求助ROS IPsec连接的问题，高手请进
现在ROS与CISCO的2811进行VPN连接，是site-site的方式，我在网上查了一些资料，按以下文章做了连接：RouterOS的大致配置过程：
================================
RouterOS是在Vmware中进行测试了，虚拟了两个接口Ether1和Ethernet2， Ether1 的ip地址为192.168.1.18/24, Ether2的ip地址为10.1.1.1/24。
IPSec部分的配置命令为：
1）设置IKE Phase1的具体参数：
/ip ipsec peer add address=192.168.1.28 secret="cisco123" enc-algorithm=des
2）设置IKE Phase2的具体参数：
主要设置包括加密传输的算法和认证方式，缺省的auth-algorithm是sha1
/ip ipsec proposal set default enc-alogrithms=des
3）详细设置需要加密的数据流及IPSecVPN的方式:Tunnel/Transport Mode等
/ip ipsec policy add src-address=10.1.1.0/24 dst-address=10.1.2.0/24 action=encrypt tunnel=yes sa-src=192.168.1.18 sa-dst=192.168.1.28
另外，如果为了采用更强的加密方式3DES, 修改两者的IKE Phase1和Phase2的参数就可以了，但一定要匹配，才能保证IKE SA和IPSec SA的成功建立。

但是我设好后总是不能通，只有
> ip ipsec installed-sa print
Flags: A - AH, E - ESP, P - pfs, M - manual 其他的信息没有
ipsec peer 和ipsec proposal 下面的状态栏显示disabled
ip policy下面的状态栏显示no phase2
考虑是伪地址优先级的原因，也更改过，就是没有办法通，请高手帮帮忙解决一下了！
