Here are the fields on this screen:
General Settings
- Keepalive interval —(1 - 65535 seconds).
-
Keepalive timeout —(1 - 65535 seconds)
-
Preference —Set the route preference level for LDP routes. (0 - 255)
Graceful Restart
Configure graceful restart attributes. Enable LDP graceful restart on the LDP master protocol
instance.
-
Recovery time —Time required for recovery (120 - 1800 seconds) Specifies the amount of time a
router waits for LDP to restart gracefully. Configure the recovery time, in seconds. Range: 120
through 1800 seconds. Default: 140 seconds
-
Maximum recovery time —Maximum time stale mappings are maintained (seconds). Specify
the maximum period (in seconds) to wait before giving up an attempt to gracefully restart.
Range: 140 through 1900 seconds. Default: 140 seconds
-
Disable —Disable graceful restart. Explicitly disable LDP on an interface, or explicitly disable
LDP graceful restart.
-
Helper Disable —Disable the graceful restart helper capability. Disables helper mode for LDP
graceful restart. When helper mode is disabled, a router cannot help a neighboring router that
is attempting to restart LDP. Helper mode is enabled by default on all routing protocols
(including LDP) that support graceful restart.
Options
- Deaggregate —Deaggregate FECs into separate labels. Control forwarding equivalence class
(FEC) deaggregation on the router. Deaggregation is disabled on the router by default.
-
No deaggregate —Don't deaggregate FECs into separate labels, aggregate FECs.
-
Explicit null —Advertise the EXPLICIT_NULL label for egress FECs. Advertise label 0 to the
egress router of a label-switched path (LSP). If you do not include the explicit-null statement
in the Multiprotocol Label Switching (MPLS) configuration, label 3 (implicit null) is
advertised.
-
No forwarding —Do not use LDP ingress routes for forwarding. Do not add ingress routes to the
inet.0 routing table even if traffic-engineering bgp-igp (configured at the [edit protocols
mpls] hierarchy level) is enabled.
-
Strict targeted hellos —Do not send targeted hellos to unconfigured neighbors
-
Track igp metric —Track the IGP metric. Use the IGP route metric for the LDP routes instead of
the default LDP route metric (the default LDP route metric is 1).
