GRE&IPSec试验命令

GRE&IPSec试验命令

所有的数据包都是可以看到的

 

写静态:

Ip route-static 172.16.0.0.24 10.0.0.3(tunnel 0/0/1)

静态的出接口和下一跳都要写隧道口


IPSec试验命令

清除除了物理口的IP配置的所有配置

R1:

Acl 3000

Rule 5 permit ip so 192.168.0.0 0.0.0.255des 172.16.0.0 0.0.0.255

 

R2:

Acl 3000

Rule 5 permit ip so 172.16.0.0 0.0.0.255des 192.168.0.0 0.0.0.255

 

R1:

IPsec proposal R2

创建并配置IPsec提议,默认采用esp协议、MD5认证算法和隧道封装模式

Transform esp          配置隧道采用的安全协议(默认esp)

Encapsulation-mode tunnel  配置报文的封装模式

Esp authentication-algorithm sha2-256 配置ESP协议使用的认证算法(默认MD5-HMAC-96)

Esp encryption-algorithm aes-128  配置esp的加密算法(默认DES)

Display IPsec proposal 查看IPsec提议中的配置参数

Quit                    安全提议配置完成

 

IPsec policy P1 10 manual       (manual,手动协商,)

—(创建并配置IPsec策略(P1为名字,调用使用改名字,10为***,类似acl的***)

Security acl 3000               配置IPsec策略管理的acl

Proposal R2           关联提议shanghai

Tunnel local 12.0.0.2        配置安全隧道本端地址

Tunnel remote 13.0.0.3   配置安全隧道远端地址

Sa spi outbound esp 12345

Sa spi inbound esp 54321        

——配置SA的SPI,入方向和出方向都必须设置,并且双方的必须互相对应(自动时不用配置)

Sa string-key outbound esp cipher wakout

Sa string-key inbound esp cipher wakin

  配置SA的认证秘钥,入方向和出方向都必须设置,并且双方向必须对应(自动协商时不用配置)

quit  安全策略配置完成

inte g0/0/1(连接公网的接口)

ipsec policy P1(应用)

 

验证命令:

Display IPsec policy

未使用AH,所以AH不会显示东西

查看数据包出入情况display IPsec statistics esp


GRE&IPsec

配置:

单台路由器配置

Interface tunnel 0/0/1

Ip address 10.0.0.2 8

Tunnel-protocol gre

Source 12.0.0.2

Destination 13.0.0.3

Quit

Ospf启用,建立邻居

 

Acl 3000

Rule 5 permit gre so 12.0.0.2 0.0.0.0 des13.0.0.3 0.0.0.0 (使用匹配GRE)

 

IPsec配置不变

 

Interface g0/0/0(公网接口)

IPsec policy P1
