Loop-Detect - H3C S5820X Series Command Reference Manual

Parameters
independent: Specifies the independent label distribution control mode. In this mode, an LSR can
advertise label bindings to its connected LSRs at anytime.
ordered: Specifies the ordered label distribution control mode. In this mode, an LSR advertises to its
upstream a label binding for a FEC only when it receives a label binding for the FEC from its downstream
or when it is the egress of the FEC.
Usage guidelines
You must use the reset mpls ldp command to reset LDP sessions so that this command takes effect for those
sessions.
