Use the undo crp-policy command to remove the restrictions in C-RP address 
ranges and the ranges of served multicast groups.

By default, there are no restrictions on C-RP address ranges and the address 
ranges of served groups, namely all received C-RP messages are accepted.

# In the public instance, configure a C-RP address range and a range of served 
multicast groups so that only routers in the address range of 1.1.1.1/32 can be 
C-RPs and these C-RPs can serve only multicast groups in the address range of 
225.1.0.0/16.
