質問 # 105
On the IS-IS IPv6 network shown in the figure, after the network becomes stable:
* R1 can ping 2000:12::0, and
* The display ipv6 neighbors command can be used to display the MAC address corresponding to
2000:12::0.
Is this statement TRUE or FALSE?
- A. FALSE
- B. TRUE
正解：A
解説：
Comprehensive and Detailed In-Depth Explanation:
Understanding the IPv6 Addressing and IS-IS Network
* IPv6 Addressing in the Figure:
* R1 has the address: 2000:12::1/64
* R2 has the address: 2000:12::0/127
* The link between them is using a /127 subnet (2000:12::0/127).
* Behavior of IPv6 /127 Subnet Mask
* In IPv6, a /127 prefix is commonly used on point-to-point links to avoid the issue of subnet- router anycast (::0).
* RFC 6164 recommends using /127 instead of /64 for point-to-point links to reduce unnecessary anycast behavior.
* 2000:12::0 is the network address (first address in the subnet) and is not assigned to an interface.
Analyzing the Two Statements in the Question
Statement 1: "R1 can ping 2000:12::0" # (Incorrect)
* In IPv6, the first address (::0) in a /127 subnet is typically reserved as a network address and not assigned to any router.
* R1 cannot ping 2000:12::0 because it is not assigned to R2 as an active IP.
* Correct ping targets would be:
* R1 pinging R2's actual address (2000:12::1 or 2000:12::2 depending on numbering).
Statement 2: "display ipv6 neighbors command can be used to display the MAC address corresponding to 2000:12::0" # (Incorrect)
* The display ipv6 neighbors command is used to show the MAC address of an active neighbor (i.e., a reachable device).
* Since 2000:12::0 is not assigned to a specific router, it will not have a MAC address in the neighbor table.
Final Conclusion:
# R1 cannot ping 2000:12::0 because it is the network address in a /127 subnet.# The display ipv6 neighbors command cannot show a MAC address for 2000:12::0 because it is not assigned to a router.
Thus, the correct answer is: B. FALSE.
