A traffic manager obtains (a) a representation of an association between a set of networking destinations and a routing option group, and (b) a policy for selecting routing options from the group for network packets. For a network packet directed to one of the destinations, the traffic manager selects one of the routing options of the group based on the policy, and causes the packet to be transmitted to the destination along a path. The path includes, as a next-hop address, a network address associated with the selected routing option.
