System Requirements

To implement VPLS, your system must meet these minimum requirements:

• JUNOS Release 9.1 or later for nonstop active routing (NSR), VPLS ping on M120, M320, and MX-series routers, and automatic site selection for BGP-signaled VPLS
• JUNOS Release 9.0 or later for Virtual Spanning Tree Protocol (VSTP) support, 802.1p classification in Bridged Ethernet over ATM mode support, interworking between LDP and BGP signaling in a VPLS instance, and Layer 2 VPLS filters for MX960 routers
• JUNOS Release 8.4 or later for VPLS with LDP signaling. Also, integrated routing and bridging (IRB) is supported starting in this release
• JUNOS Release 8.3 or later for point-to-multipoint LSP support on VPLS
• JUNOS Release 8.2 or later for VPLS support on MX-series routing platform, VPLS graceful Routing Engine switchover (GRES) support, and VPLS support on Gigabit Ethernet IQ2 aggregated Ethernet interfaces
• JUNOS Release 7.6 or later for VPLS support on LSI logical interfaces
• JUNOS Release 7.5 or later for multihoming a CE router to multiple PE routers
• JUNOS Release 7.3 or later for VPLS per-packet load balancing, support for limiting MAC address learning per interface in a VPLS domain, and migration to the VPLS and Layer 2 VPN signaling statement at the [edit protocols bgp groups group-name family l2vpn] hierarchy level
• JUNOS Release 6.4 or later to implement Ethernet VPLS over ATM LLC interface encapsulation on T-series and M320 routing platforms, to select the tunnel-enabled PICs that provide virtual ports for VPLS operation, and to issue the show vpls statistics command
• JUNOS Release 6.3 or later to clear MAC addresses from the VPLS table and to modify VPLS table timeout intervals
• JUNOS Release 6.2 or later for VPLS class of service (CoS), VPLS graceful restart, VPLS interinstance bridging and routing, VPLS source and destination MAC address accounting, VPLS virtual port support on the Adaptive Services PIC for M-series routers, and general VPLS support for T-series and M320 routing platforms
• JUNOS Release 6.1 or later for VPLS policers and filters
• JUNOS Release 6.0 or later for Ethernet VPLS over ATM LLC interface encapsulation on M-series routers
• JUNOS Release 5.7 or later for VPLS with BGP signaling and Ethernet VPLS, VLAN VPLS, and extended VLAN VPLS interface encapsulations
• Two Juniper Networks M-series (except the M160 router), MX-series, T-series, or TX Matrix routing platforms for the provider edge (PE)
• On M-series and T-series routing platforms, one Adaptive Services PIC, Link Services PIC, or Tunnel Services PIC per routing platform to create VPLS virtual ports on vt interfaces
• On M-series and T-series routing platforms, one Fast Ethernet or Gigabit Ethernet PIC per routing platform (from this list):
  • 4-port Fast Ethernet PIC with 10/100 Base-TX interfaces
  • 1-port, 2-port, or 10-port Gigabit Ethernet PIC
  • 4-port, quad-wide Gigabit Ethernet PIC
  • 1- and 2-port Gigabit Ethernet Intelligent Queuing (IQ) PIC
  • 4- and 8-port Gigabit Ethernet IQ2 PIC with small form-factor pluggable transceivers (SFPs)
  • 1-, 2-, and 4-port Gigabit Ethernet PIC with SFPs
  • 1-port 10-Gigabit Ethernet PIC
