Cisco WAN :: 6506 - How To Configure RTR In Network

We want to configure RTR in our network ,having a Cisco 6506 core Switch & 50 Cisco 2960 Switches. As per the ios on the 6506 the rtr command is supported not the ip sla , so we want to configure it on it.
 
The RTR configuration on the Source device (Cisco 6506 Sw) can be done through the below commands :

1)          enable
2)          configure terminal
3)           rtr   <Entry number>
4)          type echo protocol ipIcmpEcho <Hostname or A.B.C.D  IP address or hostname>  source-ipaddr < IP address >
5)          frequency seconds
6)          exit
7)          rtr schedule entry-number [life {forever | seconds}] [start-time {hh:mm[:ss] [month day | day month] | pending | now | afterhh:mm:ss] [ageout seconds] [recurring]
8)          exit
 
RTR configuration on the target devices (Cisco 2950  SW )will be :

1)          enable
2)          configure terminal
3)          rtr responder
4)          exit
 
The query here is that :

1) Is this configuration will work ?

2) And for every Cisco 2950 Switch , i have to create  seprate rtr entry on Cisco 6506 Sw for example for 50 target device i have to create 50 entries on source device 6506?
