If you are taking full routes you can do manual traffic engineering
(localpref certain as-paths higher/lower between the two links).
There are also commercial products that will do this automatically
for you (Avaya CNA, Internap FCP etc).
If you have connections to differnt ISPs and cannot
take full routes then requesting partial routes
and/or filtering received routes may enable you to
do some path based TE.
If you have multiple links to the same ISP you can
set maximum-paths for bgp to install multiple next-hops
for the same path in the fib.
