Release Information

Statement introduced in Junos OS Release 15.1R1.

Statement introduced in Junos OS Release 15.1X53-D60 for the QFX Series.

Description

Note

On EX9200 and QFX10000 switches, enhanced convergence is applicable for unicast traffic only—for example, when a MAC address is learned over an MC-AE interface, or an ARP entry is resolved over an MC-AE interface.

Note

Enhanced convergence is not supported on QFX5100, QFX5110, QFX5120, QFX5200-48Y, QFX5200-32C, and QFX5210-64C switches.

Improves Layer 2 and Layer 3 convergence time when a multichassis aggregated Ethernet (MC-AE) link goes down or comes up in a bridge domain or VLAN. Convergence time is improved because the traffic on the MC-AE interface is switched to the interchassis link (ICL) without waiting for a MAC address update.

If you have configured an IRB interface over an MC-AE interface that has enhanced convergences 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.
