思科如何配置IP SLA路由联动
R871(config)#track 65 rtr 65 reachability
3)定义icmp失效时效
scheduler max-task-time 5000
4)定义需要指定源路由的ip地址
access-list 68 permit 192.168.68.0 0.0.0.255
5)配置路由策略
route-map test permit 10
match ip address 68
set ip next-hop verify-availability 192.168.65.2 10 track 65
set ip next-hop verify-availability 192.168.64.2 64 track 64
exit
6)接口应用路由策略
interface FastEthernet4
ip address 192.168.66.2 255.255.255.0
ip policy route-map test
exit
7)缺省路由应用track
ip route 0.0.0.0 0.0.0.0 192.168.64.2 10 track 64
ip route 0.0.0.0 0.0.0.0 192.168.65.2 100 track 65

配置SAA检查连通性。并跟踪这结果。很精巧的实现思路。
ip sla 65

ip sla schedule 65 life forever start-time now

track 64 rtr 64 reachability
track 65 rtr 65 reachability
定义访问控制列表，permit选项为需要重定向的数据包
access-list 168 deny ip 192.168.68.0 0.0.0.255 192.168.64.0 0.0.0.255
access-list 168 deny ip 192.168.68.0 0.0.0.255 192.168.65.0 0.0.0.255
access-list 168 permit ip 192.168.68.0 0.0.0.255 any
定义策略路由
route-map test permit 10
match ip address 168
set ip next-hop verify-availability 192.168.65.2 10 track 65
set ip next-hop verify-availability 192.168.64.2 64 track 64
