We have two datacenters one in east coast and the other in west coast

We are peering with two major ISPs in each location

We want this datacenter to load balance incoming traffic geographically

How can I ensure, the east coast customers reach the East coast Data center and the west coast customers reach the West coast DC

Outbound routing policies affects inbound traffic

Inbound routing policies affects outbound traffic

Weight  & Local-Preference

AS-Path & MED

Consult with ISP before implementing routing policies !
