---------------------------------------
Summary: DhcpEntryCommand fails on Router VM on CS4.0 and vSphere5
with Advanced Network Zone
Key: CLOUDSTACK-599
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-599
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Network Controller
Affects Versions: 4.0.0
Environment: CS4.0 and vSphere5 with Advanced Network Zone
Reporter: ilya musayev
Fix For: 4.0.1, 4.1.0
Identified and resolved issue for Router VM on vSphere 5.0 and CS 4.0 - where a
router VM would come up however the Link Local IP would be unreachable until
you initiate a ping request from Router VM itself. As the result - you are
unable to deploy instances. The logs display a problem with DhcpEntryCommand as
Router VM is unreachable. The router VM does not receive inbound communication,
but outbound communication is fine.
The ping updates the ARP table with additional MAC entry of the gateway. We are
ping the gateway of CS host specifically - as this is the major needed source
of communication. Once ARP table is updated - communication works in both
directions.
