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

Enable improved virtual private LAN service (VPLS) MAC address learning by supporting up to 262,143 MAC addresses per VPLS routing instance.

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 commit your configuration, a warning message 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.

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