AR系列路由器标准ipsec的典型配置

 

【需求】

两台路由器通过internet采用ipsec tunnel方式互通。

【组网图】

 

【配置脚本】

RouterA配置脚本

#

sysname RouterA

#

radius scheme system

#

domain system

#

ike proposal 1

#

ike peer a

pre-shared-key huawei-3com

remote-address 202.0.0.2

#

ipsec proposal a

#

ipsec policy a 1 isakmp

security acl 3000

ike-peer a

proposal a

#

acl number 3000

rule 0 permit ip source 192.168.1.0 0.0.0.255 destination 192.168.2.0 0.0.0.255

#

interface Ethernet1/0/0

ip address 192.168.1.1 255.255.255.0

#

interface Serial2/0/0

link-protocol ppp

ip address 202.0.0.1 255.255.255.0

ipsec policy a

#

interface NULL0

#

ip route-static 0.0.0.0 0.0.0.0 202.0.0.2 preference 60

#

user-interface con 0

user-interface vty 0 4

#

return

RouterB配置脚本

#

sysname RouterB

#

radius scheme system

#

domain system

#

ike proposal 1

#

ike peer b

pre-shared-key huawei-3com

remote-address 202.0.0.1

#

ipsec proposal b

#

ipsec policy b 1 isakmp

security acl 3000

ike-peer b

proposal b

#

acl number 3000

rule 0 permit ip source 192.168.2.0 0.0.0.255 destination 192.168.1.0 0.0.0.255

#

interface Ethernet1/0/0

ip address 192.168.2.1 255.255.255.0

#

interface Serial2/0/0

link-protocol ppp

ip address 202.0.0.2 255.255.255.0

ipsec policy b

#

interface NULL0

#

ip route-static 0.0.0.0 0.0.0.0 202.0.0.1 preference 60

#

user-interface con 0

user-interface vty 0 4

#

return

【验证】

确认RouterA上建立ike sa

[RouterA]disp ike sa

total phase-1 SAs:  1

connection-id  peer            flag        phase   doi

----------------------------------------------------------

2          202.0.0.2       RD|ST         1     IPSEC

3          202.0.0.2       RD|ST         2     IPSEC

 

flag meaning

RD--READY ST--STAYALIVE RL--REPLACED FD--FADING TO--TIMEOUT

 

【提示】

1、 当路由器即需要配置ipsec,又需要使用NAT的,一定要在NAT

    的ACL中deny掉ipsec保护的流。否则需要进行ipsec保护的流

    会先会被NAT的ACL匹配,进行NAT,而无法触发ipsec的建立。
