[Users] How to configure a server to use multiple subnets/gateways

[Jean-Marc Pigeon]

Bonjour Rene C,

My config:

ifcfg-br0
#definition Bridge interface
DEVICE=br0
ONBOOT=yes
TYPE=Bridge
BOOTPROTO=static
IPADDR=HOST IP number
NETMASK=255.255.255.224  #(My HOST SUBNET MASK)
IPV6INIT=yes
IPV6ADDR=PP:XX:.....YY:ZZ

ifcfg-br0:brgd
DEVICE=br0:brgd
ONBOOT=yes
TYPE=Bridge
BOOTPROTO=static
IPADDR=192.0.2.1
NETMASK=255.255.255.255
#to avoid checking for already set IP
ARPCHECK=no

I am using Quagga(RIP) to transparently route (and displace) VPS IP among HOST
such the VPS can be "somewhere" within Hardware cloud. (then VPS
can be set with an IP unrelated to HOST).

Hoping that help.
Contact me privately if I can help.
