Hi, have anyone tested what does router do with layer 2 header of one packet arrived on one subinterface destined to another subinterface. I wonder if it can change source field with its corresponding subinterface mac address or with its physical interface?
And second question:
int g0/0.1
encapsulation dot1q 2 native
ip add y.y.y.y /24
int g0/0.2
encapsulation dot1q 4
ip add x.x.x.x/24
when router receives packet from switch tagged with vlan 4, destined to vlan 2 what router must do with tagging while sending packet via g0/0.1. ?
As i understand (correct if i'm not right) router must send packet without tag information.
