MPLS technology is evolving, with more services being offered using MPLS connectivity. Junos OS features are also evolving to implement these services on Juniper Networks routers.

 

The most common MPLS connectivity services include:

  • Virtual Private LAN Service (VPLS)
  • Layer 3 virtual private networks (VPNs)
  • Layer 2 circuits and Layer 2 VPNs

Layer 3 VPN service is a point-to-point Layer 3 VPN network built over the service provider’s MPLS transport network. This type of service is based on RFC 2547bis, BGP/MPLS IP VPNs.

This article provides answers to the most common questions about Layer 3 VPNs on Juniper Networks MX Series routers.

 

  1. Can I manually select the upstream multicast hop in NG-MPVN instead of having it default to the highest IP address?
  2. Is four-label push/pop for MPLS supported on Juniper Networks devices?
  3. What is the correct behavior for an NG-MVPN implementation?
  4. Which timer statements are supported for point-to-multipoint LSPs?
  5. How is composite next hop used in Layer 3 VPNs?
  6. Can multicast ping be used with a static IGMP join in Rosen MVPN?
  7. Is fast reroute supported in point-to-multipoint LSP?
