I am practicing sub delgeation exercise in the lab, in my DNS server I am delegating subdomain wip.domain.com to the F5 devices, current zone file for domain.com:
@ IN SOA domain.com. admin.domain.com. (
57 ; Serial
900 ; Refresh 15 mins
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
; name servers - NS records
IN NS ns1.domain.com.
IN NS ns2.domain.com.
; name servers - A records
ns1.domain.com. IN A 192.168.242.200
ns2.domain.com. IN A 192.168.242.201
www.domain.com. IN CNAME www.wip.domain.com.
wip.domain.com. IN NS gtm1.wip.domain.com.
wip.domain.com. IN NS gtm2.wip.domain.com.
gtm1.wip.domain.com. IN A 10.10.4.50
gtm2.wip.domain.com. IN A 172.16.14.50
In the F5 GTM device I created a wideip - www.wip.domain.com - this works returning the relevant A record.
Now I noticed when I created this, a zone was created in zonerunner "this.name.is.invalid" which creates a default NS/SOA and A record (pointing to 127.0.0.1).
What is the correct process that must be done further? since any NS queries etc which are polled to the GTM respond with "this.name.is.invalid"
- should I update zonerunner with the subdomain zone records, I tried to do this from https://support.f5.co/csp/article/K35603050 but adding a second nameserver in the zone failed (gtm2.wip.domain.com). - or should I create a primary/secondary nameserver on the GTM's for the subdomain?
The existing SOA and NS records of the zone under the zonerunner will not be overwritten by the above operations. I recommend you to delete the wideip www.wip.domain.com and then delete zone wip.domain.com under zonerunner Finally, modify the SOA and NS record values of the zone automatically generated by wideip: modify gtm global-settings general wideip-zone-nameserver gtm2.wip.domain.com. After the above steps are completed, you can create a wideip www.wip.domain.com, and then observe the SOA and NS records whether change to gtm2.wip.domain.com.
and create a another wideip www.test.com, and under the ZoneRunner zone test.com.
its NS and SOA will also be gtm2.wip.domain.com.
Tips： low version in GTM, such as V12, wideip create zone default SOA and NS value is F5 hostname
