How-To: Build a service provider network with a single Juniper Networks box--Part 3 # VPLS with BGP Signaling

by Super Contributor on ‎05-09-2017 07:56 AM (3,692 Views)

Hi Folks,

 

This paper is in continuation of my previous series of articles starting with the article titled "How-To: Build a service provider network with a single Juniper Networks box"

 

Topology Covered in this Article: Virtual private LAN service (VPLS) with BGP Signaling

 

Earlier, I helped you to build and understand the below topologies,

 

Part 1: MPLS L3VPN topology with IGP as OSPF and RSVP LSP for MPLS. There were direct MP-iBGP peering betwee...

 

Part 2: We introduced route-reflectors in the MPLS L3VPN topology with IGP as OSPF and RSVP LSP for MPLS.

 

Today, I would love to introduce to VPLS with BGP Signaling. Virtual private LAN service (VPLS) is an Ethernet-based point-to-multipoint Layer 2 VPN. It allows you to connect geographically dispersed Ethernet LAN sites to each other across an MPLS backbone. For customers who implement VPLS, all sites appear to be in the same Ethernet LAN even though traffic travels across the service provider's network.

 

VPLS, in its implementation and configuration, has much in common with an MPLS Layer 2 VPN. In a VPLS topology, a packet originating within a customer’s network is sent first to a customer edge (CE) device (for example, a router or Ethernet switch). It is then sent to a provider edge (PE) router within the service provider’s network. The packet traverses the service provider’s network over an MPLS label-switched path (LSP). It arrives at the egress PE router, which then forwards the traffic to the CE device at the destination customer site.

 

The difference is that for VPLS, packets can traverse the service provider’s network in point-to-multipoint fashion, meaning that a packet originating from a CE device can be broadcast to all the PE routers participating in a VPLS routing instance. In contrast, a Layer 2 VPN forwards packets in point-to-point fashion only. The paths carrying VPLS traffic between each PE router participating in a routing instance are signaled using BGP.

 

An important element of a VPLS instance is the signaling protocol. You can configure BGP signaling, LDP signaling, or both BGP and LDP signaling in a VPLS instance.

 

Theme: I will help you in building a basic service provider network with a single box! All you need is a single box with 4 physical loops to build a VPLS end-to-end Domain.

You can also use a virtual vMX box deployed in ESXi or KVM with a virtual loop!

 

Requirement:

Operating system: Junos OS Release 9.3 or higher

Box: EX Series, M Series, MX Series, PTX Series, T Series [any box that supports logical systems]

Interconnecting the logical systems can be achieved with lt interface [logical tunnel] or with physical interfaces.

 

Interfaces Supported: Ethernet Interfaces ge/xe that supports 802.1Q VLAN

    +----------------------------+

 

 

Steps:

Make 4 Physical Loop of physical interfaces in the box [4 loops – 8 interfaces].

Copy the following configuration template to a word editor and replace the strings interface1/2/3/4/5/6/7/8 with the actual interfaces you have looped.

Load the configuration to the box with “load merge terminal relative”.

 

Topology:

This is a VPLS topology with IGP as OSPF and RSVP LSP for MPLS. There are MP-iBGP peering between r1/r5 [PE] to r4 [RR].
