hcip中BGP的综合实验

目录

1.首先使用ospf建立通讯连接

 2.建立联邦的IBGP对等体关系

3.建立联邦的EBGP对等体关系

4. 将下一跳的属性修改为自身

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

6.给两个固定环回搭建虚拟隧道

7.在r1和r8上写个静态控制流量方向

8.检查实验要求是否达到


实验题目:

 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

[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

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]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

[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]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
