Description
This article describes the expected behavior for CNAME target reference.
Solution
Available option
CNAME Record
Alias - An alias name to another true or canonical domain name (the target). For instance, www.example.com is an alias for example.com.
Target – The true or canonical domain name. For instance, example.com.
Explanation
Primary domain may reference to an external third party domain (cloud services) for application redirection.
Configuration
# config global-dns-server zone
# edit "www"
# set domain-name example.com.
# config cname-record
# edit 1
# set alias app.example.com
# set target cloud.fortinet.com.
# next
# end
Validation
Verify DNS query with the below tools:
Note that the primary domain will append to the configured target domain if trailing dots are not configured
For example: cloud.fortinet.com. example.com
If the target domain expected to be the FQDN, then the trailing dots should be added.
# config cname-record
# edit 1
# set alias app.example.com
# set target cloud.fortinet.com[.] ---> trailing dot (without the square bracket)
# next
