EFFECT:

Ping test is FAILED from VM to Invisible IP which is hosted non-nexthop system.

DESCRIPTION:
Test Topology:
===============
N1-S1-VM1,N2-S2-VM3,N3-S3-VM5 on ComputeNode1 is connected to DPN1/ComputeNode1

N1-S1-VM2,N2-S2-VM4,N3-S3-VM6 on ComputeNode2 is connected to DPN2/ComputeNode2

CBA Controller Setup with 2SC's and 3PL's.

Build Used: sfi_beryllium-16.2.52.0.14
CSS Build : CSS3.0 Drop5 Black build (official release)

Steps To Reproduce:
===================
1. Bring up the Topology as mentioned above.
2. Create and configure VXLAN Tunnel between DPNs
3. Create Neutron network1,2,3/Subnets1,2,3/Ports1,2,3,4,5,6
4. Bring up NOVA VMs 1,2,3,4,5,6
5. Create L3vpn and associate N1 to L3VPN.

Create L3vpn:
http://10.183.254.195:8181/restconf/operations/neutronvpn:createL3VPN

{"input" : {
"l3vpn" : [

]
}
}

http://10.183.254.195:8080/restconf/operations/neutronvpn:associateNetworks

{
"input" :

}

6.Create a Router and associate the network2 and network3 to it.
neutron router-create Router1
neutron router-interface-add Router1 net2-snet2
neutron router-interface-add Router1 net3-snet3

7. Associate Router1 to L3VPN:

{"input" :

}
8.Create and bring up (Enterprise Network Host IP) eth0:1 interface on DPN1-VM3 with 20.0.0.150 (Invisible IP) and make sure 20.0.0.0/24 has a nexthop IP of DPN2 BR1 tunnel interface IP in "display fib"
9. Ping test is FAILED from VM5-DPN1(30.0.0.2) to 20.0.0.150 (Invisible IPs) which is hosted on non-nexthop

Expected Results:
Ping test should be PASSED even though inivisble IP is hosted non-nexthop for subnet route.(20.0.0.0/24)
