Hi

By using HSRP as well as IP SLA to monitor the WAN IP from a client end:

Please go through with below links for the HSRP.

http://www.cisco.com/en/US/docs/switches/lan/catalyst3550/software/release/12.1_12c_ea1/configuration/guide/swhsrp.html

IP SLA Configuration :-

ip sla monitor 1

type echo protocol ipIcmpEcho (Next HOP Wan ip Address) source-interface GigabitEthernet0/1

request-data-size 10

timeout 2000

threshold 4000

frequency 5

ip sla monitor schedule 1 life forever start-time now

track 104 rtr 1 reachability

delay down 8 up 30

When the link is down, traffic is switched to another link.
