| Description |
|
I have created a topology with two routers connected to an external-network. each router is connected to two private networks, each private network has one subnet and two VMs. In addition, I have two compute nodes. I can see that one of the 4 router_interface flows is missing from table 19, on both computes, which causes ping for both vms on this network to fail. i'm attaching karaf log , ovs flows dump, and some of the karaf models. The missing router_interface flow has ip 71.0.0.49 and MAC fa:16:3e:c6:d9:1b. |

The root cause might be that ODL got an ARP request with srcip=router_interface_ip, and in the current code this will override the isSubnet entry on the router interface. If this is indeed the case, the following commit may solve this bug: |

Assuming my analysis above is correct, this has probably been solved by https://git.opendaylight.org/gerrit/#/c/48054/ If this somehow reoccurs (couldn't reproduce myself) - Please reopen and include the vpn-port-ip-to-port model |
