padavan 怎样DHCP分配不同网关

cdpeng***

    最近主路由从OPENWRT换成PADAVAN,原来OPENWRT实现方式为：
主路由：192.168.100.1(开启DHCP)   旁路由：192.168.100.254（关闭DHCP）
修改vim /etc/dnsmasq.conf文件，添加以下代码：(tag:gf,3为新增分组GF 3为网关地址)（tag:gf,6为新增分组GF 6为DNS地址）


dhcp-option=tag:GF,3,192.168.100.254
dhcp-option=tag:GF,6,192.168.100.1
dhcp-host=fc:d9:08:89:f3:09,set:GF
dhcp-host=68:14:01:A3:0F:B1,set:GF
dhcp-host=b0:6e:bf:2c:ee:78,set:GF
dhcp-host=F4:B3:01:5F:40:47,set:GF





mac地址匹配则分配GF分组的网关和DNS






请问大佬们，PADAVAN的DHCP是否是DNSMASQ管理？怎么编写
下面为PADAVAN的DNSMASQ文件


user=nobody
resolv-file=/etc/resolv.conf
no-poll
bogus-priv
no-negcache
clear-on-reload
bind-dynamic
interface=br0
listen-address=192.168.100.1
min-port=4096
cache-size=1536
dns-forward-max=512
addn-hosts=/etc/storage/dnsmasq/hosts
servers-file=/tmp/dnsmasq.servers
dhcp-hostsfile=/etc/storage/dnsmasq/dhcp.conf
domain=lan
expand-hosts
dhcp-range=set:lan,192.168.100.2,192.168.100.244,255.255.255.0,86400
dhcp-option=tag:lan,3,192.168.100.1
dhcp-option=tag:lan,6,192.168.100.1
dhcp-option=tag:lan,15,lan
quiet-dhcp
enable-ra
quiet-ra
ra-param=br0,30,1800
dhcp-range=set:lan,::,constructor:br0,ra-stateless,ra-names,64,600
dhcp-option=tag:lan,option6:23,[::]
dhcp-option=tag:lan,option6:24,lan
dhcp-option=tag:lan,option6:32,600
quiet-dhcp6
dhcp-hostsfile=/etc/dnsmasq/dhcp
dhcp-leasefile=/tmp/dnsmasq.leases
dhcp-authoritative
conf-file=/etc/storage/dnsmasq/dnsmasq.conf


请问标红dhcp-option=tag:lan,15,lan   中的15是什么意思
