No
Routed-port = SVI port of avaliable extended VLAN (1006-4096)
switch-2#sh run inter f0/11
Building configuration...
Current configuration : 64 bytes
!
interface FastEthernet0/11
no switchport
no ip address
end
switch-2#sh vlan internal usage
VLAN Usage
---- --------------------
1026 FastEthernet0/11
switch-2#
in this case
routed-port f0/11 = SVI of 1026
f0/11 = switchport of 1026
So f0/11 is associated with VLAN 1026, but is also SVI of itself
thanks
