Hi ,
We have an NSX DLR configured in a BGP peering relationship with 4 x NSX ESGs (2 x ESGs in one Datacenter and 2 x ESGs in another datacenter), with ECMP mode enabled on the DLR and each ESG. The 4 x NSX ESGs are in peering relationships with upstream physical routers local to them in the their respective datacenters.
We are advertising routes from the physical network to the ESGs, including the default route , and these routes are being advertised to the DLR from the ESGs.
Our challenge is that we are expecting to see 4 x instances of a route, one from each ESG, at the DLR however we only see 2 x routes when running sh ip route, and these are the routes from one datacenter only. We do not have any specific preferences set for BGP and filtering is minimal and configured the same on all ESGs, also the AS-Path is the same length on each route when viewed in the BGP outputs on the DLR (i.e. sh ip bgp)
