Hi,
I have 2 ISP (1=10Mbps, 2=2Mbps) terminated into 2 routers. Routers are terminated into 2 different sets of firewall & the firewall'are terminated into Core switches.
I want to achive traffic load sharing b/w these 2 ISP's in such a manner that a large part of the traffic goes via ISP1 & rest via ISP2. At any point of time if ISP1 has more latency then partial traffic will go via ISP2. If any of the link goes down, the entire load will he transferred to the other one.
Is this possible????

It might be if your able to use OER or PfR.

If your routers are running BGP, an OER config would look something like:
Border router only:
key chain key1
key 1
key-string somekey
oer border
local Loopback0
master x.x.x.x key-chain key1
Combined border/master router
key chain key1
key 1
key-string somekey
oer master
logging
!
border x.x.x.x key-chain key1
interface FastEthernet0/0 internal
interface Serial0/0 external
!
border x.x.x.x key-chain key1

interface Serial0/0 external
