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

<p class="MsoNormal">Hi Navdeep,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">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.</p>

<p class="MsoNormal"><span style="">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.</span></p>
<p class="MsoNormal"><span style="">The network between the VMs is VLAN network on top of provider network.

<p class="MsoNormal"><span style="">Scenario is like : A</span><span style=""><span style="font-family:Wingdings">à</span>B</span><span style=""><span style="font-family:Wingdings">à</span>C

<p class="MsoNormal"><span style="">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.
