System Requirements

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

• JUNOS Release 6.0 or later for CCC, TCC, and Layer 2.5 VPN support on T-series platforms
• JUNOS Release 5.6 or later for proxy Address Resolution Protocol (ARP) functionality in Ethernet TCC and extended VLAN TCC networks on M-series routers
• JUNOS Release 5.4 or later for Ethernet TCC and extended VLAN TCC interface encapsulation types on M-series routers
• JUNOS Release 5.2 or later for PPP TCC, Cisco HDLC TCC, ATM TCC, and Frame Relay TCC interface encapsulation types on M-series routers
• Any Gigabit Ethernet or Fast Ethernet PIC for Ethernet TCC and extended VLAN TCC interface encapsulation types (except the Fast Ethernet 48-port PIC)
• Any combination of three Juniper Networks M-series or T-series Internet platforms for TCC or five platforms for Layer 2.5 VPNs or Layer 2.5 circuits.
