128k vMembers and 96k ARP and ND entries when using enhanced convergence in MC-LAG

The number of vmembers has increased to 128k, and the number of ARP and ND entries has increased to 96k. This increased scale is supported only when you enable the enhanced-convergence statement. Enhanced convergence improves Layer 2 and Layer 3 convergence time during multichassis aggregated Ethernet (MC-AE) link failures and restoration scenarios. If you have configured an IRB interface over an MC-AE interface that has enhanced convergence enabled, then you must configure enhanced convergence on the IRB interface as well. Enhanced convergence must be enabled for both Layer 2 and Layer 3 interfaces. To configure enhanced convergence, enable the enhanced-convergence statement at the [edit interfaces ae unit-number aggregated-ether-options mc-ae] at the Junos OS CLI hierarchy. To configure enhanced convergence on an IRB interface, enable the enhanced-convergence statement at the [edit interfaces irb unit unit-number] at the Junos OS CLI hierarchy.
