A public VIF establishes BGP reachability for supported AWS public endpoints over the dedicated connection without turning them into private IP resources; this belongs to AWS public service routing over Direct Connect, while the problem is encrypted hybrid traffic on dedicated transport.

IPsec tunnels can establish encrypted AWS connectivity without waiting for Direct Connect cross-connect provisioning; this changes fast establishment of encrypted hybrid connectivity, not the necessary encrypted hybrid traffic on dedicated transport.

In the heterogeneous backup path for circuit outages workflow, an independent IPsec tunnel over the Internet provides a separate transport failure domain when the dedicated circuit becomes unavailable; the current case needs encrypted hybrid traffic on dedicated transport.

Geographic and facility diversity protects against a single colocation or circuit fault that redundant VLANs on one port cannot survive; that addresses physical redundancy across interconnect facilities, rather than heterogeneous backup path for circuit outages.

Direct Connect provides dedicated transport, while the layered VPN supplies IPsec encryption absent from ordinary VIF forwarding; this belongs to encrypted hybrid traffic on dedicated transport, while the problem is heterogeneous backup path for circuit outages.

IPsec tunnels can establish encrypted AWS connectivity without waiting for Direct Connect cross-connect provisioning; this changes fast establishment of encrypted hybrid connectivity, not the necessary heterogeneous backup path for circuit outages.

A LAG bundles supported physical ports into one logical interface, while all member links remain inside the same location failure domain; that addresses aggregated physical ports at one Direct Connect location, rather than scalable IP address planning without overlapping prefixes.

Transit VIFs connect on-premises routers to transit gateways through Direct Connect gateways, reducing per-VPC VIF sprawl; this changes Direct Connect transit access to many routed VPCs, not the necessary scalable IP address planning without overlapping prefixes.

In the heterogeneous backup path for circuit outages workflow, an independent IPsec tunnel over the Internet provides a separate transport failure domain when the dedicated circuit becomes unavailable; the current case needs scalable IP address planning without overlapping prefixes.

Private IP VPN can run IPsec tunnels on a Direct Connect path using private endpoint addresses and centralized transit routing; that addresses private-addressed IPsec encryption on dedicated hybrid links, rather than dynamic GRE overlay integration with transit routing.

Dynamic Site-to-Site VPN connectivity uses BGP to exchange reachable prefixes and respond to routing changes; this belongs to exchange of dynamic routes over IPsec tunnels, while the problem is dynamic GRE overlay integration with transit routing.

A LAG bundles supported physical ports into one logical interface, while all member links remain inside the same location failure domain; that addresses aggregated physical ports at one Direct Connect location, rather than control of AWS egress preference across hybrid links.

AWS Direct Connect terminates at its location; carrier/MPLS reach from enterprise sites must be provisioned separately; this belongs to private WAN access to a Direct Connect entry point, while the problem is control of AWS egress preference across hybrid links.

The enterprise's own local preference policy selects an outbound path to AWS without requiring changes to AWS advertisement behavior; this changes control of customer-originated traffic using internal BGP policy, not the necessary control of AWS egress preference across hybrid links.

In the Direct Connect transit access to many routed VPCs workflow, transit VIFs connect on-premises routers to transit gateways through Direct Connect gateways, reducing per-VPC VIF sprawl; the current case needs control of AWS egress preference across hybrid links.

EBGP session configuration must match the advertised peer ASN and local routing policy; accidental ASN mismatches prevent session establishment; that addresses compatible autonomous-system identities for BGP peers, rather than control of customer-originated traffic using internal BGP policy.

AWS honors supported communities to influence its outbound routing decision toward advertised customer prefixes; this belongs to control of AWS egress preference across hybrid links, while the problem is control of customer-originated traffic using internal BGP policy.

An independent IPsec tunnel over the Internet provides a separate transport failure domain when the dedicated circuit becomes unavailable; this belongs to heterogeneous backup path for circuit outages, while the problem is aggregated physical ports at one Direct Connect location.

The LOA-CFA identifies the approved circuit termination and facility details needed for the physical cross-connect; this changes physical cross-connect authorization at the interconnect facility, not the necessary aggregated physical ports at one Direct Connect location.

Direct Connect provides dedicated transport, while the layered VPN supplies IPsec encryption absent from ordinary VIF forwarding; that addresses encrypted hybrid traffic on dedicated transport, rather than scalable hybrid throughput rather than repeated encapsulation.

An independent IPsec tunnel over the Internet provides a separate transport failure domain when the dedicated circuit becomes unavailable; this belongs to heterogeneous backup path for circuit outages, while the problem is scalable hybrid throughput rather than repeated encapsulation.

IPsec tunnels can establish encrypted AWS connectivity without waiting for Direct Connect cross-connect provisioning; this changes fast establishment of encrypted hybrid connectivity, not the necessary scalable hybrid throughput rather than repeated encapsulation.

This produces physical cross-connect authorization at the interconnect facility: The LOA-CFA identifies the approved circuit termination and facility details needed for the physical cross-connect; the stem instead tests scalable hybrid throughput rather than repeated encapsulation.

For resilience against one IPsec tunnel failure, each Site-to-Site VPN connection provides two tunnels, enabling a surviving tunnel to carry traffic if its peer path fails; however, the present requirement is scalable hybrid throughput rather than repeated encapsulation.

Overlapping networks do not supply unique destination identities, so ordinary route propagation cannot establish unambiguous bidirectional reachability; this belongs to unique routing identities for hybrid overlapping networks, while the problem is bidirectional path symmetry through stateful appliances.

In the inter-Regional transit routing without BGP propagation workflow, transit gateway peering does not dynamically propagate attached VPC or VPN prefixes, so destination routes must be programmed explicitly; the current case needs unique routing identities for hybrid overlapping networks.
