Starting in Junos OS 13.3R3, for MX Series 3D Universal Edge routers with modular port
concentrators (MPCs) only, you can configure consistent load balancing, which prevents
the reordering of all flows to active paths in an equal-cost multipath (ECMP) group when
one or more next-hop paths fail. Only flows for paths that are inactive are redirected to
another active next-hop path. Flows mapped to servers that remain active are maintained.
This feature applies only to external BGP peers.
