Translational Cross-Connect and Layer 2.5 VPNs System Requirements
To implement TCC, your system must meet these minimum requirements:
Junos OS Release 10.1 or later for support of IS-IS and MPLS traffic over Layer 2.5 VPNs on MX Series routers.
Junos OS Release 8.3 or later for support of IS-IS and MPLS traffic over Layer 2.5 VPNs on T Series and M320 routers.
Junos OS Release 8.2 or later for support on M120 routers and MX Series routers
Junos OS Release 6.2 or later for CCC, TCC, and Layer 2.5 VPN support on M320 routers
Junos OS Release 6.0 or later for CCC, TCC, and Layer 2.5 VPN support on T Series routers
Junos OS 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 OS Release 5.4 or later for Ethernet TCC and extended VLAN TCC interface encapsulation types on M Series routers
Junos OS Release 5.2 or later for PPP TCC, Cisco HDLC TCC, ATM TCC, and Frame Relay TCC interface encapsulation types on M Series routers
Ethernet-based PICs to support Ethernet TCC and extended VLAN TCC interface encapsulation types, with the following exceptions:
All 8-port, 12-port, and 48-port Fast Ethernet PICs do not support TCC.
4-port Gigabit Ethernet PICs do not support extended VLAN TCC.
Any combination of three Juniper Networks M Series or T Series routers for TCC or five routers for Layer 2.5 VPNs or Layer 2.5 circuits
