It specifies addresses which might appear in the local peer's
route table as a next hop corresponding to a given remote peer.

See section 2.7, "LDP Identifiers and Next Hop Addresses" in
RFC 3036.

This is not specified and either may be used.  See section 4.2 of -

"http://www.ietf.org/internet-drafts/draft-ietf-mpls-cr-ldp-05.txt"

- and sections 4.3.2 and 4.3.3 of -

"http://www.ietf.org/internet-drafts/draft-ietf-mpls-rsvp-lsp-tunnel-08.txt"

for information on the types of 'addresses' that may appear in an
ER-Hop or ERO Subobject (respectively)...
