In your example above I´m missing the trailing dots behind images.example.com.
Imho it should read:
images.example.com. IN NS lc1
images.example.com. IN NS lc2
A delegation on your authoritative name server may look like this:
subdomain.f5test.local. IN NS lc_isp1.f5test.local.
subdomain.f5test.local. IN NS lc_isp2.f5test.local.
lc_isp1.f5test.local. IN A 10.1.0.253
lc_isp2.f5test.local. IN A 10.2.0.253
www.f5test.local. IN CNAME www.subdomain.f5test.local.
Both specified link controller interfaces are treated as authoritative for the subdomain.
The link controller will be able to resolve www.subdomain.f5test.local to A records associated with virtual servers on your link controller.
To accomplish this you will need 2 virtual servers (one per ISP link) which will be assigned to the so called Wide IP on the link controller.
The virtual servers are bound to a local pool of servers (subset of LTM feature).
