Question
Refer to the exhibit. ISP_A is a Tier-1 ISP that provides private Layer 2 and Layer 3 VPN services across the globe using an MPLS-enabled backbone network. Routers R1, R2, R13, and R14 are PE devices. ASRs R3 and R4 and ASBRs R11 and R12 are acting as route reflectors with preconfigured next-hop- self for all BGP neighbors. After the network experienced IGP RIB overflow with multiple routes, a network engineer is working on a more scalable network design to minimize the impact on local RIBs. The solution should be based on RFC 3107 and maintain existing QoS capabilities. Which task must the engineer perform to achieve the goal?
Options
- AImplement Seamless Segment Routing on the ABR routers.
- BImplement MPLS Traffic Engineering on PE routes only.
- CImplement Hierarchical MPLS VPLS across all LDP-enabled routers.
- DImplement Unified MPLS on all MPLS-enabled routers.
