If you disect routed-port it is actually a
SVI with vlan number 1006-4009 (reserved VLAN).
So from layer 3 perspective they are same.
From layer 2 perspective - there are some differences like mac-address etc.
(routed port inherits ports mac-address)
I think routed ports gives you an option to convert a 50 port switch to a 50
port router with physical interfaces (SVI are virtual interfaces)
But i agree with you - i haven't seen any difference either in L3
perspective
thanks
