Comment 11 for bug 2051935

Hello:

So if I'm not wrong, the goal is to cascade two routers and from the down one to be able to reach the upper router external GW. Please provide a reproducer with the steps to create the networks, subnets, routers, attach the subnets to the routers, add the external GW to the router and add the router/subnet routes provided.

What is the external network type you are using?

BTW, we have a test that check the communication between two nested routers and the VMs on the opposite networks [1]. It's worth mentioning that none of these networks are external GW networks in any of these routers; please check how the router routes are added.

Regards.
