To implement TCC, your system
must meet these minimum requirements:
JUNOS Release 8.3 or later for support of IS-IS and MPLS
traffic over Layer 2.5 VPNs.
JUNOS Release 8.2 or later for support on M120 routers
and MX Series routers
JUNOS Release 6.2 or later for CCC, TCC, and Layer 2.5
VPN support on M320 routers
JUNOS Release 6.0 or later for CCC, TCC, and Layer 2.5
VPN support on T Series routers
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
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
