I am trying to understanding the use of TE extension of IGP in a MPLS
network. From my understanding, you need TE extension when you're doing
on-node path computation. However, since LSPs in today's MPLS network
are usually computed off-node (in software tool), why would the use of
TE extension be critical?

Appreciate if someone can shed some light on this question.

Thanks,
Hansen
