In your previous mail you wrote:
I think it would be useful for an SNMP manager (or possibly
other applications) within a site-local zone to be able to
determine which zone ID a zone-boundary router is using to
identify the manager's local site. Do we currently have a way
to do this? Is anyone working on something like this?
=> zone ID is local to the node then I think your proposal
should go (and get the same answer) with Jean-Luc's one (*).
A possible solution would be a new ICMP message that asks for
the remote host to return the zone ID indicated by the interface
on which the message was received. A message sent to a link-local
address would return a link-level zone ID; a message sent to a
site-local address would return the site-level zone ID.
=> ICMP name-lookups are supposed to address all these problems,
perhaps we have to add something in the I-D, but I believe we don't
need new ICMP message(s).
Thanks

PS: Jean-Luc Richier's problem: you'd like to discover the topology
of a network, you get the routing table from a router, look at gateway
fields of not-direct routes, they give the address of all the downstream
routers attached to the first target.
Problem: these addresses are in general (ie. there is no reason to not be :-)
link-local addresses then you can't use them as destination addresses for
SNMP queries.
Solution: use ICMP name-lookups in order to get a global address of a router.
Exactly what is needed is a proxy service for ICMP name-lookups,
PPS: MZAP (RFC 2776) of course can help and its to-come MIB will give
the perfect answer to your question.
