Obtendo “sem endereços IPv4” com o isc-dhcp-server e subinterfaces

Question

Eu tentei ambas as subinterfaces e a rota secundária de endereço IP e também não estou trabalhando para o isc-dhcp-server. Está se recusando a puxar o IP adequado. Eu estou usando Debian 8 Jessie e ISC-DHCP-SERVER 4.3.1.

Meu / etc / network / interfaces

## Corporate Network
auto eth0
allow-hotplug eth0
iface eth0 inet manual

## New Subnet
auto eth0:0
allow-hotplug eth0:0
iface eth0:0 inet static
    address 10.0.0.2
    gateway 10.0.0.1
    netmask 255.255.0.0
    dns-nameservers 127.0.0.1 10.0.0.3
    dns-search example.net
    dns-domain example.net

## Old Subnet
auto eth0:1
allow-hotplug eth0:1
iface eth0:1 inet static
    address 10.136.136.253
    netmask 255.255.255.0

Answer 1

Acabei encontrando a resposta em outro post. Os decodificadores de sub-rede no dhcpd.conf precisam ser agrupados em um decodificador de rede compartilhada.

shared-network vlan1 {
    subnet 10.0.0.0 netmask 255.255.0.0 {
        ....
    }

    subnet 10.136.136.0 netmask 255.255.255.0 {
        ....
    }
}
