Multiple Instances for Label Distribution Protocol System Requirements

To implement the multiple-instance LDP feature, your system must meet these minimum requirements:

• Junos OS Release 8.2 for support on MX Series routers.
• Junos OS Release 5.4 or later for support on M Series and T Series routers.
• Two Juniper Networks M Series, MX Series, or T Series routers for basic multiple-instance LDP; and a minimum of four Juniper Networks routers to act as PE routers in a carrier-of-carriers network.
