no spoke-sdp sdp-id [:vc-id] vc-type {ether|ipipe} [create]
Context config>service>vprn>interface
Description This command binds a service to an existing Service Distribution Point (SDP).
A spoke SDP is treated like the equivalent of a traditional bridge “port” where flooded traffic received
on the spoke SDP is replicated on all other “ports” (other spoke and mesh SDPs or SAPs) and not
transmitted on the port it was received.
The SDP has an operational state which determines the operational state of the SDP within the
service. For example, if the SDP is administratively or operationally down, the SDP for the service
will be down.
The SDP must already be defined in the config>service>sdp context in order to associate an SDP
with a service. If the sdp sdp-id is not already configured, an error message is generated. If the sdp-id
does exist, a binding between that sdp-id and the service is created.
SDPs must be explicitly associated and bound to a service. If an SDP is not bound to a service, no far-
end 7750 SR devices can participate in the service.
Class-based forwarding is not supported on a spoke SDP used for termination on an IES or VPRN
services. All packets are forwarded over the default LSP.
The no form of this command removes the SDP binding from the service. The SDP configuration is
not affected; only the binding of the SDP to a service. Once removed, no packets are forwarded to the
far-end router.
Default none
Special Cases VPRN — Several SDPs can be bound to a VPRN service. Each SDP must be destined to a different
7750 SR router. If two sdp-id bindings terminate on the same 7750 SR, an error occurs and the
second SDP is binding is rejected.
sdp-id — The SDP identifier.
Values 1 — 17407
vc-id — The virtual circuit identifier.
Values 1 — 4294967295
vc-type — The encapsulation and PW type for the spoke-sdp.
Values ether—Ethernet PW. This is the default.
ipipe—IP PW..
