ECMP: Disable hierarchical ECMP

You can disable hierarchical equal-cost multipath (ECMP) groups for LDP forwarding equivalence classes (FECs) at system start time. Hierarchical ECMP is enabled by default. Disabling this feature effectively increases the number of ECMP groups. To disable hierarchical ECMP, include the no-hierarchical-ecmp statement at the [edit forwarding-options] hierarchical level. Disabling hierarchical ECMP causes the Packet Forwarding Engine to restart. To reenable hierarchical ECMP, issue the following command: delete forwarding-options no-hierarchical-ecmp.
