Description
Configure the router to signal the capability to push the flow label in the transmit direction to the provider edge (PE) router.
The flow-aware transport of pseudowires (FAT) flow labels enable load-balancing of MPLS packets across equal-cost multipath (ECMP) paths or link aggregation groups (LAGs) without the need for deep packet inspection of the payload. FAT flow labels can be used for LDP-signaled forwarding equivalence class (FEC 128 and FEC 129) pseudowires for virtual private LAN service (VPLS) and virtual private wire service (VPWS) networks.
Starting with Junos OS Release 16.1,
flow-label-transmitstatement is supported for BGP L2VPN and BGP VPLS.The
flow-label-transmitstatement is not supported in OAM CFM session over L2Circuit.
