Initialization delay timer feature support on LAG interfaces

You can configure an initialization delay timer value on link aggregation group (LAG) interfaces. When a standby multichassis aggregated Ethernet (MC-AE) interface reboots to come up in active-active MC-AE mode, the Link Aggregation Control Protocol (LACP) protocol comes up faster than the Layer 3 protocols. As soon as LACP comes up, the interface is UP and starts receiving traffic from the neighboring interfaces. In absence of the routing information, the traffic received on the interface is dropped, causing traffic loss. The initialization delay timer, when configured, delays the MC-AE node from coming UP for a specified amount of time. This gives the Layer 3 protocols time to converge on the interface and prevent traffic loss. To configure the initialization delay timer on an MC-AE interface, use the init-delay-timer statement at the [edit interfaces ae-interface-name aggregated-ether-options mc-ae] hierarchy level.
