Parameters
independent: Specifies Independent label distribution mode. In this mode, an LSR can distribute label mappings to the upstream LSR at any time.
ordered: Specifies Ordered label distribution mode. In this mode, an LSR distributes a label mapping for an FEC to the upstream LSR only when one of the following events occurs:
The LSR receives a label mapping for that FEC from the downstream LSR.
The LSR is the egress node of that FEC.
Usage guidelines
In Ordered mode, an LSR can determine that the downstream LSR has established an LSP when the LSR receives an FEC-label mapping from the downstream LSR.
The Independent mode enables faster LSP convergence because each LSR independently advertises labels without waiting for labels from downstream LSRs.
