ip route 0.0.0.0 0.0.0.0 x.x.x.x

ip route 0.0.0.0 0.0.0.0 x.x.x.x 10

route-map Duel-Link-route permit 1

match ip address 20

set ip default next-hop ISP 1 Peer IP

route-map Duel-Link-route permit 1

match ip address 30

set ip default next-hop ISP 2 Peer IP

this is PBR configuration with i did in My router , BUT can you explain how i can implement IPSLA with this senario

Hi,

For such thing you need to track object with IP SLA both ISPs. And match to PBRs.

Refer to this example https://supportforums.cisco.com/docs/DOC-8313

Hope it will help.
