Hi there,

I am wondering why I can see some VLANs configured on L3 interfaces in
the internal VLAN usage.
Wasn't it supposed to show up only internal VLANs allocated from the
range 1006-4094? 

For example:

7609#show vlan inter usage
 
VLAN Usage
---- --------------------
20    GigabitEthernet4/1.20
21    GigabitEthernet4/1.21     <<<<<<< new subinterface accounted as
internal vlan
1006 online diag vlan0   
1007 online diag vlan1   
1008 online diag vlan2   
1009 online diag vlan3   
1010 online diag vlan4   
1011 online diag vlan5   
1012 PM vlan process (trunk tagging)
1013 Control Plane Protection
1014 NDE 
1015 Container0
1016 L3 multicast partial shortcuts for VPN 0
1017 Egress internal vlan
1018 Multicast VPN 0 QOS vlan
1019 IPv6 Multicast Egress multicast
1020 GigabitEthernet4/2
1021 GigabitEthernet4/1

PS: Only tested in SRB train.

Thanks in advance.
