Subject: Question re: P/NHOP field for unnumbered interfaces in GMPLS

According to rfc 3473:
 
The Hop Address and Logical Interface Handle fields are  used per standard
RSVP [RFC2205].
 
According to rfc 2205:
 
This object carries the IP address of the interface through which the last
RSVP-knowledgeable hop forwarded this message.  
 
But in the case of unnumbered interfaces, there is no such address. What
should go in this field? A router ID?
 
Thanks
