对于L2TP over IPsec的配置命令,具体情况可能因不同的设备和网络环境而有所不同。一般而言,我们可以按照如下步骤进行配置:
1. 配置IPsec隧道,包括设定SA、IP地址、预共享密钥等参数,将IPsec加密功能启用,具体命令可能为:
crypto isakmp policy 1
authentication pre-shared
encryption aes
hash sha
group 5
lifetime 86400
crypto isakmp key xxxxx address x.x.x.x
crypto isakmp keepalive 10 periodic
crypto ipsec transform-set esp-aes-sha esp-aes esp-sha-hmac
crypto map vpn-map 10 ipsec-isakmp
set peer x.x.x.x
set transform-set esp-aes-sha
match address 100
2. 配置L2TP协议,包括设定LAC(L2TP Access Concentrator)和LNS(L2TP Network Server)等参数,将L2TP隧道启用,具体命令可能为:
vpdn-group L2TP-Group
! Define the point of network attachment (LAC)
request-dialin
protocol l2tp
interface Virtual-PPP1
! Define the network server address (LNS)
no ip address
ppp authentication pap
ppp pap sent-username test password test
3. 配置L2TP+IPsec双重加密,将IPsec隧道和L2TP隧道结合起来实现双重加密,具体命令可能为:
vpdn-group L2TP-Group
! Activate L2TP tunnel with dial-in access
request-dialin
protocol l2tp
! LNS address
!ppp authentication chap
ppp authentication ms-chap-v2
ppp authorization vpn-auth
ppp ipcp dns 8.8.8.8
ppp ipcp route default
crypto ipsec transform-set vpn-transform esp-aes 128 esp-md5-hmac
crypto dynamic-map vpn-dynamic 1
set transform-set vpn-transform
reverse-route
exit
crypto map vpn-map 10 ipsec-isakmp dynamic vpn-dynamic
注意:以上仅是一个参考示例,实际情况中具体的配置参数和命令可能会有所不同,还需要根据实际需求进行相应调整。
