OER/PfR with BGP for inbound load sharing

Wed Jul 14 14:55:52 UTC 2010

Does anyone have any experience with using OER for inbound load sharing? I am looking to see if people are generaly satisfied with it's abilities or if I should look for other options to balance my inbound traffic. I have two connections (one 50Mb and one 25Mb) with partial BGP routes across two routers that I would like to move from an active/standby model to a more active/active model. Our organization moves very little information out of our forward facing precessence servers so outbound balancing is not as important. Almost 80% of our inbound traffic is VPN as well so using application discovery isn't that important either.

Some specific questions I have are:
Is OER aware of traffic-shape or bandwidth contstraints that are applied to an interface?
Does OER simply add prepending for my advertised routes to my upstreams or does it actually prepend AS from inbound providers to move specific traffic from an AS to one of my underutilized connections?
Does OER have to ability to control inbound traffic on a subnet level within the same AS? We receive a ton of data from a few AS numbers, so simply moving a single AS to a different connection may not be extremely effective.

Thanks.
