Questions regarding infinite leases and T1/T2 timers

["Michael J. Lewis" <[e-mail]>]

I've just finished looking at a vendor DHCP server that for a 
manual entry (map an IP address to a specific MAC address), returns an 
infinite lease and values for T1 and T2 that map to the appropriate 
values for the normal lease on the subnet.  My client sees the infinite 
lease and proceeds to ignore the T1/T2 values, thereby failing to renew 
the lease and pick up any changed configuration parameters.

This unexpected scenario has raised two questions regarding the DHCP 
protocol specifications.

	1.  Should the server provide T1/T2 times on an infinite lease?
		(Or is it possible to have an infinite lease that 
		requires a client to go through the renewal process?)
	2.  If such options are included in a REQUEST packet, can the
		client ignore them?

I looked through the draft DHCP specifications but there is very little 
regarding infinite leases and whether the timers apply.  It would seem 
that one or both of the implementations are in error here but I did not 
want to call either vendor until I had some consensus as to what meets 
the specifications.

Thanks for your help.
