Thanks James,

I could figure out and resolved it by disabling port security.

Hi Navdeep,

To get this to work, you will need to disable port security on the B device’s ports, or at a minimum, modify the allowed-address-pairs on the port to allow the traffic out towards C. Disabling port security is typically the way to go about satisfying this particular use case.

Subject: [Openstack] Routing in connected VMs

Dear all,


I am trying to create a network chain manually of VMs in openstack by entering the routing table entries in the machines. However, it doesn’t seems to work.
The network between the VMs is VLAN network on top of provider network.

Scenario is like : A-->B-->C

I have enabled the IP forwarding on the node B but I am not able to ping from A to C. ICMP echo requests are not reaching C.
I am able to ping from B to A and B to C. Please if someone could help in this regard.


Best Regards,
Navdeep
