Hi
I have 2 routers with 1 Mbps internet connection on each. Now I have to do the load balancing between these routers without any inetrnet load balancer.
Please suggest how can I achieve this ???

HI Shiv, [Pls RATE if HELPS]
Load balancing is not possible in a multihomed environment with two ISPs. BGP selects only the single best path to a destination among the BGP paths that are learned from different ASs, which makes load balancing impossible. . However, load sharing is possible in such multihomed BGP networks.
Refer useful link below describing multiple scenario's of BGP environments:

Hope I am Informative.
Pls RATE if HELPS

Hi Shiv,
What WAN interface is your internet connection is and what is the routing protocol. ans also let your router model.

In this case another way to investigate, to load balance traffic with two or more ISPs, is the Performance Routing (PfR, named also OER, Optimize Edge Routing):
