Hello community, I have a query regarding packet transmission in the VLAN arena. First, let me give a picture of the configuration I have: Eth3 eth4 Eth3.2 eth4.2 I have assigned eth3.2 an IP of 51.1.2.2 and eth4.2 an IP of 51.1.20.2 A call is made from 51.1.2.2(i.e. eth3.2) to 51.1.20.2(i.e. eth4.2). The issue I have noted is that when monitoring a call via ethereal I see that the same RTP packet is being sent twice. However, one of the packet is has a VLAN Tag while the other one has no Tag but both of them go to the same address. -The question is why is this the case? i.e. why do we have same packet twice; one Tagged while the other Untagged? -Is it fair to assume that the Tagged packet goes to eth4.2 while the Untagged one goes to eth4 ? -If this is the case does it mean eth3.2 originates the same packet twice? Or it?s simply that the same packet is being sent twice but one by eth3(Untagged) and the other by eth3.2(Tagged) ? I wonder why this would be the case though. As always, Thank you in advance.
