Date: Tue, 17 Dec 2013 11:06:50 +0800 [thread overview]
Message-ID: <52AFBFCA.4060401@huawei.com> (raw)
Hi,
The bug came out by this:
1.ifconfig eth0:1 192.168.0.1
2.route add default gw 192.168.0.1
3.ifconfig eth0:1 172.168.0.1
4.route table is:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default 192.168.0.1 0.0.0.0 UG 0 0 0 eth0
default 128.5.130.254 0.0.0.0 UG 0 0 0 eth0
loopback * 255.0.0.0 U 0 0 0 lo
128.5.130.0 * 255.255.255.0 U 0 0 0 eth0
link-local * 255.255.0.0 U 0 0 0 eth0
172.168.0.0 * 255.255.0.0 U 0 0 0 eth0
Notice that,192.168.0.1 should be deleted because eth0:1's IP had been changed.
This bug seems to be long time exist.I test on kernel version 2.6.32 and 3.0.13,they both have the question.
