Description

Display the entries in the Label Distribution Protocol (LDP) internal topology table. The internal topology table contains routes from inet.0 and inet.3 and is used when binding a label to a forwarding equivalence class (FEC).

Options

none

Display standard information about all entries in the LDP internal topology table for all routing instances.

brief | detail | extensive

(Optional) Display the specified level of output.

destination

(Optional) Restrict the output to entries that are longer than the specified destination prefix and prefix length.

fec-and-route

Display the show routes and the FECs.

fec-only

Display only LDP FECs.

instance instance-name

(Optional) Display entries for the specified routing instance only.

logical-system (all | logical-system-name)

(Optional) Perform this operation on all logical systems or on a particular logical system. This option is only supported on Junos OS.
