MPLS Layer 3 VPN Configuration

(Lazaros Agapides) #84

Hello NetRuso

Yes, the only thing that is necessary, in its most basic configuration, is the enabling of MPLS on the interfaces which connect PE1 and PE2 to the P router.

Can you be more specific as to what you’re having trouble with? Let us know so we can clarify it for you.

I hope this has been helpful!

Hi Rene,

Could you please explain VPLS and H-VPLS.

what is the difference between EVPN and VPLS. why EVPN is better than VPLS.

Thanks in advance

Hello Rahul

VPLS and H-VPLS are both technologies that use IP or MPLS networks to provide layer 2 connectivity between remote sites. This essentially allows dispersed sites to share a single Ethernet broadcast domain by connecting sites through what are known as pseudowires. This is a method of making L2 connections over an L3 infrastructure.

VPLS requires full mesh connectivity between sites, which is not very scalable. H-VPLS or Hierarchical VPLS is a method of allowing for scalability by dividing VPLS networks into two or three tiered hierarchical networks.

EVPN technologies provide similar services, but do so in different ways. The primary differences are:

  • Signalling
  • CE multihoming
  • MAC learning

More information about these differences can be found at the following links:
