L
label
A fixed length header that an LSR uses to
forward packets along a Label Switched Path
(LSP). A label represents a FEC.
label binding
An association between a label and a FEC,
which can be advertised to neighbors to
establish an LSP.
label advertise mode
This mode (downstream unsolicited or
downstream on demand) determines when the
interface distributes label mappings to the next
hop upstream.
label distribution mode
This mode (independent or ordered) specifies
how an LSR binds a label to a FEC.
Label Distribution Protocol (LDP)
Provides a mechanism for dynamic hop-by-hop
label distribution between routers in a
Multiprotocol Label Switching (MPLS) network.
LDP assigns labels to IGP-learned routes and
distributes the label bindings to its peers, to
establish label switched paths (LSP) through the
network.
LDP target address
IP address of the remote peer to which a
targeted LDP session is formed. On the Ethernet
Routing Switch 8600, this address is equivalent
to the MPLS router ID of the remote peer and the
CLIP address of the egress LER.
