Does not support IPv6
Routes from the network Load Balancer
How does Private Link work with on-site network
Direct Connect
(only supports 802.1Q)
Proxy Protocol V2
Network Load Balancers use Proxy Protocol v2 to send additional connection information such as the source and destination. (gain insights)
DNS
When an interface endpoint is created, endpoint-specific DNS hostnames are generated that can be used to communicate with the service.
LAG
linked aggregation group used in direct connect with more than one connection.
What speeds does direct connect support?
port speed of 1 Gbps, 10 Gbps, or 100 Gbps.
Direct Connect interfaces
Private Virtual Interface-any vpc in same space
Public Virtual Interface-publicly in same region
Transit Virtual Interface-regional public and private using Transit gateway

does not support Path MTU Discovery
Maximum packets per second (PPS) per VPN tunnel is 140,000.
