How to route packets from a route domain to default

My understanding on route domains is that one could configure a route domain to peek into a parent for routes, hence allowing packets to move across route domains.

 

 

However I've setup my device as follows:

 

 

- VLAN 1 (external)

 

- VLAN 110 (internal)

 

- Route domain 0 (default) with VLAN external

 

- Route domain 110 (internal) with VLAN internal, parent is route domain 0.

 

- Self IP 10.7.1.254 / 255.255.0.0 on VLAN external

 

- Self IP 192.168.0.254%110 on VLAN internal

 

- SNAT automap for all addresses on VLAN internal

 

 

In this configuration, I can't route packets from a host on VLAN internal out hosts on the external VLAN.

 

 

If I remove the route domains, then it works fine. That's with the following:

 

 

- VLAN 1 (external)

 

- VLAN 110 (internal)

 

- Route domain 0 (default) with all VLANs

 

- Self IP 10.7.1.254 / 255.255.0.0 on VLAN external

 

- Self IP 192.168.0.254 on VLAN internal

 

- SNAT automap for all addresses on VLAN internal

 

 

Any thoughts?
