BOB My understanding that the term "IGP Label" within a context of BGP/MPLS VPN refer to the TOP label which could be distributed by LDP (between directly connected LDP peer ) or RSVP . This to differentiate between the MP-BGP lable which is distributed by MP-BGP ( the Bottom Label) . The TOP label need to be recognized by all LSR in the path , so either distributed by LDP (between directly connected LDP peer ) or RSVP . i guess that label distributed by targeted LDP (between non-directly LDP peer) should not be named as "IGP Label" ex: PWE3 signalling used LDP targetted LDP to advertised label not at all associated with IGP routes . In short , "IGP Label" could be read as "TOP Label" . The text in CSCO doc : "Within a single network, can use LDP or RSVP to distribute IGP labels" could be read as "Within a single network, can use LDP (between directly connected LDP Peer) or RSVP to distribute TOP labels ".
