Some attached devices may not accept 802.1q-tagged frames, and therefore can reside only in VLAN 0. Conversely, some devices may accept only tagged frames, requiring that even frames in VLAN 0 be tagged. So JUNOS is providing you the way to deal with such boxs.. :D
The range for valid VLAN IDs on Cisco kit is 1 to 4094 with VLAN 1 being the default VLAN. I suspect VLAN 1 might be what you are talking about when they refer to VLAN 0. However, to muddy the water, Cisco's documentation for the 3750 reveals that there IS a VLAN 0 - but only when you're using VOIP Regards, Masood Blog: http://weblogs.com.pk/jahil/ > Experts, > do you know what is the meaning of vlan-id 0? > According to: http://en.wikipedia.org/wiki/IEEE_802.1Q > "VLAN Identifier (VID): a 12-bit field specifying the VLAN to which the > frame belongs.
