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?

WAHR

FALSCH

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.

The figure shows information about an LSP (Link-State PDU) generated by an IS-IS router.
From the LSP, you can infer that the router is not the DIS (Designated Intermediate System) of the local link.

Options:

WAHR

FALSCH

Comprehensive and Detailed In-Depth Explanation:
1. Understanding the DIS (Designated Intermediate System) in IS-IS
* In IS-IS, the DIS (Designated Intermediate System) is similar to the DR (Designated Router) in OSPF.
* Unlike OSPF, IS-IS does not use an election based on priority; instead, the router with the highest priority becomes the DIS.
* If there is a tie in priority, the router with the highest MAC address on the interface becomes the DIS.
* The DIS is responsible for generating additional LSPs (pseudonode LSPs) for the link and synchronizing the database between routers.
2. How to Identify If the Router Is the DIS from the LSP
* In the given LSP output, there are NO pseudonode LSPs (LSPs ending with .01).
* The DIS is responsible for creating pseudonode LSPs, which represent a multi-access network in the IS-IS topology.
* If the router were the DIS, it would generate both its own LSP (ending in .00) and a pseudonode LSP (ending in .01).
* Since we only see an LSP ending in .00, this confirms that the router is NOT the DIS.
3. Evaluating the Answer Choices
* Option A (TRUE) – Correct:
* Since no pseudonode LSP is present, the router is not the DIS.
* This confirms that the statement is TRUE.
* Option B (FALSE) – Incorrect:
* If the router were the DIS, it would generate pseudonode LSPs, but they are missing from the output.
* Therefore, the statement is NOT false.
Final Answer:

* IS-IS Designated Intermediate System (DIS) Selection Process
* Pseudonode LSP Generation in Multi-Access Networks
* IS-IS LSP Structure and Identification of DIS
