members allow/deny question

[Duane Cox]

Here is a snip from my configuration.

My question is, is the specific "deny" needed?
What would happen if the "allow" pool was full, but another pool was 
available because there was no deny, assuming I deleted the "deny" 
statement?

shared-network LMC1A-WEST-CH5 {
        subnet 10.11.5.0 netmask 255.255.255.0 {
        }

        subnet 10.252.235.128 netmask 255.255.255.224 {
        }

        pool {
                failover peer "dhcp";
                deny known-clients;
                deny dynamic bootp clients;
                range 10.11.5.100 10.11.5.250;
                option routers 10.11.5.254;
                allow members of "IPTV";
        }

        pool {
                failover peer "dhcp";
                deny known-clients;
                deny dynamic bootp clients;
                range 10.252.235.130 10.252.235.158;
                option routers 10.252.235.129;
                deny members of "IPTV";
        }
}
