We have a N93180YX-EX with straight-through N2248-TP attached.
We have a 100Mb router that's connected to the FEX.
We want to run dynamic routing (BGP) between the attached router and N93180YX-EX.
In the cisco documentation we see the following :
When you connect a FEX to a Cisco Nexus 9000 series device, the queuing capability on the FEX host interface is limited. A router that is connected to a Layer 2 (using SVI interfaces) cannot participate in routing protocol adjacency. The FEX cannot be used as a peer because when congestion occurs on the FEX host interface, the control plane traffic is not prioritized. This limitation also applies to the FEX when it is connected to other Layer 3 devices, such as an ASA firewall, an ACE load balancer, or other Layer 3 networking devices that are running a dynamic routing protocol. Static routes to routers, ASA firewalls, ACE load balancers, and other Layer 3 network devices are supported
But i also read the following :Beginning with Cisco NX-OS Release 7.0(3)I4(2), Layer 3 is supported on FEX interfaces and subinterfaces on Cisco Nexus 9300 Series switches
Is it possible if we configure the FEX host interface as a layer 3 sub-interface that dynamic routing works over this interface?
Thanks for your help
