How do I check for ECMP with ebgp?

Hi all, 

I've enabled ip load sharing globally as well as maximum-paths in ebgp itself. 

Checking my route table, I see only one route to my destination. 

If I disable the ports, the secondary route does insert itself in the table. 

Is this expected behavior for ECMP over ebgp? 

I would think that the route table would show both hops for a destination with the same MED or weight, etc.

So, oddly enough.

 Removing

- maximum-paths ebgp 2 from router bgp

and enabling ip-load sharing 2

with maximum paths use-load-sharing works.

maybe a bug.
