VPLS Service Configuration Commands

the SDP. If signaling is disabled, the vc-type command can still be used to define the dot1q value
expected by the far-end provider equipment. A change of the bindings VC type causes the
binding to 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.
Values ether, vlan
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.
The VLAN VC-type requires at least one dot1Q tag within each encapsulated Ethernet packet
transmitted to the far end.
split-horizon-group group-name — Specifies the name of the split horizon group to which the SDP
belongs.
