Service provider XYZ plans to provide dedicated Internet access and MPLS L3VPN services to business
customers. XYZ has these design specifications:
– MP-BGP running on the core MPLS P routers with external Internet routes.
– The core network will include 16 Point of Presence IP POPs throughout the Asia-Pacific region.
– An additional nine non-P routers will use EBGP peering with multiple providers for Internet traffic.
– An additional 50 PE routers will provide end customers with dedicated Internet access and L3VPN services
throughout the Asia-Pacific region.
In what two ways can the MP-BGP be removed from the MPLS P core routers and still provide dedicated
Internet access and MPLS L3VPN services? (Choose two.)
A. Disable BGP from the MPLS core P routers and have the MPLS core P routers run OSPF and LDP.
B. Enable separate BGP control plane routers using a route reflector server concept that will be fully meshed
with peer route reflector servers and have clients as MPLS PE routers and EBGP peering routers.
C. Enable all EBGP routers as route reflector servers and MPLS PE routers as their clients.
D. It is not possible to disable BGP from the MPLS core P routers without impacting the dedicated Internet
access and MPLS L3VPN services.
