default gateway does not set with vlan

**alexhemp** · August 25th, 2016

I've got ubuntu 16.04.1 server with two interfaces, each of them connected to different member of switch stack.

/etc/network/interfaces

Code:

auto lo
iface lo inet loopback

auto eno1
iface eno1 inet manual
    bond-master bond0

auto eno2
iface eno2 inet manual
    bond-master bond0

auto bond0
iface bond0 inet manual
    bond-slaves eno1 eno2
    bond-mode 802.3ad
    bond-miimon 100
    bond-lacp-rate 1

auto vlan2
iface vlan2 inet static
    vlan_raw_device bond0
    address 192.168.0.10
    netmask 255.255.255.0
    gateway 192.168.0.1
    dns-nameservers 192.168.0.1 192.168.0.2
    dns-search local

After reboot I expect 192.168.0.1 as default gw in routing table but it's not

Code:

root@ubuntu:/# netstat -rn
Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
192.168.0.0   0.0.0.0         255.255.255.0   U         0 0          0 vlan2

After executing "route add default gw 192.168.0.1" everything works fine

I've temporary solved the problem by adding this command to /etc/rc.local but it should work as expected. Same config on 14.04.04 works fine.
