Perform a search on your question within this group. This question
comes along about once a month. Basically you need to connect both
routers to your 'core', and ensure that they are advertising their
default routes back to the core via the same IGP. On the core side,
you need to ensure that the two default routes have the same metric,
and provided you are using Ripv2, OSPF, or EIGRP, it will load
balance.

However, this only manages outbound traffic. Depending which ISP you
go out, which website or external network you are accessing, and how
your ISP is advertising your network will determine which path the
traffic takes back. Considering your internet traffic could be much
higher download than upload, load balancing externally will only help
you so much.......
