This works:
================= FAILSAFE MODE active ================
# ifconfig -a
eth0      Link encap:Ethernet  HWaddr 00:18:39:21:0D:AE  
          inet addr:192.168.1.1  Bcast:192.168.1.255  Mask:255.255.255.0
          inet6 addr: fe80::218:39ff:fe21:dae/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:8 errors:0 dropped:0 overruns:0 carrier:0

Ping to 192.168.1.1 answers, after pinging:
          RX packets:5 errors:0 dropped:0 overruns:0 frame:0
          TX packets:14 errors:0 dropped:0 overruns:0 carrier:0

This does not:

br-lan          7fff.001839210dae       no              eth0

Ping to neither 192.168.1.1 nor 192.168.0.10 does not answer.
