Whate exactly are those "uplinks" on the RSP 720s used for? Its a bit strange.
Can they be used as regular data ports, as in any other SUP module, or do they have a specific and limited use? Is it just for management?
Do you HAVE to configure them with IP addresses at all? What is the benefit or drawback of using or not using them? Why do they exist?
If you do decide to configure IP address on both RSPs, can you use the SAME ip address?
I tried looking up this specific informaton on Ciscos website,and I did find plenty on the RSP modules, but nothing about te "uplink" ports and what they are used for.
