A service provider is expanding its MPLS network to include access and aggregation domains. The current core uses LDP for label distribution. The provider wants to extend MPLS to the access layer without running a full IGP in the access domain. Which architecture should be used to achieve this?

Single IGP domain with LDP across all routers

Unified MPLS (seamless MPLS) with inter-domain label distribution

Segment Routing with SRGB only in the core

In a Unified MPLS architecture, how are the access, aggregation, and core domains typically interconnected?

Using static MPLS labels configured on every router

Using LDP only within the core domain

Using BGP as the label distribution protocol between domains

Using a single IGP instance across all domains
