Virtual private LAN service (VPLS) is a telecom carrier -provided service that makes it possible for customers to create a logical local area network (LAN) structure between geographically separate sites. All services in a VPLS appear to be on the same LAN, regardless of location.
Edward Buck is the Vice President of Technology and Service delivery at VPLS. Ed’s executive responsibility includes the design, delivery, maintenance, operations and support of all Evocative services. Prior to joining VPLS, Ed was a VP at UnitedLayer, a San Francisco based Colocation and Hosting Company. Linux bridge performs function of dot1q tag rewrite in order traffic with appropriate tag comes to VPLS. So our test topology looks like as follows: The configuration for our devices looks as follows: Virtual private LAN service (VPLS) enables one to connect local area networks (LANs) over the Internet, so that they appear to subscribers like a single Ethernet LAN. A VPLS uses MPLS to create the appearance of a virtual private network (VPN) at each subscriber location. Virtual Private Networks (VPNs) have evolved conciderably. Jun 22, 2014 · Building out virtual private lan services using GNS3 and a CSR1000v (free). VPLS allows for multipoint layer 2 MPLS WAN allowing a service provider to provide a full mesh layer 2 wan option to Dec 26, 2010 · VPLS provides Ethernet interface to users over the boundaries of LAN and WAN for customer and service provider. All services in VPLS is same as LAN services. Summary: (1) MPLS is a switching protocol considered to lie in between Layer 2 and Layer 3 in OSI Model. (2) MPLS is a technology for switching and VPLS is one of the services which run on Jan 11, 2015 · root@j40> show route forwarding-table family vpls Routing table: vpn-b.vpls VPLS: Destination Type RtRef Next hop Type Index NhRef Netif default perm 0 rjct 587 1 ge-0/0/3.803 user 0 comp 561 2 lsi.1048576 user 0 comp 593 2 00:0c:29:37:61:a2/48 dynm 0 ucst 559 3 ge-0/0/3.803 -- OUR MAC (J39) 00:0c:29:c3:b3:f4/48 dynm 0 indr 262142 4 -- REMOTE
Whereas a VPLS network is really more like a scalpel. You have a very, very specific thing that you’re trying to accomplish. You have to be relatively an expert to do it. So one of the biggest differences between global MPLS and global VPLS networks is that typically the customers who buy Layer 2 network have in-house BGP expertise.

The mac-move feature is useful to protect against undetected loops in your VPLS topology as well as the presence of duplicate MACs in a VPLS service. For example, if two clients in the VPLS have the same MAC address, the VPLS will experience a high re-learn rate for the MAC and will shut down the SAP or spoke SDP when the threshold is exceeded. What is MPLS: What you need to know about multi-protocol What is MPLS: What you need to know about multi-protocol label switchinig Multi-protocol label switching is a way to insure reliable connections for real-time applications, but it's expensive lan - Pros and cons of using VPLS instead of using MPLS VPLS can be used when you want to extend your layer-2 topology over multiple sites.
