Based on the network diagram and routing table output in the exhibit, which of these statements is true?
A.
InterVLAN routing will not occur since no routing protocol has been configured.
B.
InterVLAN routing has been configured properly, and the workstations have connectivity to each other.
C.
Although interVLAN routing is not enabled, both workstations will have connectivity to each other.
D.
Although interVLAN routing is enabled, the workstations will not have connectivity to each other.
Explanation:
A Layer 2 network can also exist as a VLAN inside one or more switches. VLANs are essentially isolated from each other so that packets in one VLAN cannot cross into another VLAN.
To transport packets between VLANs, you must use a Layer 3 device. Traditionally, this has been a router’s function. The router must have a physical or logical connection to each VLAN so that it can forward packets between them. This is known as interVLAN routing. InterVLAN routing can be performed by an external router that connects to each of the VLANs on a switch. Separate physical connections can be used, or the router can access each of the VLANs through a single trunk link.
The Switch Port which is connected with Router should be trunk link, You need to configure like:
Switch(config)#interface fa 0/1
Switch(config-if)#switchport mode trunk
Switch(config-if)#switchport trunk encapsulation dot1q In Router you need to configure like:Router(config)#interface fa 0/0
Router(config-if)#description VLAN 1
Router(config-if)#ip address 192.168.10.1 255.255.255.0 Router(config)#interface fa 0/0.10
Router(config-subif)#description Management VLAN 10 Router(config-subif)#encapsulation dot1q 10
Router(config-subif)#ip address 192.168.91.1 255.255.255.0 Router(config)#interface fa 0/0.20
Router(config-subif)#description Engineering VLAN 20 Router(config-subif)#encapsulation dot1q 20
Router(config-subif)#ip address 192.168.20.1 255.255.255.0
