[Dibbler] Server questions

[Daniel Barboza]

"Of course, the ultimate solution would be that client remembers its
address between exections (this is missing) and ask server for that
address (this is done and working as server honors client's hints).
Anyway, I have filed a bug to this issue:
http://klub.com.pl/cgi-bin/bugzilla/show_bug.cgi?id4"

Thank you. As soon as this is fixed on CVS I'm gonna need it :)

"Anyway, are you sure you really want to share the same address pool over
several interfaces? How are you going to configure routing in your
network?"

The problem of routing is addressed by setting RSvP paths through routers
for each node on the subnets. This is not a serious issue.

The case is: if there's more than one relay that connects to the same
server, and it occurs that they relays subnetworks with the same prefix, I
would like that a client that gets an address at one relay agent should be
able to retain the same address when it pass to the other subnetwork with
other relay agent (a handover actually).

Once the same pool on the server cannot have more than one interface-id
assigned, in other words, it cannot assign addresses to more than one relay
agent, I've imagined a workaround at this problem by sharing the same
address pool on more than one interface declarations.

But as long as a client can have the same previous address by the server, I
think that the server will provide the address asked by the client if this
address is valid on the address pool and not used by other nodes. This is
enough for me.

Thanks a lot,

Daniel
