Configuring FEC Originate Parameters
A FEC can be added to the LDP IP prefix database with a specific label operation on the node.
Permitted operations are pop or swap. For a swap operation, an incoming label can be swapped
with a label in the range of 16 to 1048575. If a swap- label is not configured then the default value
is 3.
A route table entry is required for a FEC with a pop operation to be advertised. For a FEC with a
swap operation, a route-table entry must exist and user configured next-hop for swap operation
must match one of the next-hops in route-table entry.
Use the following syntax to configure FEC originate parameters:
CLI Syntax: config>router>ldp
fec-originate ip-prefix/mask [advertised-label in-label]
next-hop ip-address [swap-label out-label]
fec-originate ip-prefix/mask [advertised-label in-label] pop
