enhanced-mode (Network Services)
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.
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.)
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.
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.
PTX Series Routers—By default, the enhanced-mode statement is disabled.
T4000 Routers—By default, the improved VPLS MAC address learning feature is disabled.
