[j-nsp] vlan-id 0

[Bit Gossip]

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. A value of 0 means that the frame doesn't belong to any
VLAN; in this case the 802.1Q tag specifies only a priority and is
referred to as a priority tag"

How would I match this Juniper config:

show configuration interfaces ge-0/0/0 
vlan-tagging;
unit 0 {
    vlan-id 0;
    family inet {
        address 1.1.1.1/30;
    }
}

on a cisco device on the other end of the cable where vlan starts from
1?

r2(config-subif)#encapsulation dot1Q ?
  <1-4094>  IEEE 802.1Q VLAN ID required

Thanks,
bit
