السؤال #1
An engineering team must implement Unified MPLS to scale an MPLS network. Devices in the core layer use different IGPs, so the team decided to split the network into different areas. The team plans to keep the MPLS services as they are and introduce greater scalability. Which additional action must the engineers take to implement the Unified MPLS?
A. edistribute the IGP prefixes into another IGP to ensure end-to-end LSPs
B. ove the IGP prefixes into IS-IS as the loopback prefixes of the PE routers to distribute the prefixes to other to other routers to create end-to-end-to other routers to create end-to-end LSPs
C. onfigure the ABR routers as route reflectors that redistribute IGP into BGP
D. edistribute the IGP prefixes from one IGP into the other routers to ensure end-to-end LSPs
