[GTALUG] 2 networks under ip (iproute2)

[Walter Dnes]

  This is frustrating, because it works for me under ifconfig, but not
under ip (iproute2).  I have 3 devices in this scenario...

* my desktop PC 192.168.123.251/29
* an HDHomerun TV tuner that comes up in the 169.254.0.0/16 block
* the ADSL router/modem at 192.168.123.254/29 to which the PC and the
  tuner are connected.

  I'm trying to get my desktop PC to talk to the TV tuner using ip.
What am I doing wrong in the following set of commands?

ip address flush dev eth0
ip link set eth0 down
ip link set eth0 up
ip address add 192.168.123.251/29 dev eth0
ip route add default via 192.168.123.254
ip address add 169.254.1.1/16 dev eth0
ip route delete 169.254.0.0/16 dev eth0
ip route add 169.254.0.0/16 via 192.168.123.254
ip address show
ip route show

  The ouput from the 2 "show" commands is...
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default
