Neutron Interface issue.

Hi,

I am new to the neutron. We have configured neutron on the dedicated node and won't able to give IP to instance. It is showing the IP in the networking option in instance details. When we log into the instance it is not showing any IP under instances. We have found that some of the interfaces showing down. Please check and suggest.

root@network:/var/log/neutron# ip a | grep state 1: lo: <loopback,up,lower_up> mtu 65536 qdisc noqueue state UNKNOWN 2: eth0: <broadcast,multicast,up,lower_up> mtu 1500 qdisc mq state UP qlen 1000 3: eth1: <broadcast,multicast> mtu 1500 qdisc noop state DOWN qlen 1000 4: eth2: <broadcast,multicast,up,lower_up> mtu 1500 qdisc mq state UP qlen 1000 5: eth3: <broadcast,multicast,up,lower_up> mtu 1500 qdisc pfifo_fast state UP qlen 1000 6: ovs-system: <broadcast,multicast> mtu 1500 qdisc noop state DOWN 7: br-int: <broadcast,up,lower_up> mtu 1500 qdisc noqueue state UNKNOWN 8: br-ex: <broadcast,up,lower_up> mtu 1500 qdisc noqueue state UNKNOWN 9: br-eth1: <broadcast,up,lower_up> mtu 1500 qdisc noqueue state UNKNOWN 37: phy-br-eth1: <broadcast,multicast,up,lower_up> mtu 1500 qdisc pfifo_fast state UP qlen 1000 38: int-br-eth1: <broadcast,multicast,up,lower_up> mtu 1500 qdisc pfifo_fast state UP qlen 1000
