    Release Information

    Statement introduced in Junos OS Release 12.3 for T4000 Core Routers with Type 5 FPCs.

    Statement introduced in Junos OS Release 15.1F3 and 16.1R2 for PTX5000 routers with third-generation FPCs.

    Statement introduced in Junos OS Release 15.1F6 and 16.1R2 for PTX3000 routers with third-generation FPCs.

    Statement introduced in Junos OS Release 17.3R1 for PTX1000 routers.

    Description

    PTX1000, PTX3000 and PTX5000 Routers—When you configure enhanced-mode on PTX series routers, the following features are enabled on the router:

    • Filter-based generic routing encapsulation (GRE) for IPV4 and IPV6 tunneling.
    • promote gre-key statement for configuring gre-key as one of the matches in a filter.
    • promote dscp under family inet, and promote traffic-class under family inet6 statements for configuring these as one of the matches in a filter. (Added in Junos OS 17.1 for all PTX Series routers with third-generation FPCs.)
    • gtp-tunnel-endpoint-identifier statement for including hash calculation for IPv4 or IPv6 packets in the GPRS tunneling protocol–Tunnel end point ID (GTP-TEID) field hash calculations.
    • Wider configuration range for Bidirectional Forwarding Detection (BFD) protocol intervals.
    • Support for up to two million routes per chassis.
    • Support for Layer 3 VPN. The vrf-table-label statement is supported. (Added in Junos OS 15.1F5 for PTX5000 routers.)
    • Support for destination class usage (DCU) and source class usage (SCU) accounting. (Added in Junos OS 15.1F5 for PTX5000 routers.)

    Note:

    • When you configure the enhanced-mode statement, only third-generation FPCs are allowed to be powered on. All other FPCs are powered off and cannot be brought online.
    • When you do not configure the enhanced-mode statement, third-generation FPCs do not support the advanced features in the preceding list. Third-generation FPC only provide the same functionality as the first-generation and second-generation FPCs.
    • After you configure the enhanced-mode statement and commit the configuration, the router must reboot.

    T4000 Routers—When you configure enhanced-mode on T4000 routers, improved virtual private LAN service (VPLS) MAC address learning by supporting up to 262,143 MAC addresses per VPLS routing instance is enabled.

    Note:

    • The enhanced-mode statement supports up to 262,143 MAC addresses per VPLS routing instance. However, the MAC address learning limit for each interface remains the same (that is, 65,535 MAC addresses).
    • After you configure the enhanced-mode statement and committing the configuration, you receive a warning message that prompts you to reboot the router. You must reboot the router and then modify the size of the VPLS MAC address table; otherwise, the improved VPLS MAC address learning does not take effect.
    • When the T4000 router reboots after the enhanced-mode statement is configured, only the T4000 Type 5 FPCs are online while the remaining FPCs are offline.

    Default

    PTX Series Routers—By default, the enhanced-mode statement is disabled.

    T4000 Routers—By default, the improved VPLS MAC address learning feature is disabled.
