-area-0.0.0.0]network 172.16.0.0 0.0.255.255
 
 
 
[r7]ospf 1 router-id 7.7.7.7
[r7-ospf-1]a 0
[r7-ospf-1-area-0.0.0.0]network 172.16.0.0 0.0.255.255

2.建立联邦的IBGP对等体关系

[r2]bgp 64512
[r2-bgp]confederation id 2
[r2-bgp]peer 12.0.0.1 as-number 1
[r2-bgp]peer 172.16.1.1 as-number 64512
[r2-bgp]peer 172.16.1.1 connect-interface LoopBack 0
 
 
 
[r3]bgp 64512
[r3-bgp]confederation id 2
[r3-bgp]peer 172.16.6.1 as-number 64512
[r3-bgp]peer 172.16.6.1 connect-interface LoopBack 0
[r3-bgp]peer 172.16.2.1 as-number 64512
[r3-bgp]peer 172.16.2.1 connect-interface LoopBack 0
 
//------//[r3-bgp]peer 172.16.6.1 reflect-client将r3设成RR
          [r3-bgp]peer 172.16.2.1 reflect-client
 
 
 
[r4]bgp 64512
[r4-bgp]confederation id 2
[r4-bgp]peer 172.16.1.1 as-number 64512
[r4-bgp]peer 172.16.1.1 connect-interface LoopBack 0
 
 
 
[r5]bgp 64513
[r5-bgp]confederation id 2
[r5-bgp]peer 172.16.4.1 as-number 64513
[r5-bgp]peer 172.16.4.1 connect-interface LoopBack 0	
[r5-bgp]peer 172.16.4.1 next-hop-local
 
 
 
[r6]bgp 64513
[r6-bgp]confederation id 2
[r6-bgp]peer 172.16.3.1 as-number 64513	
[r6-bgp]peer 172.16.3.1 connect-interface LoopBack 0	
[r6-bgp]peer 172.16.5.1 as-number 64513
[r6-bgp]peer 172.16.5.1 connect-interface LoopBack 0
[r6-bgp]peer 172.16.3.1 next-hop-local
[r6-bgp]peer 172.16.5.1 next-hop-local
>>>>>>>>>>将r6作为RR
[r6-bgp]peer 172.16.3.1 reflect-client 
[r6-bgp]peer 172.16.5.1 reflect-client
 
 
 
[r7]bgp 64513
[r7-bgp]confederation id 2	
[r7-bgp]peer 172.16.4.1 as-number 64513
[r7-bgp]peer 172.16.4.1 connect-interface LoopBack 0
[r7-bgp]peer 172.16.4.1 next-hop-local

3.建立联邦的EBGP对等体关系 

[r1]bgp 1
[r1-bgp]peer 12.0.0.2 as-number 2
 
 
[r2-bgp]peer 12.0.0.1 as-number 1
[r2]bgp 64512
[r2-bgp]confederation peer-as 64513	
[r2-bgp]peer 172.16.0.18 as-number 64513
[r2-bgp]peer 172.16.0.18 ebgp-max-hop
 
 
[r4]bgp 64512
[r4-bgp]confederation peer-as 64513
[r4-bgp]peer 172.16.0.42 as-number 64513
[r4-bgp]peer 172.16.0.42 ebgp-max-hop 
 
 
[r5]bgp 64513
[r5-bgp]confederation peer-as 64512	
[r5-bgp]peer 172.16.0.17 as-number 64512
[r5-bgp]peer 172.16.0.17 ebgp-max-hop
 
 
[r7]bgp 64513
[r7-bgp]peer 78.0.0.2 as	
[r7-bgp]peer 78.0.0.2 as-number 3
 
 
[r7]bgp 64513
[r7-bgp]confederation peer-as 64512
[r7-bgp]peer 172.16.0.41 as-number 64512
[r7-bgp]peer 172.16.0.41 ebgp-max-hop
 
 
[r8]bgp 3
[r8-bgp]network 11.0.0.1 24
[r8-bgp]peer 78.0.0.1 as-number 2

4. 将下一跳的属性修改为自身

[r2-bgp]peer 172.16.1.1 next-hop-local
[r3-bgp]peer 172.16.6.1 next-hop-local
[r3-bgp]peer 172.16.2.1 next-hop-local
[r4-bgp]peer 172.16.1.1 next-hop-local

5.r2设置空接口防止环路并宣告AS 2内的环回（r7同样的配置）

[r2]ip route-static 172.16.0.0 16 NULL 0
[r2-bgp]network 172.16.0.0 16

6.给两个固定环回搭建虚拟隧道

[r1-Tunnel0/0/0]display this 
[V200R003C00]
#
interface Tunnel0/0/0
 ip address 192.168.3.1 255.255.255.0 
 tunnel-protocol gre
 source 10.0.0.1
 destination 11.0.0.1
#
return
 
--------------------------------------------------------------
[r8-Tunnel0/0/0]display this
[V200R003C00]
#
interface Tunnel0/0/0
 ip address 192.168.3.2 255.255.255.0 
 tunnel-protocol gre
 source 11.0.0.1
 destination 10.0.0.1
#
return

7.在r1和r8上写个静态控制流量方向

[r1]ip route-static 192.168.2.0 24 192.168.3.2
[r8]ip route-static 192.168.1.0 24 192.168.3.1

8.检查实验要求是否达到
