agreed,

but wherever the "label switching starts" too,you have to do an L3 lookup..

take the case of a packet entring a VRF with multiple interfaces in the
VRF.(L3VPN)

how does one determine where to Label switch the packet to without doing an
L3 lookup?

atleast in the case of binding labels to P2P interfaces we have an advantage
of avoiding an L3 lookup at egress point.
