I have a requirement to load balance 2 internet links to the same provider. what is the better option? multipath or multi-hop BGP (using loopback to peer). beside using single peer and multipeer what would be the advantage and dis-advantage of using these load sharing methods.
In addition to this, per-destination would not help in terms of downllink traffic over multiple links between your router and ISP router.Infact, your customer may start complainig of download problems like FTP etc and would result in congestion on single link.
Thanks for all your comment. After reading your comments I think it makes more sense to use ebgp-multihop. It would have been nice to terminate to two different ISP routers, but because of RR etc in the ISP network we have to terminate to the same router. The advantage highlighted by Phillip on single neighbout statement on the ISP makes sense to both the customer and the ISP.
Gaurav, I will take note of your concern on single link saturation. This is a high speed connectivity so I do not see this problem. In the past I have used 'per-packet' load sharing, so if there are any problems I will not rule out using this method.
BTW, static is not an option here as the customer has multiple upstream providers and is using community tag from these service providers.
