Command Explanation vpls VPLS-NAME Use the vpls command in global configuration mode to create a VPLS and enter VPLS configuration mode. Use no vpls command in global configuration mode to delete a VPLS. The name range 1 - 32 characters. vpls-id VPLS-ID Use the vpls-id command in VPLS configuration mode to set VPLSID of a VPLS. xconnect vpls VPLS-NAME Use xconnect vpls command in interface configuration mode to create a local AC in a VPLS. Use no xconnect vpls command in interface configuration mode to delete a local AC in a VPLS. peer IP-ADDRESS [{network | spoke}] Use the peer command in VPLS configuration mode to create a peer i.e. a psuedowire in a VPLS. Use no peer command in VPLS configuration mode to delete a peer in a VPLS. encapsulation {raw | tagged} Use encapsulation command in VPLS configuration mode to set pseudowire encapsulation type of a VPLS Table 35-1 VPLS (Abbreviated) command list DGS-6600 Configuration Guide 375

MPLS Tunnel
MPLS tunnels are set up between PEs to aggregate MPLS packet traffic. The multiple PWs
belonging to different VPLS instances can be carried in a single MPLS tunnel from one PE to
another PE.
VPLS Service
In the PE, a Virtual Switching Instance (VSI) for a VPLS will map multiple ACs to multiple PWs. It
makes the forwarding decision when a frame is forwarded from an AC to a PW or a frame is
forwarded from a PW to an AC in the PE. A VPLS instance consists of a set of VSI form emulated
LAN over a provider network.
1.Emulated Service
The service emulated by a VPLS instance can be Ethernet service or Ethernet VLAN service. This
decides the emulated service on the PWs in this VPLS. If VPLS service is the Ethernet service, the
encapsulation mode of the PWs is Ethernet raw mode; If VPLS service is the Ethernet VLAN
service, the encapsulation mode of PWs is Ethernet tagged mode.
In the default, the emulated service of a VPLS is Ethernet VLAN service.
2.MTU
The MTU (Maximum Transmission Unit) of the VPLS must be the same across all the PWs in the
mesh.
3.L2 Protocols
802.3x Pause frames send from a CE will not be transported over a VPLS. L2 Protocol PDUs (e.g.
STP PDUs, GVRP PDUs, etc) need to be sent from a local CE to remote CEs are simply tunneled
through the provider network.
VPLS Configuration Commands
listed below are some of the more commonly used VPLS commands, used in the examples below.
Command
Explanation
vpls
VPLS-NAME
Use the vpls command in global configuration mode to create a
VPLS and enter VPLS configuration mode. Use
no
vpls
command in global configuration mode to delete a VPLS.
The name range 1 - 32 characters.
vpls-id
VPLS-ID
Use the
vpls-id
command in VPLS configuration mode to set
VPLSID of a VPLS.
xconnect vpls
VPLS-NAME
Use
xconnect vpls
command in interface configuration mode to
create a local AC in a VPLS. Use
no xconnect vpls
command in
interface configuration mode to delete a local AC in a VPLS.
peer
IP-ADDRESS
[{network | spoke}]
Use the
peer
command in VPLS configuration mode to create a
peer i.e. a psuedowire in a VPLS. Use
no
peer command in
VPLS configuration mode to delete a peer in a VPLS.
encapsulation {raw | tagged}
Use
encapsulation
command in VPLS configuration mode to set
pseudowire encapsulation type of a VPLS
