JNCIS-SP: Juniper Networks Certified Specialist – Service Provider Routing — Question 59

What are Martian addresses on a Junos device?

Answer options

• A. IP addresses that are reserved for use only with MPLS VPNs.
• B. IP addresses that are never installed in the routing table.
• C. IP addresses that are reserved for use only with GRE tunnels.
• D. IP addresses specifically used for out-of-band management.

Correct answer: B

Explanation

Martian addresses are defined as IP addresses that are not valid within the context of the routing table and therefore are never installed. Options A, C, and D describe specific uses for IP addresses, but they do not accurately reflect the purpose of Martian addresses, which is to prevent routing issues by ignoring these addresses.
