ether — Defines the VC type as Ethernet. The ethernet, vlan, and vpls keywords are mutually
exclusive. When the VC type is not defined then the default is Ethernet for spoke SDP bindings.
Defining Ethernet is the same as executing no vc-type and restores the default VC type for the
spoke SDP binding. (hex 5)
vlan — Defines the VC type as VLAN. The ethernet, vlan, and vpls keywords are mutually
exclusive. When the VC type is not defined then the default is Ethernet for spoke SDP bindings.
vpls — Defines the VC type as VPLS. The ethernet, vlan, and vpls keywords are mutually
exclusive. When the VC type is not defined then the default is Ethernet for spoke SDP bindings.
Defining Ethernet is the same as executing no vc-type and restores the default VC type for the
spoke SDP binding.

Syntax spoke-sdp sdp-id[:vc-id] [vc-type {ether | vlan}] [split-horizon-group group-name]
no spoke-sdp sdp-id[:vc-id]
Context config>service>vpls
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 VPLS 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.
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 No sdp-id is bound to a service.
Special Cases VPLS — Several SDPs can be bound to a VPLS service. Each SDP must use unique vc-ids. An error
message is generated if two SDP bindings with identical vc-ids terminate on the same router.
Split horizon groups can only be created in the scope of a VPLS service.
Parameters sdp-id — The SDP identifier.
Values 1 — 17407
vc-id — The virtual circuit identifier.
Values 1 — 4294967295
vc-type — This command overrides the default VC type signaled for the spoke or mesh binding to
the far end of the SDP. The VC type is a 15 bit-quantity containing a value which represents the
type of VC. The actual signaling of the VC type depends on the signaling parameter defined for
