Hi,
We have two stacks of ex4200 switches (JunOS [12.3R6.6]). Between this stacks organized two L2-channels.
I need to load-balance CCC MPLS-traffic on these two L2-channles. But why MPLS-traffic only goes in one of the channels (through ae9.0)?
From the last table ("verify routing table family mpls") seen that only the traffic passes through the interface ae9.0, but where the interface ae.10?
Why no load-balancing between ae9.0 and ae10.0?
And will traffic passes through the interace ae10.0 if ae9.0 is fail?
