Known Behavior
The following are known behaviors in this release of Contrail.
- DNS record updates from a controller DNS server to a named server might be missing even after repeated retries. this is because there is no infrastructure currently to sync records across named servers.
- DNS queries from an agent are now sent to both named servers
that were learnt using discovery. There is a very low probability
of records missing on both named servers.
The first good response from either of the named servers is used to update the DNS client that sent the DNS query request. If there is no good response, the last bad response is sent to the DNS client to inform the client of the error.
Use the following to display a list of named servers to which queries are sent:
