Hi venkat,
lsr-loadbalancing lbl-ip aplicailable only for IPv4/IPv6 traffic, not
for epipe and vpls if you are speaking about P-P link.
Also, this feature depends on HW and SW. Not all sw versions support it
in mode "b" and on IOM 1&2 .
You have to check ALU doc carefully )
If you have epipe or vpls traffic on P-P link (ethernet header after
MPLS) then only solution to spray packets better is entropy label.
