F5 GTM Subdelegation
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:
$TTL 604800
@ 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?
Thank you in advance
