I am testing the InterVLAN routing using a router in stick mode doing VLAN routing between VLAN 2 & VLAN 3. These two VLANs are configured in a Layer 2 switch connecting this ROUTER-1 and Hosts
say HOST-2 and HOST-3
ROUTER-1 fa 0/0 is configured with subinterface fa0/0.3 & fa 0/0.2 and the configuration is
interface fa 0/0.2
ip add 192.168.2.1 255.255.255.0
encapsulation dot1Q 2
interface fa 0/0.3
ip add 192.168.3.1 255.255.255.0
encapsulation dot1Q 3
It is working perfectly in this configuration routing between VLAN 2 & VLAN 3
If I add keyword native to either "encapsulation dot1Q 2" or "encapsulation dot1Q 2", I am not able to reach from VLAN 2 to VLAN 3.
I learned that "The native VLAN is used for untagged traffic when the port is in 802.1Q trunking mode"
How it is conflicting in our scenario. I expected that whenever the packet comes without VLAN tag only those packets will be tagged with either VLAN 2 or VLAN 3.
Can you please take your valuable time in explaning this?
you have used a different account for this reason you cannot flag as solved the answer.
but don't worry about this.
>> So, I will presume that native keyword can be used only in one of the sub-interface and not in all.
Hope to help
