direct routes are attached to the device. I.E. an SVI interface or an interface with an ip address on it.

hello,

from document it´s not clear what type of route are direct route. For me aggregate routes pointing to null 0 are static routes and not direct routes.

regards,

direct routes are attached to the device. I.E. an SVI interface or an interface with an ip address on it.

what is it exactly you are trying to accomplish?

I have two nexus Border Leaf conected via EBGP to 2 PEs. Every nexus has aggregate-routes for fabric IP configured in bgp and redistribute direct inside the BGP too. The problem is that in one Nexus I see not only agrregate route pointing to null but agrregate route from another Nexus that generate loop for traffic that dont have host route /32.

Is it the same aggregate? Can you post an example of the aggregate at site A in your scenario and the other route you are using from another Nexus and then also the /32 you are referring to and where that lives i.e. at site a or b or something?
