Direct Connect Failover with two Virtual Interfaces (VIFs)


To test a Direct Connect (DX) failover using two VIFs on the same Direct Connect connection using the documentation AWS Direct Connect Failover Test. Does a resiliency model of at least two Direct Connect connections required for this type of failover testing?

The failover test simulates when one VIF is out of service, not if the entire DX is interrupted. A fiber cut or single device failure; as specified in the resiliency models, would require more than one physical connection.

for maximum resiliency, the documentation say:

separate connections that terminate on separate devices in more than one location

For high resiliency, the documentation say::

by using two single connections to multiple locations

Maximum resiliency requires two separate connections that terminate on two separate devices as shown in the docs.
