CirrusProblem when attempting to route between two route domains.
Hello,
I have this scenario
- A front-end vlan (vlan_one), belonging to Route Domain #1
- A back-end vlan (vlan_two), belonging to Route Domain #2
- Some virtual servers in between, to balance traffic from the front-end users to the back-end servers.
Now, some administrators behind a firewall connected to the front-end (vlan_one) need to reach the back-end servers directly. So that routing between Routing Domains #1 & #2 should be enabled.
How can I perform the routing between both Route Domains?
I disabled the "strict isolation" on both Route Domains, plus within the Route Domain #1 (Front-End) I set the Route Domain #2 (Back-End) as his parent Domain.
But the routing does not seems to work.
Do you think this is the right way to do that? Or did I left something?
Regards in advance.

Albert_CollThank you both for your inputs. By using tcpdump and other features at the perimeral firewall, we realized that the problem was not caused at the BIG-IP LTM itself, but in the firewall configuration.
Best regards.

Hello Albert.
Take into account this:
"When you create a route domain, you can associate a parent route domain. When the BIG-IP system is unable to find a necessary route in the child domain, the system can then search an associated parent route domain for a possible route."
I suspect that you have one route configured in your child domain to reach your destination. You can check with:
ip routeAnyway, your best chance is to route traffic between route domains using an external router.
Regards,
Dario.
