Cisco IOS 15.x和SLA跟踪的冗余互联网接入

Question

各位，

我正试图让SLA跟踪在一个有两个宽带互联网连接的路由器上工作，NAT和SLA跟踪。

这是我在IOS 12.x上做了很多次的事情，而且相对简单。

我面临的问题是，这个特定的客户路由器(思科1921)运行的是IOS 15.1，以前的语法(ip xx)不再有效。相反，它被思科设置服务器和响应者的新方法所取代。

因此，这就是我在IOS 12.x上工作的配置中的一个片段，它通过连接到各自ISP宽带路由器的两个FE接口进行跟踪：

----
track 1 rtr 1 reachability
  delay down 15 up 10

track 2 rtr 2 reachability
  delay down 15 up 10

ip sla 1
  icmp-echo 10.10.10.1 source-interface Fastethernet0/0
  timeout 1000
  threshold 40
  frequency 3

ip sla 2
  icmp-echo 10.10.20.1 source-interface Fastethernet0/1
  timeout 1000
  threshold 40
  frequency 3

route-map nat-1 permit 10
  match ip address 100
  match interface FastEthernet0/0

route-map nat-2 permit 10
  match ip address 100
  match interface FastEthernet0/1

ip sla schedule 1 life forever start-time now
ip sla schedule 2 life forever start-time now

access-list 100 permit ip 192.168.108.0 0.0.0.255 any

ip nat inside source route-map nat-1 interface FastEthernet0/0 overload
ip nat inside source route-map nat-2 interface FastEthernet0/1 overload

ip route 0.0.0.0 0.0.0.0 FastEthernet0/0 track 1
ip route 0.0.0.0 0.0.0.0 FastEthernet0/1 track 2
----

上面的语法都超出了IOS15.x和SLA引擎3.0的窗口。

有什么想法吗？

谢谢。

随着新的版本15软件培训，需要一个数据许可证的IP SLA在思科1921路由器。请包括路由器的显示版本，让我们看看，你已经安装了什么许可证。基本许可证只包括IP SLA响应程序。

在许可证升级之后，您可以使用上面指定的命令/配置。
