BGP Load Balancing

All,

I would like to understand how to do load balancing using BGP for my below scenario :

1) 2 ISP Link - L2 (MPLS) (500 Mbps + 500 Mbps)

2) Terminated on a single core switch (VSS)

3) BGP connectivity with another switch VSS

I would need to do a BGP load balance to use both link as active active and load needs to be equally devided/balanced.

Please suggest how i can achieve it. If possible share the configuration as well.

Hello,

do you run eBGP with your providers ?

You could use AS Prepending:

or 

BGP Load Balancing with Community Strings:
