The host machine is CentOS 5 In one network goes vlan-2 and with the numbers 11 (192.168.1.0/29) and 17 (192.168.2.128/28) And each vlan its own address of the router and use a default route fails. When set up had to distort the way: 1. The route started by default 192.168.1.1 2. And for the second vlan in /etc/iproute2/rt_tables added 201 vlan17 and /etc/sysconfig/network-scripts/route-eth0.17 prescribed here is 192.168.1.2.128/28 dev eth0.17 table vlan17 default via 192.168.1.2.129 table vlan17 With this config, the host machine for both addresses ping ok But virtualki on the 17th when you create a vlan not ping from vneshki. But if they start to ping rebutnut and pinganut with the host machine. But not for long. After some time again to fall off. And each start virtualki waddle this error arpsend: 192.168.1.4 is detected on another computer : 00:11:20:f9:b7:01 vps-net_add WARNING: arpsend -c 1 -w 1 -D -e 192.168.1.4 eth0.17 FAILED

And hence the problem emerged. Help please.
Hello, sorry but I had some difficulties to understand your post. Nevertheless, I'd like to make some notes: - here is a very useful article which may be used when configuring VLANs. http://en.gentoo-wiki.com/wiki/OpenVZ_VLAN - Quote: arpsend: 192.168.1.4 is detected on another computer : 00:11:20:f9:b7:01 vps-net_add WARNING: arpsend -c 1 -w 1 -D -e 192.168.1.4 eth0.17 FAILED Isn't this message clear? There is another computer 00:11:20:f9:b7:01 which has this ip address. - Quote: After some time again to fall off. It seems that information which is intended to be distributed via arpsend becomes out of date.
