Hi Jakub Thanks, ok, if there is no different in vm point of view, then,
vrouter need arp proxy to say, hi vm, your gateway is here, send traffic to
me, i will help you to forward to destination, after vrouter receivce the
traffic, it will search its routing table, locate where is destination, OK,
then another question coming up , vrouter resolve MAC of destination VM, send
arp request? in openstack neutron, it is being resolved by L2pop. Sorry for
asking so many question.

there is not different from VMs point of view. It is same like standard L2
subnet:
root@server:~# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP
qlen 1000
link/ether 02:0f:db:4b:e7:ad brd ff:ff:ff:ff:ff:ff
inet 192.168.1.2/24 brd 192.168.10.255 scope global eth0
inet6 fe80::f:dbff:fe4b:e7ad/64 scope link
valid_lft forever preferred_lft forever
root@server:~# ip r
default via 192.168.1.1 dev eth0 metric 100
192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.2

| Hi jakub I have another question, since vrouter only have /32 routes,
when opencontrail integrate openstack neutron, there is one subnet in a network
, its cidr is 192.168.1.0/24 , now nova boot a instance called vm1 in that
network, then if you execute ifconfig in vm1, what is output you get ? Also
what is output of command ip route show ?
