R1#ping 2020::1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2020::1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 0/36/104 ms

!--- Router R1 is successfully able to ping !--- router R2's loopback address.

R1#ping 2001::2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2001::2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 12/40/116 ms
