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
a FEC to the upstream LSR only when the LSR receives a label mapping for that FEC from the downstream
LSR or 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 a 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.
Examples
# Set the Independent LDP label distribution mode for the public network.
