The use of the subclass spawning mechanism is not restricted to relay
agent options - this particular example is given only because it is a
fairly straightforward one.
.SH COMBINING MATCH, MATCH IF AND SPAWN WITH
.PP
In some cases, it may be useful to use one expression to assign a
client to a particular class, and a second expression to put it into a
subclass of that class. This can be done by combining the \fBmatch
if\fR and \fBspawn with\fR statements, or the \fBmatch if\fR and
\fBmatch\fR statements. For example:
.PP
.nf
class "jr-cable-modems" {
match if option dhcp-vendor-identifier = "jrcm";
spawn with option agent.circuit-id;
lease limit 4;
}
class "dv-dsl-modems" {
match if opton dhcp-vendor-identifier = "dvdsl";
spawn with option agent.circuit-id;
lease limit 16;
}
.fi
.PP
This allows you to have two classes that both have the same \fBspawn
with\fR expression without getting the clients in the two classes
confused with each other.

The DHCP server has the ability to dynamically update the Domain Name
