在 Debian 接口文件中添加两个默认网关

nix*_*win 10 networking routing debian

这是我的接口文件:

auto eth0
iface eth0 inet static
   address 192.168.1.10
   netmask 255.255.255.0
   gateway 192.168.1.1

auto eth1
iface eth1 inet static
   address 192.168.2.10
   netmask 255.255.255.0
   gateway 192.168.2.1

如果我重新启动网络守护进程,我会收到此错误:eth1 is not up. 我想要两个默认网关来实现这里问题的已接受答案中提到的内容。我的路由表应该是这样的:

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         192.168.1.1     0.0.0.0         UG    0      0        0 eth0
default         192.168.2.1     0.0.0.0         UG    0      0        0 eth1
192.168.1.0     *               255.255.255.0   U     0      0        0 eth0
192.168.2.0     *               255.255.255.0   U     0      0        0 eth1

我通过使用ifconfigroute add default gw命令得到了上表。但我想用/etc/network/interfaces文件来做。我该怎么做?

更新1:

iface eth0 inet static
    address 192.168.1.10
    netmask 255.255.255.0
    up ip route del 192.168.1.0/24
    post-up ip route add 192.168.1.0/24 dev eth0 metric 1
    up route add default gw 192.168.1.1 metric 1

这个 /etc/network/interfaces 在 2.6.32-40 Ubuntu 10.04 LTS 上对我有用:

auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
    address 192.168.1.10
    netmask 255.255.255.0
    network 192.168.1.0
    broadcast 192.168.1.254
    post-up route add default gw 192.168.1.1 metric 1
    pre-down route del default gw 192.168.1.1

auto eth1
iface eth1 inet static
    address 192.168.2.10
    netmask 255.255.255.0
    network 192.168.2.0
    broadcast 192.168.2.254
    post-up route add default gw 192.168.2.1 metric 2
    pre-down route del default gw 192.168.2.1

我得到两个默认路由:

注意指标。我明白你的问题了吗?
