mscRtgRsGatewaySelectionAlg 1.3.6.1.4.1.562.36.2.1.40.2.12.1.18

This attribute indicates the type of algorithm to use when a route to the destination has to be selected indirectly through a gateway node. The following types of algorithms are available: cost based, random, and legacy. For cost based algorithm, RouteSelector selects gateway node that advertised it can reach the destination at the smallest cost. For random algorithm, RouteSelector selects randomly any gateway node that advertised it can reach the destination. For legacy algorithm, RouteSelector selects a complete route to the destination without attempting to route through gateway nodes. This is only possible during single to multi topology region migration, or cluster migration but before such migration is complete. During such migrations routing to the destination is initially attempted through gateway nodes, but if such routing fails then legacy routing is attempted.
