local hostname resolution with Route Domains

Is there any possibility to create an entry in /etc/hosts/, which returns the IP-address in a proper Route Domain format? So either with %-notation or as F5 internal IPv6-address? I checked already Sol8439, but it's not working with both the %-format or the F5 IPv6-address.

 

By default it just returns the standard IPv4-address, but I have a requirement where the request with this resolved IP-address needs to be send out via a specific Route Domain. With the plain IPv4-address it goes out via the mgmt-Interface. Or is there any other possibility to tell the LB to use the correct Route Domain as outgoing interface?

 

Thank you!

 

Ciao Stefan :)

    Hi Nitass,

     

    I've already tried both, with an "official" DNS-server (which is reachable via mgmt-Interface) and even with local hostname resolution as described in Sol8439. In both cases I'm getting back a plain IPv4-address, but if the LB initiates a connection to it, it will NOT be send out via a specific Route Domain interface, but via the mgmt-Interface.

     

    Background: I need this for a HTTP-Auth configuration within APM, if I enter there the F5 IPv6-address it will be send out to the correct interface and connectivity is fine, but the request will be answered with a HTTP 400 Bad Request due to missing DNS-name in the host header. So if you can tell me how to modify the HTTP-Auth request, this would also be a solution for me ;)

     

    Thank you!
