Hi, What techniques are available to load-share traffic on two links (of equal bandwidth) to the same ISP (same AS) given that BGP only enters the best path into the RIB? We could announce our prefixes over both links, but splitting the preferred path announcements over the two links, either using MED or ISP communities, but this only really addresses inbound traffic. More of an issue is trying to load-share outbound traffic; we assume we'll learn the same set of prefixes over both links from the same ISP - one technique may be to simple split the IPv4 address space in half and local-pref accordingly to prefer one link or the other depending on the destination IP prefix?
