Which of the following advantages is/are inter-VLAN route interworking in one-arm routing mode?
One-arm routing, also known as router-on-a-stick, reduces the number of physical links required for inter-VLAN routing by utilizing a single physical or logical connection between the router and the switch. This single connection carries multiple VLANs' traffic, thus eliminating the need for multiple links, which is a significant advantage in network configuration.
one-arm routing mode reduces number of links
One of the advantages of one-arm routing mode is that it reduces the number of links required for inter-VLAN routing, as only one link is needed between the router or Layer 3 switch and the switch
Answer is A. The number of inter-links reduces via one-arm routing mode.
The answer is A reduced used link
D. Reduced the number of entries in the routing table In inter-VLAN route interworking in one-arm routing mode, the routing between VLANs is performed by a single router interface (one-arm routing), and this can lead to a reduction in the number of entries in the routing table. The router interface is connected to a switch, and traffic between VLANs is routed through this interface. Options A, B, and C are not directly associated with the advantages of inter-VLAN route interworking in one-arm routing mode. The reduction in the number of entries in the routing table is a specific advantage of this routing mode, as the router can route traffic between VLANs without needing separate physical interfaces for each VLA
How it will reduce the number of routes in the routing table? this is not true at all. if you have 3 routes forwarded to the same links you will find the 3 routes in the routing table with the same interface as next-hop. it will never reduce the number of entries in the routing table. The correct answer is A
The answer is A Explanation : A router on a stick, also known as a one-armed router, is a router that has a single physical or logical connection to a network. It is a method of inter-VLAN routing where one router is connected to a switch via a single cable.
