Table 8 sdp command

Item Description
Syntax sdp sdp-id mpls
no sdp sdp-id
Context configure>service
Description This command creates or edits a Service Distribution Point (SDP). SDPs must be explicitly
configured.
An SDP is a logical mechanism that ties a far-end ISAM to a particular service without having
to specifically define far end SAPs. Each SDP represents a method to reach a ISAM router.
ISAM supports both signaled and non-signaled Label Switched Paths (LSPs) through the
network. Non-signaled paths are defined at each hop through the network. Signaled paths are
communicated via ldp protocol.
SDPs are created and then bound to services. Many services may be bound to a single SDP.
The operational and administrative state of the SDP controls the state of the SDP binding to
the service.
If sdp-id does not exist, a new SDP is created. When creating an SDP, the mpls keyword must
be specified. SDPs are created in the admin down state (shutdown) and the no shutdown
command must be executed once all relevant parameters are defined and before the SDP can
be used.
If sdp-id exists, the current CLI context is changed to that SDP for editing and modification. For
editing an existing SDP, the mpls keyword is not specified. If the keyword is specified for an
existing sdp-id, an error is generated and the context of the CLI will not be changed to the
specified sdp-id.
The no form of this command deletes the specified SDP. Before an SDP can be deleted, it
must be administratively down (shutdown) and not bound to any services. If the specified SDP
is bound to a service, the no sdp command will fail generating an error message specifying
the first bound service found during the deletion process. If the specified sdp-id does not exist
an error will be generated.
Default none
Parameters sdp-id — The SDP identifier.
Values: 1...17407
mpls — Specifies the SDP will use MPLS encapsulation and one or more LSP tunnels to
reach the far-end ISAM. Multiple MPLS SDPs may be created to a given destination ISAM.
Multiple MPLS SDPs to a single destination ISAM are helpful when they use divergent paths.
