Question 1 of 30
In a service provider environment, a network engineer is tasked with designing a Layer 3 VPN solution for multiple customers. Each customer has specific routing requirements and needs to ensure that their traffic is isolated from other customers while still being able to communicate with their own remote sites. The engineer decides to implement MPLS (Multiprotocol Label Switching) to facilitate this. Given the following customer requirements: Customer A requires a route target of 100:1, Customer B requires a route target of 200:1, and Customer C requires a route target of 300:1. If the engineer needs to configure the route distinguishers (RDs) for each customer, which of the following configurations would best ensure proper isolation and routing within the Layer 3 VPN?
RD for Customer A: 100:1, RD for Customer B: 200:1, RD for Customer C: 300:1
RD for Customer A: 1:100, RD for Customer B: 1:200, RD for Customer C: 1:300
RD for Customer A: 100:100, RD for Customer B: 200:200, RD for Customer C: 300:300
RD for Customer A: 10:1, RD for Customer B: 20:1, RD for Customer C: 30:1
