For which routes does LDP advertise a label binding?

For which routes does LDP advertise a label binding?

A.
All routes in the routing table

B.
Only the IGP and BGP routes in the routing table

C.
Only the BGP routes in the routing table

D.
Only the IGP routes in the routing table

Explanation:
LDP can only do bindings for IGP learned routes. If the route is learned from BGP, BGP has to do
the label binding. For CCIE R&S you don’t need to worry about using BGP for label distribution, as
this is used for Inter-AS MPLS L3VPN scenarios. If you change your setup so the routes are
learned from IGP instead of BGP they will have labels.
