This field indicates whether BGP routes with different AS_PATHs can be used as equal cost routes. If this is FALSE then DC-BGP only treats two BGP routes as equal cost if several of their attributes, including the AS_PATH, are identical. This is the default behavior. If this is TRUE then DC-BGP can treat two BGP routes as equal cost even if their AS_PATHs differ, as long as their AS_PATH lengths and other relevant attributes are the same. This allows routes with different AS_PATHs to be programmed into the forwarding table as equal cost multipath routes. When multipath-relax is enabled DC-BGP still selects one of the multipath routes as the best route to advertise to its peers. The AS_PATH advertised to peers reflects the best route but not other equal cost routes, so it does not reflect the full set of ASs on the forwarding path. This means that enabling multipath-relax can cause routing loops. Therefore multipath-relax should only be enabled if the network administrator is sure that routing loops cannot occur. This field can only be changed when the Admin Status is down.
