F5 DNS Forwarding
Hi Guys,
We have configured F5 DNS as GSLB and not running it as a BIND.
We have got some external bind servers configured as standalone servers.
Now I want to set up dns forwarding on F5 based on the domain.For example
If the request is coming for anything on the domain *.abc.com and if F5 doesn't know about it then it will forward that request to external bind server.In a nutshell
- dns request comes to F5 for *.abc.com, if it finds the match then reply with the answer
- dns request comes to F5 for *.abc.com, if it doesn't find the match it will forward the request to bind server 10.10.10.10
- dns request comes to F5 fo5 *.xyz.com, if it finds the match then reply with the answer
- dns request comes to F5 for *.xyz.com, if it doesn't find the match it will forward the request to bind server 10.10.10.10
And finally for all domains i.e everything else(/) F5 will forward the dns request to different bind server 20.20.20.20
Please if anyone could help me with iRULES or with any other approach then it will be appreciated.
Thanks, Pan
