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

going on very limited information here ... I assume you are trying to use eth1 as the interface in the bridge br-eth1, as part of a provider network mappings config. If so, then eth1 needs to be UP.
