Given a dual-homed server with:

  the following interfaces:

    eth0: address 192.168.3.13 netmask 255.255.255.0
    eth1: address 192.168.4.13 netmask 255.255.255.0

  and the following sub-interface:

    eth0:0 address 169.254.0.13 netmask 255.255.0.0

Is it possible to create an efficient bridge between
eth0:0 and eth1 for 169.254.*.* traffic only, while
giving my server applications visibility of all three
subnets?

If this is indeed possible, will server performance
be seriously degraded by non-169.254.*.* traffic on
either interface?

TIA,
 
Vincent Callanan
