求大神指导，这样做策略路由实现分流与备份，对不对？
show route-map看不到cisco1、cisco2、cisco3、cisco4这四条策略路由匹配的数据包

route-map fenliu, permit, sequence 10
  Match clauses:
    ip address (access-lists): asd
    interface GigabitEthernet0/1
  Set clauses:
    interface GigabitEthernet0/1
  Policy routing matches: 47494525 packets, 16455413671 bytes
route-map fenliu, permit, sequence 20
  Match clauses:
    ip address (access-lists): qwe
    interface GigabitEthernet0/2
  Set clauses:

策略路由是策略路由
策略nat 是策略nat
策略路由只需要match address 然后set ip next-hop
策略nat 只需要match interfaece（出接口，即路由的出接口，从哪边出去，就走那边的nat）和match 内网的所有adress
你要想做备份，只需要做路由的备份，不需要去管nat
路由的备份只有用
match address 1
set ip next-hop verify-availability 1.1.1.1 1track 1  
set ip next-hop verify-availability 2.2.2.2 2 track2

match address 2
set ip next-hop verify-availability 2.2.2.2 1 track2
set ip next-hop verify-availability 1.1.1.1 2 track 1
写2条set ，用sla去判断
试试，我也没验证过
