Create Tunnel,network,subnet,port and boot all VM's.<br/> 2.Create l3vpn and associate subnet ID from karaf<br/> Ex:<br/> vpnservice:configure-l3vpn -op create-l3-vpn --subnet-uuid 85aafd43-6c53-4d15-9806-a825d8b3cc2e --vpnid abcdabcd-1234-1234-1234-abcdabcdabcd --name testVpn1 --rd 200:1 --import-rts 200:1 --export-rts 200:1<br/> vpnservice:configure-l3vpn -op create-l3-vpn --subnet-uuid b8504eae-7684-438d-8fbb-a55beb625ab8 --vpnid abcdabcd-1234-1234-1234-abcdabcdabcd --name testVpn1 --rd 200:1 --import-rts 200:1 --export-rts 200:1<br/> 3. check ping works with all VM's across DPNs.<br/> 4. Delete VPN and recreate VPN using the same above ping.<br/> 5. Check ping behavior with all VM's across DPNs.</p> <p>Result:<br/> ping is not successful across VM.</p> <p>All the required logs(flows,groups and karaf logs attached</p> <p>Operating System: All<br/> Platform: All</p> VPNSERVICE-47
