You are looking at wrong place. Check below ref:
http://www1.cisco.com/en/US/tech/tk365/t...html#conf1
and this note in Building Scalable Cisco Internetworks (BSCI) v3.0, page 6-46:
"BGP is not designed to perform load balancing; paths are chosen because of policy, not
based on bandwidth. BGP will choose only a single best path. Using the loopback
addresses and the neighbor ebgp-multihop command as shown in this example allows
load balancing, as well as redundancy, across the two paths between the autonomous
systems".
Pay close attention to the requirements given in question:
"multiple equal-bandwidth parallel links from a single CE router to a single ISP router over eBGP".
