Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 47

After reviewing the EVN configuration, a network administrator notices that a predefined EVN, which is known as "vnet global", was configured. What is the purpose of this EVN?

Answer options

• A. It aggregates and carries all dot1qtagged traffic.
• B. It refers to the global routing context and corresponds to the default RIB.
• C. It safeguards the virtual network that is preconfigured to avoid mismatched routing instances.
• D. It defines the routing scope for each particular EVN edge interface. B

Correct answer:

Explanation

The correct answer is B, as 'vnet global' serves as the global routing context which is associated with the default Routing Information Base (RIB). Option A is incorrect because the EVN does not specifically aggregate traffic types. Option C is misleading, as the purpose is not primarily about safeguarding against mismatched instances. Option D is also wrong, as it does not define the routing scope for specific interfaces.
