BGP peering from NSX-T edge to Cisco 9K switch

Hi All

Just wanted to get a second opinion. When peering from the NSX-T edge nodes to the ToR switches, I created VLAN 10 on leaf A and VLAN 20 on leaf B..Each VLAN has an SVI created and I use the SVI for the BGP peering. In the BGP config I just add update-source vlan 10/20 on the respective leafs.

Anything I need to watch out for with this config? Not sure if I should switch to using loopback and create ebgp multihop?
