Bug Description
this is with contrail 2.23 and 3.0
I would like to configure a subdomain to be delegated from a vDNS domain. Suppose we have a domain like "delegate.com" configured as a vDNS server. We want to add a subdomain like "sub.delegate.com" which is handled by a different name server.
This does not currently work. It appears that the NS record is being ignored.
We set up a vdns server with the following:
DNS Server vdns1
Display Name vdns1
UUID b37fe412-
Domain Name delegate.com
Time To Live 86400 (seconds)
Record Resolution Order Random
Floating IP Record dashed-
External Visibility Disabled
Reverse Resolution Disabled
Associated IPAMs admin:ipam-
Then we add a NS record like:
DNS Record Name sub.delegate.com
UUID a4775035-
DNS Record Type NS (Delegation Record)
DNS Record Data google.com
Time To Live 86400 (seconds)
DNS Record Class IN
Introspection shows:

however i see the following behavior:
this works:
root@gngsvm001d
Server: 10.204.216.24
Address: 10.204.216.24#53
Non-authoritative answer:
www.delegate.com canonical name = delegate.
delegate.
Name: www-delegate-
Address: 52.19.148.186
Name: www-delegate-
Address: 54.77.167.247
But the subdomain www.sub.
root@gngsvm001d
Server: 10.204.216.24
Address: 10.204.216.24#53
** server can't find www.sub.
