есть centos с dhcp-3.0.5-23.el5_5.2.x86_64
на нем не работают option 249 и 121
в режиме отладки выдает вот это-
unknown option dhcp.ms-classless-static-routes

конфиг обычный:

default-lease-time 300;
max-lease-time 7200;
min-lease-time 300;
ddns-update-style none;
option domain-name "local.domain";
option domain-name-servers 192.168.1.11;
authoritative;
log-facility local7;
option ms-classless-static-routes code 249 = string;
option rfc3442-classless-static-routes code 121 = string;

subnet 192.168.1.0 netmask 255.255.255.0 {
    range 192.168.1.202 192.168.1.254;
    option routers 192.168.1.111;
    option subnet-mask 255.255.255.0;

    host atc    { hardware ethernet yy:yy:yy:yy:yy:yy; fixed-address 192.168.1.222; }
    host vm     { hardware ethernet zz:zz:zz:zz:zz:zz; fixed-address 192.168.1.204; }
}
если кто сталкивался с такой проблемой подскажите куда копать...
