NEW QUESTION # 17
VLAN aggregation is configured on a switched network. Sub-VLAN 2 and Sub-VLAN 3 are added to Super-VLAN 10 . To enable hosts in different sub-VLANs to communicate with each other , run the following command in the VLANIF 10 view corresponding to the Super-VLAN .
(Enter lowercase letters.)
Answer:
Explanation:
inter-sub-vlan-proxy enable
Explanation:
Understanding VLAN Aggregation (Super-VLAN and Sub-VLANs)
* VLAN aggregation allows multiple sub-VLANs to be grouped under a super-VLAN , reducing the number of VLANIF interfaces required for IP address configuration.
* Super-VLAN : A logical VLAN that does not forward Layer 2 traffic directly but is used for Layer 3 communication .
* Sub-VLANs : VLANs that exist within the Super-VLAN but cannot communicate with each other by default.
2# # Why is the " inter-sub-vlan-proxy enable " Command Needed?
* By default, hosts in different sub-VLANs under the same super-VLAN cannot communicate with each other because sub-VLANs do not exchange MAC address information.
* The inter-sub-vlan-proxy enable command allows Layer 3 communication between sub-VLANs under the same super-VLAN by acting as a proxy for ARP requests and replies .
* This enables inter-sub-VLAN communication while still reducing the number of VLANIF interfaces required.
3# # Command Syntax and Execution
* The correct command should be run under the VLANIF interface of the super-VLAN :
[Switch] interface vlanif 10
[Switch-Vlanif10] inter-sub-vlan-proxy enable

NEW QUESTION # 18
On the OSPF network shown in the figure, the cost values of links are marked. OSPF IP FRR is enabled on R1 , and the maximum load-balancing 8 command is configured in the OSPF process. If a service passes through the path R1 # R5 # R3 to reach 10.0.3.3/32 , which of the following is the backup outbound interface for the service?
Answer: A
Explanation:
Comprehensive and Detailed In-Depth Explanation:
Step 1: Identify the Primary Path
* The shortest OSPF cost to 10.0.3.3/32 from R1 is through R5 :
* R1 # R5 (Cost 10) # R3 (Cost 10) = Total Cost 20
* The primary outbound interface from R1 to R5 is GE0/0/1 .
Step 2: Identify the Backup Path (OSPF IP FRR & ECMP)
* OSPF IP Fast Reroute (FRR) provides a backup next-hop in case the primary link (R1 # R5) fails.
* A feasible backup path must have a cost equal to or close to the primary path , but it must avoid the same failure point.
Alternative Path Calculation:
* Path 1 (R1 # R2 # R3)
* R1 # R2 (Cost 10), R2 # R3 (Cost 10) # Total Cost = 20 #
* Uses interface GE0/0/2 on R1.
* Path 2 (R1 # R4 # R3)
* R1 # R4 (Cost 10), R4 # R3 (Cost 10) # Total Cost = 20 #
* Uses interface GE0/0/3 on R1.
Final Decision on the Backup Interface
* Since both paths R1 # R2 # R3 and R1 # R4 # R3 have equal costs, either can be used for backup.
* However, R1 # R2 # R3 shares a direct cost path with R5 , meaning it may not be preferred as a full FRR backup.
* The best backup outbound interface in this scenario is GE0/0/3 (R1 # R4 # R3) .
Final answer: # C (GE0/0/3)
