[j-nsp] internal traffic forwarding between instances

[Stefan Fouant]

What happens if you leak interface routes between instance1 and inet.0?

Hi!

 

I try to accomplish the following:

 

I have two J-Series routers in chassis cluster mode. I have two reth-interfaces, reth1 and reth2. The interfaces are connected to a switch, so I have four cables to one VLAN. I have one routing-instace instance1, which is configured, together with inet.0 running OSPF.

 

Behind the switch is a firewall, which is also running OSPF. I have configured rib-groups, so I have copied the routing tables from inet.0 to instance1.inet.0 and instance1.inet.0 to inet.0. I see all of the routes learned from OSPF. I have also copied a static default route into instance1.

 

Now I am killing all connections but one, which is configured to the instance1. In the routing table I see, that all the routes are destined to reth2, which is in instance1. But there seems to be no traffic forwarding. Am I lacking something? Do I have to configure something else to enable that? I use instance-type virtual-router. The forwarding has to be made internal without a physical interface. Is that possible?

 

Regards,

 

Matthias
