NimbostratusRouting between vlans in different domains
Hi,
I have vlanX configured on the ltm in route domain 0 with the servers pointing default gateway to the self ip on vlanX. There is another vlan vlanz configured on route domain 1 and has a self ip. Both route domains are configured with strict isolation and no parent domains.
I understand that if I remove the strict isolation on both route domains, I can specify routes using gateways across different route domains but how can I enable communication between these route domains where both vlans are terminated on LTM.
I am not able to add a route on route domain 0 specifying traffic exit vlanY which is in a different route domain.
How can I enable traffic between two vlans configured on ltm in two different route domains with strict isolation disabled. How can I specify the route? Or what else I need to do.
Ltm version 11.5.0
Thanks, Dowlas.

Dowlas_LoboIf i try to add a route using Resource as VLAN/Tunnel in domain 0 which has vlanX to point traffic to vlanY in domain 1, it gives the following error. 01070712:3: Cannot get device index for vlanY in rd0 - ioctl failed: No such device- JRahm

if you have disabled strict isolation on both route domains, traffic should flow between them. You don't need to add routes for them to talk to each other, the routing table should work as is assuming all routes necessary for traffic to hit destinations in domain 2 and domain 1 exist. That said, remember that a route is honored only when there is a virtual server configured to forward such traffic.

I created a virtual server in route domain 0 and assigned a default pool which has servers in route domain 1 but it does not work.
- Dowlas_LoboI also tried it the other way round by creating a virtual server in route domain 1 and adding a default pool which has servers in route domain 0, enabled strict isolation and configured route domain 0 as the parent domain inside route domain 1. In this case it work but what happens if I add a default route in route domain 1 pointing to another ip in vlanY ? Will it use the default route or use the connected route from route domain 0
