Installation software could make this easy.  It could either prompt
the user to type in the address on a sticker then enumerate all
interfaces on the system and attempt to contact the router on each NIC.

Another possibility is that it could enumerate all the interfaces,
then use the IPv6 link-local scope all routers multicast (ff02::2) to
enumerate a list of routers found on each link, sort them and/or
filter them by ethernet OUI, and present a list of choices for the
user to click on to configure the router.  The user could also easily
match the enet address on a little slip of paper or sticker on the
router to this list, or through some initial settings on the router
which allow info to be pulled from it somehow, present a list of
unconfigured routers, etc, etc.

Point is, I can imagine a lot of ways this could be made user-proof
via software/firmware combination that requires no advanced networking
knowledge.
