[NETVIRT-599] L3 VMs sometimes unreachable because TunnelStateChangeListener can't read DPNTEPsInfo

Fri, 6 Apr 2018 00:07:15 +0000

The flow :

Setup: ODL + CONTROL node + 2 compute nodes
Creating ext-net and private networks
Creating a router
Connecting the router to networks
Launch 2 vm’s

The result: sporadic failure while installing T21 rules for one of VM’s .

It seems to be side-effect of the review [1] where storing ITM models to DS is replaced to batching utilities instead of individual transaction submit
Please review and decide if it’s possible to remove using BatchingUtils for updating DPNTEPsInfo, like it is done for InternalTunnels list [2]
