The techniques describe detecting connectivity failure of an aggregated interface. To monitor connectivity of the aggregated interface, a packet processor of a plurality of packet processors is set as a session master responsible for managing an active forwarding plane connectivity detection session with a peer session master node. The other local packet processors of the virtual network node are selected as session standby nodes that each have a passive forwarding plane connectivity detection session running to the peer session master node. If a session master node goes down (i.e., by link or node failure), one of the local session standby nodes may detect the failure and is set as a new session master node by activating its passive session having the same session parameters.

The techniques describe packet reordering for packets flowing on a new path in response to a change in internal forwarding paths in a network device. For example, a network device may dynamically change the selection of an internal forwarding path to achieve fabric path optimization ('OFP') or to ensure optimized load balancing. Packets forwarded on the new path are buffered such that the transmission of packets forwarded on the new path are delayed for a buffering time period of at least the time in which a packet is being sent from the source packet processor to the initial destination packet processor.
