System Requirements

To implement SCU, your system must meet these requirements:

• JUNOS Release 6.2 or later for IPv6 SCU.
• JUNOS Release 5.6 or later to use a source class or a destination class as a match condition in a firewall filter.
• JUNOS Release 5.4 or later for IPv4 SCU.
• Three Juniper Networks routing platforms for basic SCU and five routing platforms for SCU with Layer 3 VPNs. One routing platform containing an Internet Processor II (such as the M-series or T-series routing platforms) acts as a source class usage transit router, and the other routing platforms are used to generate traffic or participate in the Layer 3 VPN.
• A Tunnel Services PIC for SCU with Layer 3 VPNs.
