At present, I see no benefit for an ISATAP node to affiliate with
more than one ISATAP router. If any such benefits exist, I am sure
they will be identified by the design team studies. However, I think
it perfectly reasonable for a host to know about multiple *candidate*
ISATAP routers; even if it only affiliates with one at a time. (Sort
of like "Candidate Access Router discovery" in the Seamoby group).

Please check my recent submission entitled "Proposed Solutions for
ISATAP Operational Issues" under "Operational issue #5". You need to
cross reference this document against the isatap-05 document, which
you may need to pull from my webserver *again* if you are not seeing
a proper matchup with the solutions document. (I made a mistake
in the original posting and had to post a new version.)
