Thu, 19 Oct 2017 21:28:04 +0000

3-odl cluster
availability zone- single host

Procedure:
1. create 2 networks- net1-11.11.11.0/24 and net2-22.22.22.0/24 with gw on each- 11.11.11.254 and 22.22.22.254 resp.
2. create 2 VM's on net1
3. attach new interface to vm2, from net2- gets 22.22.22.2
4. add router interfaces and ping new IP (after adding it in the vm)
5. edit def gw on net1 to 11.11.11.250-

delete router interface,
recreate it with the new IP
edit subnet with the new gw
in both vm's edit the def gw
6. ping 22.22.22.2 from vm1- works for a while then stops and restarts.
7. check with ping to router ip, from both vm's- works for a while (~150 pings), then stops for about 150 pings, then starts again on its own.
