NEW QUESTION # 95
The router ID of R4 is 10.0.4.4. The LSA shown in the figure is displayed in the LSDB of R4.
Which of the following statements are true about the LSA?
Answer: A,C,D
Explanation:
Comprehensive and Detailed In-Depth Explanation:
Understanding the LSA Table in the Figure
The LSDB (Link-State Database) of R4 displays an Intra-Area-Prefix-LSA for Area 0.0.0.1. The table contains:
* Three LSAs originating from R4 (10.0.4.4)
* Prefixes referencing both Router-LSAs and Network-LSAs
* Different Sequence Numbers and Checksums, indicating multiple link-state changes OSPFv3 LSA Types Relevant to the Question
* Router-LSA (Type 1)
* Generated by every router to describe its links within an area.
* Network-LSA (Type 2)
* Generated only by the Designated Router (DR) for multi-access networks (such as Ethernet).
* Advertises all routers connected to the same segment.
* Intra-Area-Prefix-LSA (Type 9)
* Advertises IPv6 prefixes associated with a Router-LSA (Type 1) or Network-LSA (Type 2).
Analysis of Each Statement
A). The three LSAs belong to area 1. # (True)
* The table explicitly shows " Intra-Area-Prefix-LSA (Area 0.0.0.1) " , meaning all LSAs are for Area 1.
* The Link State IDs also indicate intra-area advertisements.
# Statement A is correct.
B). Area 1 is a stub area. # (False)
* There is no indication that Area 1 is a stub area.
* Stub areas do not receive Type 5 (External) LSAs, and the LSDB does not show Type 3 (Inter-Area) LSAs either.
* Network-LSAs (Type 2) are not typically seen in stub areas unless explicitly configured.
# Statement B is incorrect.
C). No OSPFv3 neighbor relationship is established on at least one link of R4. # (True)
* One LSA references a Router-LSA, while two reference Network-LSAs.
* A Router-LSA alone suggests that R4 has at least one point-to-point or unnumbered link with no OSPFv3 adjacency.
* This means R4 has an interface with no neighbor (e.g., a passive interface or down link).
# Statement C is correct.
D). R4 is the DR on a link. # (True)
* The presence of Network-LSAs (Type 2) indicates that a multi-access link exists.
* Since R4 is the origin of the Network-LSA, it must be the DR (Designated Router) for that link.
# Statement D is correct.
Final Conclusion:
# A. The three LSAs belong to area 1. (True)
# B. Area 1 is a stub area. (False)
# C. No OSPFv3 neighbor relationship is established on at least one link of R4. (True)
# D. R4 is the DR on a link. (True)
Thus, the correct answers are: A, C, D.

Answer: A
NEW QUESTION # 98
On an enterprise network shown in the figure, EBGP is deployed between CEs and PEs .
CE1 sends a VPN route to PE1.
Which of the following statements are false?
Options:
Answer: C,D
Explanation:
Comprehensive and Detailed In-Depth Explanation:
1. Understanding Site of Origin (SoO) in MPLS VPNs
* SoO (Site of Origin) is used in MPLS VPNs to prevent loops in multi-homed CE scenarios.
* Routes with the same SoO value are not advertised back to the same site.
2. Analysis of Each Answer Choice
A). " To enable CE3 to receive the route, run the command peer 10.1.1.1 soo 200:1 on PE1. " ( # False)
* SoO is used to prevent loops by tagging routes that belong to the same site.
* Applying SoO (200:1) on PE1 for CE1 means that any other PE (such as PE2) receiving the route will not advertise it back to the same site (CE1).
* This statement is false because applying SoO here does not directly enable CE3 to receive the route. Instead, CE3 must accept routes with SoO values properly configured.
B). " If the commands peer 10.1.1.1 soo 200:1 and peer 10.1.2.1 soo 200:1 are run on PE1, CE2 accepts the route. " ( # False)
* SoO ensures that a route received from one CE is not sent back to another CE in the same site.
* If SoO (200:1) is assigned to CE1 and CE2, routes will be blocked because they share the same SoO tag.
* Thus, CE2 will not accept the route, making this statement false.
C). " If the command peer 10.1.3.1 substitute-as is run on PE2, CE3 accepts the route. " ( # True)
* substitute-as allows a router to replace the received AS number in the AS_PATH with another AS number, ensuring that routes are accepted even when AS_PATH filtering is in place.
* This prevents CE3 from rejecting the route due to AS-Path loop prevention.
* # Thus, this statement is true.
D). " If no additional action is taken, CE3 discards the route. " ( # True)
* By default, CE3 will discard the route because of BGP loop prevention (same AS in the AS_PATH).
* To allow CE3 to receive the route, the allowas-in or substitute-as command must be configured on PE2.
* # Thus, this statement is true.
3. Evaluating the Answer Choices
Option
Correct?
Reasoning
A
# False
Applying SoO does not directly enable CE3 to receive the route.
B
# False
If both CE1 and CE2 have the same SoO value, CE2 will reject the route.
C
# True
Substitute-AS allows CE3 to accept the route by modifying the AS-Path.
D
# True
Without additional configuration, CE3 will discard the route due to AS-Path loop prevention.
# Correct answer: A and B are false.
Final Conclusion:
* SoO prevents routing loops in MPLS VPN multi-homing.
* CE2 will reject the route if it has the same SoO as CE1.
* CE3 requires the substitute-as or allowas-in command to accept the route.
* Thus, statements A and B are false.
