NEW QUESTION # 129
A certain park deployed both IPv4 and IPv6 networks for service testing, and IS-IS was run to achieve network interconnection. IS-IS routing protocol has good scalability and is widely used in existing networks.
Regarding IS-IS scalability, which of the following statements are correct? (Multiple choice)

  • A. NLPID is a new TLV of IS-IS to support IPv6
  • B. IS-IS needs to add TLV to carry Pv6 address information in order to support PV6
  • C. IS-IS uses TLV structure to construct messages, which makes IS-IS more flexible and expandable
  • D. For IS-IS, adding new features only needs to add a new TLV

Answer: B,C,D


NEW QUESTION # 130
On the enterprise network shown in the figure, R3 is connected to the NMS, and all devices on the network communicate with the NMS through a VPN.
During an inspection, it is found that R3 has redundant RTs (Route Targets).
Which of the following commands can be run on R3 to delete the redundant RTs without affecting the connectivity between all devices and the NMS?

Options:

  • A. undo vpn-target 2:3 export-extcommunity
  • B. undo vpn-target 1:3 export-extcommunity
  • C. undo vpn-target 3:1 import-extcommunity
  • D. undo vpn-target 1:3 import-extcommunity

Answer: A,B

Explanation:
Comprehensive and Detailed In-Depth Explanation:
1. Understanding VPN Route Targets (RTs) in MPLS VPNs
* Route Targets (RTs) define which VPN routes should be imported and exported among PE routers.
* Import-extcommunity: Specifies which VPN routes should be accepted into a VRF.
* Export-extcommunity: Specifies which VPN routes should be advertised from a VRF.
* Correctly configuring RTs ensures proper route exchange between VPN sites.
2. Analyzing the RTs in the Diagram
R3's Current Configuration:

vpn-target 3:1 export-extcommunity
vpn-target 3:2 export-extcommunity
vpn-target 1:3 export-extcommunity
vpn-target 1:3 import-extcommunity
vpn-target 3:1 import-extcommunity
vpn-target 3:2 import-extcommunity
R1's Configuration:

vpn-target 2:3 export-extcommunity
vpn-target 3:2 import-extcommunity
* R3 has redundant RTs because it both exports and imports unnecessary RTs.
* We need to remove only redundant RTs without affecting NMS connectivity.
3. Evaluating Each Answer Choice
A: "undo vpn-target 3:1 import-extcommunity" (# Incorrect)
* R1 exports RT 1:3, and R3 imports it as 3:1.
* Removing 3:1 import-extcommunity would block R3 from receiving routes from R1, disrupting connectivity to NMS.
* Thus, this option is incorrect.
B: "undo vpn-target 1:3 export-extcommunity" (# Correct)
* R3 exports RT 1:3, but there is no need for R3 to advertise routes with 1:3.
* R1 already exports 1:3, and R3 only needs to import it.
* Removing vpn-target 1:3 export-extcommunity does not affect connectivity but eliminates redundancy.
* # This is a correct choice.
C: "undo vpn-target 1:3 import-extcommunity" (# Incorrect)
* R3 needs to import 1:3 to receive routes from R1 (which is required for NMS communication).
* If removed, R3 will not receive necessary routes, breaking connectivity.
* Thus, this option is incorrect.
D: "undo vpn-target 2:3 export-extcommunity" (# Correct)
* R2 exports RT 2:3, but R3 does not need to receive it.
* This RT is redundant and can be removed without affecting connectivity.
* # This is a correct choice.
4. Evaluating the Answer Choices
Option
Correct?
Reasoning
A
# Incorrect
R3 must import 3:1 from R1 to maintain connectivity.
B
# Correct
Removing export-extcommunity 1:3 eliminates redundancy without affecting connectivity.
C
# Incorrect
Removing import-extcommunity 1:3 would block R3 from receiving necessary routes.
D
# Correct
Removing export-extcommunity 2:3 eliminates redundancy without affecting connectivity.
# Correct answer: B and D.
Final Conclusion:
* Route Targets (RTs) are used in MPLS VPNs to control route import/export policies.
* R3 has redundant RTs, and removing unnecessary exports (1:3 and 2:3) optimizes configuration.
* Correct commands to remove redundancy without affecting connectivity are:
* # undo vpn-target 1:3 export-extcommunity
* # undo vpn-target 2:3 export-extcommunity
* Thus, the correct answer is: B and D.
