NEW QUESTION # 296
IS-IS is a link-state routing protocol that uses the SPF algorithm for route calculations. As shown in the figure, at the same time, a certain area has IPV4 and IPV6 and runs IS-IS to achieve network interconnection, of which R2 only supports IPV4 Regarding the topology calculation of the network, which of the following statements is correct?
Answer: C
NEW QUESTION # 297
OSPF is deployed on a campus network to implement network interconnection. An engineer configures R2 as shown in the figure. Which of the following statements is incorrect about LSAs on the OSPF network?
Answer: B
Explanation:
# Analyze the Configuration:
[R2] acl 2000
[R2-acl-basic-2000] rule deny
[R2] ospf
[R2-ospf-1] area 1
[R2-ospf-1-area-0.0.0.1] filter 2000 import
[R2-ospf-1-area-0.0.0.1] quit
[R2-ospf-1] default-route-advertise always
# Understanding Key Concepts:
Type 3 LSAs (Inter-Area Routes):
Generated by ABRs to advertisesummary routesbetween areas.
Filtering Type 3 LSAsis possible using import filters (like in Area 1).
Type 5 LSAs (External Routes):
Flooded only within the same ASbutdo not enter stub or NSSA areas.
#Breakdown of the Options:
A). Type 5 LSAs are flooded in Area 1##Incorrect
If Area 1 is astub or NSSA, thenType 5 LSAs are not allowed.
Although the diagram does not explicitly say Area 1 is a stub/NSSA,real deployments often use stub areas at the edge (like Area 1).
More importantly,the filter is applied to Area 1, and there isno redistributionof external routes into Area 1 in the config.
Therefore, Type 5 LSAs wouldnot be floodedthere.
B). Type 3 LSAs are not flooded in Area 1##Correct
The command filter 2000 import with ACL rule deny meansType 3 LSAs are filtered from Area 0 into Area 1.
C). Type 3 LSAs are not flooded in Area 2##Correct
There isno filter applied to Area 2, so thiscould be false,butsince the question asks for the incorrect statement, this is not the answer.
D). Type 5 LSAs are flooded in Area 2##Correct
Area 2 is not shown to be stub or NSSA, and there's no filter or restriction configured.
Hence,Type 5 LSAs are allowedandflooded in Area 2.
#Correct answer: A. Type 5 LSAs are flooded in Area 1.

NEW QUESTION # 298
What can be determined from the following figure?
Answer: A
Explanation:
To determine R3's role (Level-1, Level-2, or Level-1-2) based on the provided output of the display ipv6 routing-table protocol isis command on R3, we need to analyze the IS-IS routing information and understand IS-IS hierarchy and behavior, particularly in the context of IPv6 routing. Let's break it down step by step:
Understanding the IS-IS Levels and Hierarchy:
IS-IS (Intermediate System to Intermediate System) is a link-state routing protocol that supports a two-level hierarchy:
Level-1: Routers within the same area, responsible for intra-area routing. Level-1 routers only maintain routing information for their area and rely on Level-1-2 routers to reach other areas.
Level-2: Routers that form the backbone, connecting different areas for inter-area routing. Level-2 routers maintain routing information across areas.
Level-1-2: Routers that operate both at Level-1 (within their area) and Level-2 (to connect to other areas). These routers act as boundary routers between Level-1 areas and the Level-2 backbone.
A router's role (Level-1, Level-2, or Level-1-2) determines which types of adjacencies it can form and what routing information it advertises or receives.
Analyzing the Output:
The output shows R3's IPv6 routing table with routes learned via IS-IS, specifically:
Destination: 2082:EDFC:DDCC::B824:0/127, Protocol: ISIS-L1
This route is learned via IS-IS Level-1 (ISIS-L1), indicating that R3 has a Level-1 adjacency and is receiving or advertising routes within its area.
The next hop (FE80::2E0:FCFF:FE45:6A3E) and interface (GigabitEthernet0/0/0) suggest this route is intra-area.
Destination: 2082:EDFC:DDCC::B891:0/127, Protocol: ISIS-L2
This route is learned via IS-IS Level-2 (ISIS-L2), indicating that R3 has a Level-2 adjacency and is receiving or advertising routes for inter-area or backbone routing.
The next hop (FE80::2E0:FCFF:FE50:406F) and interface (GigabitEthernet0/0/1) suggest this route is for a different area or the backbone.
Both Level-1 and Level-2 routes are present in R3's routing table, which provides critical insight into R3's role.
Determining R3's Role:
Level-1 Routers:
Level-1 routers only participate in Level-1 adjacencies and maintain routing information for their area. They do not have Level-2 routes or adjacencies unless connected to a Level-1-2 router. Since R3 has a Level-2 route (ISIS-L2), it cannot be exclusively a Level-1 router.
Level-2 Routers:
Level-2 routers focus on inter-area routing and typically do not maintain Level-1 routes unless they are also configured as Level-1-2. Since R3 has a Level-1 route (ISIS-L1), it cannot be exclusively a Level-2 router.
Level-1-2 Routers:
Level-1-2 routers operate both at Level-1 (for intra-area routing) and Level-2 (for inter-area routing). They can form adjacencies with both Level-1 and Level-2 neighbors and maintain both types of routes. The presence of both ISIS-L1 and ISIS-L2 routes in R3's routing table indicates that R3 is participating in both Level-1 and Level-2 adjacencies, making it a Level-1-2 router.
Evaluating Each Option:
A . R3 must be a Level-2 device.
This is incorrect because R3 has ISIS-L1 routes, indicating it is also participating in Level-1 adjacencies, which Level-2-only devices do not do. Level-2 devices focus solely on inter-area routing and do not maintain Level-1 routes.
B . The device role of R3 cannot be determined.
This is incorrect because the presence of both ISIS-L1 and ISIS-L2 routes in the routing table clearly indicates R3's role. The combination of Level-1 and Level-2 routes confirms R3 is a Level-1-2 router.
C . R3 must be a Level-1-2 device.
This is correct. The routing table shows both ISIS-L1 (Level-1) and ISIS-L2 (Level-2) routes, meaning R3 is operating as both a Level-1 and Level-2 router, which defines a Level-1-2 device.
D . R3 must be a Level-1 device.
This is incorrect because R3 has ISIS-L2 routes, indicating it is also participating in Level-2 adjacencies, which Level-1-only devices do not do. Level-1 devices only maintain intra-area routes and rely on Level-1-2 routers for inter-area reachability.
Additional Considerations:
The Flags: D in the output typically indicates a directly connected route or a route downloaded to the forwarding table, but it does not affect the determination of R3's IS-IS level.
The preference (15) and cost (20) are standard for IS-IS routes and do not impact the level determination.
In Huawei's IS-IS implementation, routers can be configured explicitly as Level-1, Level-2, or Level-1-2 using commands like isis level-1-2 under the IS-IS process. The presence of both Level-1 and Level-2 routes confirms R3's configuration as Level-1-2.
Huawei HCIE-Datacom Context:
According to Huawei HCIE-Datacom documentation, IS-IS routers can operate at different levels, and the routing table's protocol type (ISIS-L1 or ISIS-L2) indicates the level of adjacency. A router with both Level-1 and Level-2 routes is necessarily a Level-1-2 device, as it participates in both intra-area and inter-area routing.
The display ipv6 routing-table protocol isis command on Huawei devices shows routes learned via IS-IS, and the protocol type (L1 or L2) directly reflects the router's role in the IS-IS hierarchy.
Conclusion:
Based on the presence of both ISIS-L1 and ISIS-L2 routes in R3's IPv6 routing table, R3 must be a Level-1-2 device, as it is participating in both Level-1 (intra-area) and Level-2 (inter-area) adjacencies. Therefore, the correct answer is C.

NEW QUESTION # 299
In the following figure, OSPF is enabled on all router interfaces. The IP addresses marked in the figure belong to Loopback0 of the routers.
The Loopback0 addresses of R1 and R2 are advertised in Area 1, the Loopback0 address of R4 is advertised in Area 0, and the Loopback0 addresses of R3 and R5 are advertised in Area 2. Given this, which of the following IP addresses can ping each other?
Answer: D
Explanation:
Understanding OSPF Multi-Area Routing
# OSPF (Open Shortest Path First) is a link-state routing protocol that uses a hierarchical area design for scalability.# OSPF Areas in the Diagram:
* Area 0 (Backbone Area): Contains R4 (Loopback 10.0.4.4/32).
* Area 1: Contains R1 (Loopback 10.0.1.1/32) and R2 (Loopback 10.0.2.2/32).
* Area 2: Contains R3 (Loopback 10.0.3.3/32) and R5 (Loopback 10.0.5.5/32).
* R1 and R2 connect Area 1 to Area 0.
* R1 and R3 connect Area 1 to Area 2.
How OSPF Advertises Routes Across Areas
# Intra-area communication (within the same area) is always possible.# Inter-area communication is possible if the ABR (Area Border Router) correctly advertises routes.# OSPF does NOT automatically advertise routes from one non-backbone area (e.g., Area 2) to another (e.g., Area 0) unless explicitly allowed.
Analysis of the Answer Choices:
# A. 10.0.3.3 and 10.0.5.5 (Incorrect)
* Both R3 (10.0.3.3) and R5 (10.0.5.5) are in Area 2.
* R3 and R5 can communicate directly, but OSPF rules require an Area Border Router (ABR) to share routing information between areas.
* Since no information is provided about inter-area route redistribution, we cannot confirm that R3 and R5 can reach each other.
# B. 10.0.2.2 and 10.0.5.5 (Incorrect)
* R2 (10.0.2.2) is in Area 1, and R5 (10.0.5.5) is in Area 2.
* R2 does NOT have direct OSPF reachability into Area 2.
# C. 10.0.2.2 and 10.0.3.3 (Correct)
* R2 (10.0.2.2) is in Area 1, and R3 (10.0.3.3) is in Area 2.
* R1 connects both Area 1 and Area 2, meaning R2 and R3 can communicate via R1.
* R1 is the ABR (Area Border Router) between Area 1 and Area 2, so it will advertise routes from R3 to R2 and vice versa.
# D. 10.0.4.4 and 10.0.2.2 (Incorrect)
* R4 (10.0.4.4) is in Area 0 (Backbone), and R2 (10.0.2.2) is in Area 1.
* R2 does NOT connect directly to Area 0, so R2 does not learn routes from Area 0 unless R1 explicitly redistributes them.
* No explicit information about route redistribution is provided.
# Reference: Huawei HCIE-Datacom Guide - OSPF Multi-Area Routing & ABR Role Real-World Application:
* Enterprise WAN Networks: Multi-area OSPF is used to scale large enterprise networks while maintaining fast convergence.
* Service Provider Networks: ABRs control route distribution, preventing unnecessary flooding of routing updates across areas.
