我正在设置一个带有多个以太网接口的Ubuntu Server 11.10机箱,这些接口是为了冗余而绑定的.我打算将它用作KVM主机,所以我需要一个网桥.
为此,我安装了ifenslave和bridge-utils,然后编写了我的/ etc / network / interfaces文件.相关部分如下：
- auto br0
- iface br0 inet static
- address 10.1.254.101
- netmask 255.255.255.0
- network 10.1.254.0
- broadcast 10.1.254.255
- gateway 10.1.254.50
- dns-nameservers 10.1.254.252
- bridge_ports bond0
- bridge_stp off
- iface bond0 inet manual
- bond-slaves eth0 eth3
- bond_mode balance-rr
- bond_miimon 100
不幸的是,这不是给我连接. ifup br0给我“无法将bond0添加到桥接br0：无效参数”,而ifdown br0给我“设备bond0不是br0的从属”.如果我修改我的interfaces文件以摆脱桥接,我有完全的连接 – 但我将需要桥.
这就是我如何配置Ubuntu 10.04 LTS系统以在绑定接口之上进行桥接：
- iface eth0 inet manual
- iface eth5 inet manual
- # eth0 & eth5 form bond0 for the x.y.z.0/25 subnet
- auto bond0
- iface bond0 inet static
- bond_miimon 100
- bond_mode active-backup
- bond_downdelay 200
- bond_updelay 200
- address x.y.z.35
- netmask 255.255.255.128
- network x.y.z.0
- post-up ifenslave bond0 eth0 eth5
- pre-down ifenslave -d bond0 eth0 eth5
- auto br0
- iface br0 inet static
- bridge_ports bond0
- address x.y.z.35
- netmask 255.255.255.128
- network x.y.z.0
- gateway x.y.z.126
