I have a catalyst 3750 switch with version c3750-advipservicesk9-mz.122-46.SE.bin installed. Now I would like to configure vrf-lite. I have made all the configuration for vrf and ospf. For the connection to the next router I configured a port as no switchport. Now I tried to configure a subinterface. I always got an error like
PM5(config)#inter gig 1/0/3.10
% Invalid input detected at '^' marker.
Is there anything wrong in my configuration or do I have a wrong image file on the switch?
thank you for your help
