out-label — Specify the LSR to swap the label. If configured, then the LSR should swap the label
with the configured swap-label. If not configured, then the default action is pop if the next-hop
parameter is not defined.
NOTE: The next-hop, advertised-label, swap-label parameters are all optional. If next-hop is
configured but no swap label specified, then it will be a swap with label 3, such as, pop and
forward to the next-hop. If the next-hop and swap-label are configured, then it is a regular swap.
If no parameters are specified, then a pop and route is performed.
Values 16 — 1048575
in-label — Specifies the number of labels to send to the peer associated with this FEC.
Values 32 — 1023
pop — Specifies to pop the label and transmit without the label.
interface interface-name — Specifies the name of the interface the label for the originated FEC is
swapped to. For an unnumbered interface, this parameter is mandatory since there is no address
for the next-hop. For a numbered interface, it is optional.
[no] graceful-restart
config>router>ldp
This command enables graceful restart helper.
The no form of the command disables graceful restart. Note that graceful restart helper configuration
changes, enable/disable or change of a parameter, will cause the LDP session to bounce.
no graceful-restart (disabled) — Graceful-restart must be explicitly enabled.
[no] implicit-null-label
config>router>ldp
This command enables the use of the implicit null label. Use this command to signal the IMPLICIT
NULL option for all LDP FECs for which this node is the egress LER.
The no form of this command disables the signaling of the implicit null label.
