ether — Defines the VC type as Ethernet. The ethernet and vlan keywords are mutually exclusive.
vlan — Defines the VC type as VLAN. The ethernet and vlan keywords are mutually exclusive.
no endpoint — Removes the association of a spoke SDP with an explicit endpoint name.
endpoint endpoint-name — Specifies the name of the service endpoint.

This command enables the use of the hash label on a VLL or VPLS service bound to LDP or RSVP
Description
SDP. This feature is not supported on a service bound to a GRE SDP. This feature is also not
supported on multicast packets forwarded using RSVP P2MP LPS or mLDP LSP in both the base
router instance and in the multicast VPN (mVPN) instance. It is, however, supported when
forwarding multicast packets using an IES spoke-interface.
When this feature is enabled, the ingress data path is modified such that the result of the hash on the
packet header is communicated to the egress data path for use as the value of the label field of the
hash label. The egress data path appends the hash label at the bottom of the stack (BoS) and sets the
S-bit to one (1).
In order to allow applications where the egress LER infers the presence of the hash label implicitly
from the value of the label, the Most Significant Bit (MSB) of the result of the hash is set before
copying into the Hash Label. This means that the value of the hash label will always be in the range
[524,288 - 1,048,575] and will not overlap with the signaled/static LSP and signaled/static service
label ranges. This also guarantees that the hash label will not match a value in the reserved label
range.

signal the new VC type to the far end when signaling is enabled.
VC types are derived according to IETF draft-martini-l2circuit-trans-mpls.
The VC type value for Ethernet is 0x0005.
The VC type value for an Ethernet VLAN is 0x0004.
The VC type value for a VPLS service is defined as 0x000B.
ethernet
Values
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.
When the VC type is not defined then the default is Ethernet for spoke SDP bindings.
The VLAN VC-type requires at least one dot1Q tag within each encapsulated Ethernet packet
transmitted to the far end.
