You have to rewrite the dhcp-parameter-request-list
if exists dhcp-parameter-request-list {
append dhcp-parameter-request-list 208,209;
}
or in this form ( i don't remember well )
if exists dhcp-parameter-request-list {
option dhcp-parameter-request-list = concat(option
dhcp-parameter-request-list,d0,d1);
}
Ps : however in the second form the 208 , 209 must be rewrited in
hexadecimal form : d0 and d1
I hope will help you
regards
Stephane
