Policy Based Routing for multiple tracking options question.

Hi Guys

I have the following scenario


corporate router(B)-----(A)central router(B)-----(A)ADSL 
Router(B)----INTERNET
                                                            
        PC's
I have a range of PC's whose default gateway is the IP
address of central 
router's B interface and internet traffic from the PC's
are  routed to the 
internet via ADSL router in normal operation (ADSL router is
not a Cisco, 
central router is a Cisco 1811). I would like a option that
if the ADSL link 
is down that internet traffic would be automatically
re-routed via the 
corporate router(cisco 2600).(Routing between central router
& adsl router & 
ISP is static only)
When ADSL is down normally you are not able to see the WAN
ip address (ip 
address of interface B on ADSL router). Reading PBR with
multiple tracking I 
was wonderingif I configured central router with PBR to set
a ping to ADSL 
router(B) ip address that in the event of the link failing
central router 
would re-route to corporate router.

Your thoughts please

Thanks
Simon

PS ip address of central router B and ADSL router A is on
same subnet, as is 
central Router A and corporate router B interfaces.
