Summary

Virtual Private Lan Service (VPLS) interface can be considered tunnel interface just like EoIP interface. To achieve transparent ethernet segment forwarding between customer sites.

MikroTik RouterOS implements following VPLS features:

Since version 3.17:

  • Cisco style static VPLS pseudowires (RFC 4447 FEC type 0x80), see static Cisco VPLS
  • Cisco VPLS BGP-based auto-discovery (draft-ietf-l2vpn-signaling-08), see BGP based Cisco style VPLS
  • support for multiple import/export route target extended communities for BGP based VPLS (both, RFC 4761 and draft-ietf-l2vpn-signaling-08)

General

Sub-menu: /interface vpls


List of all VPLS interfaces. This menu shows also dynamically created BGP based VPLS interfaces.

Properties

Property Description
advertised-l2mtu (integer; Default: 1500) L2MTU value advertised to remote peer.
arp (disabled | enabled | proxy-arp | reply-only; Default: enabled) Address Resolution Protocol
cisco-style (yes | no; Default: no) Specifies whether to use cisco style VPLS.
cisco-style-id (integer; Default: 0) VPLS tunnel ID, used if cisco-style is set to yes.
comment (string; Default: ) Short description of the item
disable-running-check (yes | no; Default: no) Specifies whether to detect if interface is running or not. If set to no interface will always have running flag.
disabled (yes | no; Default: yes) Defines whether item is ignored or used. By default VPLS interface is disabled.
l2mtu (integer; Default: 1500)
mac-address (MAC; Default: )
mtu (integer; Default: 1500)
name (string; Default: ) Name of the interface
pw-type (raw-ethernet | tagged-ethernet; Default: raw-ethernet) Pseudowire type.
remote-peer (IP; Default: ) IP address of remote peer.
vpls-id (AsNum | AsIp; Default: ) Unique number that identifies VPLS tunnel.

Monitoring

Command /interface vpls monitor [id] will display current VPLS interface status

BGP VPLS

Sub-menu: /interface vpls bgp-vpls

List of BGP signaled VPLS instances. Configured instance makes router advertise VPLS BGP NLRI that advertises that particular router belongs to some VPLS.

Properties

Property Description
bridge (none | string; Default: none) If set to none VPLS interface is not added to bridge ports.
bridge-cost (integer; Default: 50)
bridge-horizon (none | integer; Default: none) If set to none bridge horizon will not be used.
comment (string; Default: ) Short description of the item
disabled (yes | no; Default: no) Defines whether item is ignored or used.
export-route-target (AsNum | AsIp; Default: ) Setting is used to tag BGP NLRI with one or more route targets.
import-route-target (AsNum | AsIp; Default: ) Setting is used to determine if BGP NLRI is related to particular VPLS, by comparing route targets received from BGP NLRI.
name (string; Default: )
route-distinguisher (AsNum | AsIp; Default: ) Specifies value that gets attached to VPLS NLRI so that receiving routers can distinguish advertisements that may otherwise look the same. This implies that unique route-distinguisher for every VPLS must be used. It is not necessary to use the same route distinguisher for some VPLS on all routers forming that VPLS as distinguisher is not used for determining if some BGP NLRI is related to particular VPLS (Route Target attribute is used for this), but it is mandatory to have different distinguishers for different VPLSes.
site-id (integer; Default: 1) Unique site identifier. Each site must have unique site-id.

Cisco Style BGP VPLS

Sub-menu: /interface cisco-bgp-vpls


Properties

Property Description
bridge (none | string; Default: none) If set to none VPLS interface is not added to bridge ports.
bridge-cost (integer; Default: 50)
bridge-horizon (none | integer; Default: none) If set to none bridge horizon will not be used.
comment (string; Default: ) Short description of the item
disabled (yes | no; Default: no) Defines whether item is ignored or used.
export-route-target (AsNum | AsIp; Default: ) Setting is used to tag BGP NLRI with one or more route targets.
import-route-target (AsNum | AsIp; Default: ) Setting is used to determine if BGP NLRI is related to particular VPLS, by comparing route targets received from BGP NLRI.
l2router-id (IP; Default: 0.0.0.0)
name (string; Default: )
route-distinguisher (AsNum | AsIp; Default: ) Specifies value that gets attached to VPLS NLRI so that receiving routers can distinguish advertisements that may otherwise look the same. This implies that unique route-distinguisher for every VPLS must be used. It is not necessary to use the same route distinguisher for some VPLS on all routers forming that VPLS as distinguisher is not used for determining if some BGP NLRI is related to particular VPLS (Route Target attribute is used for this), but it is mandatory to have different distinguishers for different VPLSes.
vpls-id (integer; Default: ) Unique number that identifies VPLS tunnel.
