NEW QUESTION # 32
Network administrator A wants to use ACL to match specific routing entries. Which of the following routing entries will be matched by the ACL rules in the figure? (Multiple choice) acl number 2000 rule 10 permit source 10.0.0.0 0.0.6.0
Answer: A,B
NEW QUESTION # 33
On the OSPF network shown in the figure, area 1 is an NSSA, area 2 is a common area, and R4 imports an external route 10.0.4.4/32. The router ID of each router is 10.0.X.X, where X is the number of the router. The command asbr-summary 10.0.4.0 255.255.255.0 is configured in the OSPF processes of R1 and R3. Which of the following statements is true?
Answer: D
Explanation:
# Topology Key Points:
* Area 1 is an NSSA (Not-So-Stubby Area).
* R4 is injecting an external route: 10.0.4.4/32.
* The command asbr-summary 10.0.4.0 255.255.255.0 is applied on R1 and R3, which are ABRs connected to the NSSA.
# Behavior of asbr-summary in Huawei OSPF:
* The asbr-summary command summarizes external routes from an ASBR into an area.
* It causes the ABR to generate a summary LSA (Type-3) for the summary prefix instead of the more specific original routes.
* As a result, routers in other areas receive only the summary (e.g., 10.0.4.0/24), not the original more- specific route (10.0.4.4/32).
# What Happens in Each Router:
* # R4 originates route 10.0.4.4/32 as an NSSA Type-7 LSA.
* # R1, as an ABR, translates the Type-7 LSA to Type-5 and applies the asbr-summary, advertising
10.0.4.0/24 into Area 0.
* # R3, another ABR, learns the summarized route and advertises 10.0.4.0/24 into Area 2.
* # R3 will NOT contain 10.0.4.4/32, only the summarized 10.0.4.0/24.
# Final Answer: C. The routing table of R3 contains the route 10.0.4.0/24.
Official Huawei Extract:
" When a summary route is configured using the asbr-summary command, the ABR or ASBR advertises the summary route into other areas instead of advertising specific routes. This helps reduce the size of the LSDB and routing table in large-scale networks. "

NEW QUESTION # 34
On the network shown in the figure, IS-IS IPv6 runs on R2, R6, and R3, and the IPv6 address of Loopback0 on R6 is 2000::6/128 . OSPFv3 runs on other links. Area 1 is a stub area, and Area 2 is an NSSA . IS-IS routes are imported to OSPFv3 on R2 and R3. Which of the following statements are true?
Answer: B,C,D
Explanation:
Comprehensive and Detailed In-Depth Explanation:
To analyze the correct answer, we need to break down the topology and protocol behaviors step by step:
* Understanding the IS-IS and OSPFv3 Network Setup:
* IS-IS IPv6 is running between R2, R6, and R3 .
* OSPFv3 is running on other links.
* Area 1 is a stub area , which means it does not accept external routes but can have a default route (::/0).
* Area 2 is an NSSA (Not-So-Stubby Area) , meaning it allows external routes as NSSA external LSAs .
* Analysis of Each Answer Option:
A). " The routing table of R6 contains the route ::/0. " # FALSE
* R6 only participates in IS-IS (Level-1) and does not receive a default route (::/0) from Level-
2 routers.
* Since R6 is in IS-IS Level-1 and does not have a connection to a Level-2 router that provides a default route, it will not have a ::/0 route in its routing table .
Reference: HCIP-Datacom-Advanced Routing & Switching Technology, IS-IS IPv6 Routing Principles.
B). " The routing table of R5 contains the route 2000::6/128. " # TRUE
R6 advertises 2000::6/128 via IS-IS to R3 and R2 .
R3 imports the IS-IS routes into OSPFv3 Area 0 .
Since R5 is in Area 2 (NSSA) and Area 2 can accept external routes (as NSSA external LSAs), R5 will learn
2000::6/128 from R3.
Reference: HCIP-Datacom-Advanced Routing & Switching Technology, OSPF NSSA Route Handling.
C). " The routing table of R4 contains the route 2000::6/128. " # TRUE
R4 is in Area 1 (Stub Area).
While Area 1 does not accept external routes, R4 still learns inter-area routes from Area 0 via R3 .
Since R3 redistributes 2000::6/128 into OSPFv3 Area 0, and R4 learns it from R3, R4 will have 2000::6
/128 in its routing table .
Reference: HCIP-Datacom-Advanced Routing & Switching Technology, OSPF Inter-Area Route Handling.
D). " The routing table of R1 contains the route 2000::6/128. " # TRUE
R1 is connected to R3, which is in Area 0.
Since R3 has imported IS-IS routes into OSPFv3 , R1 will learn 2000::6/128 through OSPF Area 0 as an inter-area route .
Reference: HCIP-Datacom-Advanced Routing & Switching Technology, OSPF Route Redistribution and Inter-Area Routing.
NEW QUESTION # 35
In the IS-IS network shown in the figure, R1 introduces the default route through the "default- route-advertise always level-1" command. Which of the following descriptions are correct?
(Multiple choice)
Answer: A,B
NEW QUESTION # 36
On the OSPF network shown in the figure, areas 1, 2, and 3 are common areas. The IP address of Loopback0 on R5 is 10.0.5.5/32, and OSPF is enabled on the interface using the network command.
ACL 2000 (with the matching rule shown in the figure) is configured on all routers. If the command filter
2000 import is run in area 0 (where R1, R2, and R3 reside), which of the following routers do not have the route 10.0.5.5/32 in their routing tables?
Answer: A,B,D
Explanation:
Comprehensive and Detailed In-Depth Explanation:
Understanding the OSPF Network Structure in the Question:
* OSPF Areas & Routers:
* Area 3: Contains R5 (which has loopback 10.0.5.5/32).
* Area 1: Contains R6.
* Area 2: Contains R4.
* Area 0 (Backbone Area): Contains R1, R2, and R3 (which interconnect the other areas).
* ACL 2000 Filtering Rule:
* The ACL rule 2000 explicitly denies 10.0.5.5/32 from being imported.
* The filter 2000 import command applies this filter to Area 0, preventing routes from Area 3 (including R5 ' s loopback) from being learned by Area 0 routers (R1, R2, and R3).
Route Distribution Analysis:
* R5 (Area 3):
* R5 has 10.0.5.5/32 configured on its Loopback0.
* Since OSPF is enabled, R5 advertises the route to R6 in Area 1.
* R6 (Area 1) # R2 (Area 0, Backbone Router):
* Without filtering, R6 would normally propagate 10.0.5.5/32 to R2 (since R2 is a backbone router in Area 0).
* However, since ACL 2000 is applied in Area 0, R2 blocks this route from being imported.
* Therefore, R2 does not learn 10.0.5.5/32.
* R2 # R1 and R3 (Both in Area 0):
* R2 would typically share any learned routes with R1 and R3 in Area 0.
* But since R2 itself does not have 10.0.5.5/32, neither R1 nor R3 can receive it.
* Thus, R1 and R3 also do not have 10.0.5.5/32 in their routing tables.
* R4 (Area 2) is Unaffected:
* Since R4 is in Area 2, it is not directly impacted by the filter applied in Area 0.
* It can still receive the route via another path if redistribution is configured properly.
Final Conclusion:
* R1, R2, and R3 do not have the 10.0.5.5/32 route due to the filter 2000 import command applied in Area 0.
* R4 may still have the route since it is not affected by the filtering in Area 0.
Thus, the correct answer is:
# R1, R3, R2 do not have the route 10.0.5.5/32 in their routing tables.
