NEW QUESTION # 14
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: B
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 # 18
In the figure, the company wants to ensure secure communication between the headquarters and branch , and isolate the R & D areas from non-R & D areas , without changing the current network deployment.
To meet this requirement, an administrator deploys BGP/MPLS IP VPN on the network .
Which of the following statements are true?
Answer: A,C
Explanation:
Comprehensive and Detailed In-Depth Explanation:
To verify the correct answers, let ' s analyze how BGP/MPLS IP VPN is used for secure communication and isolation in an enterprise network.
1. Understanding BGP/MPLS IP VPN Concepts
MPLS VPN (Multiprotocol Label Switching Virtual Private Network) is used to:
* Allow communication between specific sites by using Route Targets (RTs) .
* Ensure isolation of specific areas (e.g., R & D vs. non-R & D) by controlling RT import/export policies .
* Utilize Route Distinguisher (RD) to make overlapping IP addresses unique within the VPN.
2. Analyzing the Answer Choices
# A. " To enable communication between the headquarters and branch R & D areas, both the ERT and IRT of VPN1 and VPN2 can be set to 100:100. " # TRUE
* Explanation:
* ERT (Export Route Target) and IRT (Import Route Target) define which VPNs share routing information .
* If VPN1 (HQ R & D) and VPN2 (Branch R & D) use the same RT (100:100), they will exchange routes, enabling communication.
* Correct configuration:
VPN1: ERT 100:100, IRT 100:100
VPN2: ERT 100:100, IRT 100:100
* # This is correct and enables communication between HQ and branch R & D areas.
# B. " To implement communication between the headquarters and branch R & D areas, the RDs of VPN1 and VPN2 need to be set to the same value. " # FALSE
* Explanation:
* RD (Route Distinguisher) is only used to make overlapping IP addresses unique within the MPLS VPN.
* RD does NOT control route exchange between VPNs (RTs control route exchange).
* VPN1 and VPN2 can have different RDs but still communicate if they share the same RT (100:100).
* # RDs do NOT need to be the same for VPNs to communicate.
* # This statement is false.
# C. " R & D areas and non-R & D areas have overlapping address spaces. Therefore, services in the two areas cannot be isolated. " # FALSE
* Explanation:
* Overlapping address spaces are common in MPLS VPNs and can be isolated using unique Route Targets (RTs).
* As long as VPNs have different RTs, their traffic remains isolated.
* For example:
VPN1 (R & D): RT 100:100
VPN3 (non-R & D): RT 200:200
* Even with overlapping IPs, R & D and non-R & D areas are completely isolated.
* # This statement is false.
# D. " To isolate R & D areas from non-R & D areas at the headquarters, the RTs of VPN1 can all be set to 100:100 and the RTs of VPN3 can all be set to 200:200. " # TRUE
* Explanation:
* Setting different RTs for R & D (100:100) and non-R & D (200:200) ensures complete isolation .
* Correct configuration:
VPN1 (R & D): RT 100:100
VPN3 (non-R & D): RT 200:200
* Since VPN1 and VPN3 do NOT share the same RTs, their routes remain separate.
* # This ensures isolation between R & D and non-R & D areas.
