BGP routes can inherit flexible tunnel encapsulation information from associated static routes
BGP can inherit the encapsulation information for the flexible route from the associated static route. The device can then use the static route's indirect next hop to encapsulate traffic in the flexible tunnel without intermediate steps. This streamlines your network configuration. To enable this feature, configure the preserve-nexthop-hierarchy option at the [edit routing-instances routing-instance-name routing-options resolution rib routing-instance .inet.0] hierarchy level. To view the details of the ultimate next hop, use the show route extensive route expanded-nh command.
