If you want to get better control of your inbound traffic, you could talk to you ISPs. Some ISPs such as AS701 let you set the local pref and prepending through the community strings. Local Pref = 80 701:80 set localpref 80
Local Pref = 120 701:120 set localpref 120 AS Path prepend 1 701:1 prepend 1x: 701 [cust-AS] AS Path prepend 2 701:2 prepend 2x: 701 701[cust-AS] AS Path prepend 3 701:3 prepend 3x: 701 701 701[cust-AS] You always have better control of outboud traffic since you have full control of your bgp routers, but for inbound traffic tuning the above tool is pretty handy.
