command before the no far-end command can be executed. Removing the far end IP address will
cause all lsp-name associations with the SDP to be removed.
Default
none
Parameters
ip-address — The system address of the far-end 7750 SR for the SDP in dotted decimal notation.
ldp
Syntax [no] ldp
Context config>service>sdp
Description
This command enables LDP-signaled LSP's on MPLS-encapsulated SDPs.
In MPLS SDP configurations either one LSP can be specified or LDP can be enabled. The SDP ldp
and lsp commands are mutually exclusive. If an LSP is specified on an MPLS SDP, then LDP cannot
be enabled on the SDP. To enable LDP on the SDP when an LSP is already specified, the LSP must be
removed from the configuration using the no lsp lsp-name command.
Alternatively, if LDP is already enabled on an MPLS SDP, then an LSP cannot be specified on the
SDP. To specify an LSP on the SDP, the LDP must be disabled. The LSP must have already been
created in the config>router>mpls context with a valid far-end IP address.
Default
no ldp (disabled)
lsp
Syntax lsp lsp-name
no lsp lsp-name
Context config>service>sdp
Description
This command creates associations between one or more label switched paths (LSPs) and an Multi-
Protocol Label Switching (MPLS) Service Distribution Point (SDP). This command is implemented
only on MPLS-type encapsulated SDPs.
In MPLS SDP configurations either one LSP can be specified or LDP can be enabled. The SDP ldp
and lsp commands are mutually exclusive. If an LSP is specified on an MPLS SDP, then LDP cannot
be enabled on the SDP. To enable LDP on the SDP when an LSP is already specified, the LSP must be
removed from the configuration using the no lsp lsp-name command.
Alternatively, if LDP is already enabled on an MPLS SDP, then an LSP cannot be specified on the
SDP. To specify an LSP on the SDP, the LDP must be disabled. The LSP must have already been
created in the config>router>mpls context. with a valid far-end IP address. RSVP must be enabled.
Each LSP has a preference value defined that is derived from its active path or the LSP itself. When
multiple LSPs are defined on an SDP, the LSP with the highest preference will be used for packets
transmitted to the far-end 7750 SR.
If no LSP is associated with an MPLS SDP, the SDP cannot enter the operationally up state. The SDP
can be administratively enabled (no shutdown) with no LSP associations. The lsp-name may be
