If mesh kind ofbehavior is required, split horizon group needs to be configured.If split horizon group is configured, auto SDP will not forward the traffic between them.The no form of the command removes the group name from the configuration.Parameters group-name — Specifies the name of the split horizon group to which the SDP belongs.Values A split horizon group is by default not created in a pw-template.Item DescriptionSyntax vc-type {ether | vlan}Context config>service>pw-templateDescription This command overrides the default VC type signaled for the binding to the far end SDP. TheVC type is a 15 bit-quantity containing a value which represents the type of VC. The actualsignaling of the VC type depends on the signaling parameter defined for the SDP. If signalingis disabled, the vctype command can still be used to define the dot1q value expected by thefar-end provider equipment.A change of the bindings VC type causes the binding to signal the new VC type to the far endwhen 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 0x0004.Parameters ether — Defines the VC type as Ethernet. The ethernet and vlan keywords are mutuallyexclusive. When the VC type is not defined, the default is Ethernet for spoke SDP bindings.Defining Ethernet is the same as executing no vc-type and restores the default VC type forthe spoke SDP binding (hex 5).vlan — Defines the VC type as VLAN. The ethernet and vlan keywords are mutuallyexclusive. When the VC type is not defined, the default is Ethernet for spoke SDP bindings.
