我想知道是否有一种方法可以让下面的代码在每次列出{{routemapnumber}}值时将其递增5。因此，第一个{{routemapnumber}}值将是5，然后另一个将是10，依此类推。我认为for循环可以工作，但我遇到了语法问题。

route-map RDS_FILTER permit {{routemapnumber}}
 match ip address {{item.aclnumber}}
 set ip next-hop verify-availability 10.4.21.157 1 track {{item.slanumber}}
 set ip next-hop 192.168.2.58
route-map RDS_FILTER permit {{routemapnumber}}
 match ip address 109
 set ip next-hop verify-availability 10.4.21.157 1 track 1
 set ip next-hop 192.168.2.58
route-map RDS_FILTER permit {{routemapnumber}}
 match ip address 108
route-map RDS_FILTER permit {{routemapnumber}}
match ip address 107
 set ip next-hop 192.168.0.2
route-map RDS_FILTER permit {{routemapnumber}

如果没有很多行，我会硬编码增量，例如：

route-map RDS_FILTER permit {{routemapnumber}}
 match ip address
 set ip next-hop verify-availability 10.4.21.157 1 track
 set ip next-hop 192.168.2.58
route-map RDS_FILTER permit {{routemapnumber + 10}}
 match ip address 109
 set ip next-hop verify-availability 10.4.21.157 1 track 1
 set ip next-hop 192.168.2.58
route-map RDS_FILTER permit {{routemapnumber + 15}}
 match ip address 108
route-map RDS_FILTER permit {{routemapnumber + 20}}
match ip address 107
 set ip next-hop 192.168.0.2
route-map RDS_FILTER permit {{routemapnumber + 25}}

如果这对您来说不是一个好的选择，您可以在打印之前使用set语句递增变量，从而向模板中添加一些数学逻辑：

{% set routemapnumber = routemapnumber + 5 %}

完整示例：

route-map RDS_FILTER permit {{routemapnumber}}
 match ip address
 set ip next-hop verify-availability 10.4.21.157 1 track
 set ip next-hop 192.168.2.58
route-map RDS_FILTER permit {% set routemapnumber = routemapnumber + 5 %}{{routemapnumber}}
 match ip address 109
 set ip next-hop verify-availability 10.4.21.157 1 track 1
 set ip next-hop 192.168.2.58
route-map RDS_FILTER permit {% set routemapnumber = routemapnumber + 5 %}{{routemapnumber}}
 match ip address 108
route-map RDS_FILTER permit {% set routemapnumber = routemapnumber + 5 %}{{routemapnumber}}
match ip address 107
 set ip next-hop 192.168.0.2
route-map RDS_FILTER permit {% set routemapnumber = routemapnumber + 5 %}{{routemapnumber}}
