An engineer working for a service provider with an employee ID: 4859:86:437 must design a solution to provide remote connectivity over the public internet. The design must: - securely connect…

MPLS provided service with BGP is typically an ISP-provided service, not a solution for a company to build its own remote connectivity over the public internet.

A full mesh ISIS with GRE tunnels and IPsec would involve N-squared tunnels, resulting in extensive and complex configuration at remote sites, violating the minimal configuration requirement.

Dual DMVPN (Dynamic Multipoint VPN) provides secure, on-demand IPsec tunnels from spokes to multiple hubs, ensuring redundant paths and significantly minimizing configuration at remote sites. EIGRP routing over DMVPN supports unequal cost load balancing (variance), which enables intelligent auto path selection based on connection quality or failure, and it fully supports IP multicast traffic, meeting all specified requirements for resilience and functionality.

A full mesh OSPF with IPsec tunnels would also suffer from high configuration complexity for many remote sites, and OSPF's Equal Cost MultiPath (ECMP) is less flexible for auto path selection based on varying connection quality compared to EIGRP's variance.
