The output shows that:
• The destination is reachable.
• T h e ro u t e i s 1.1.1.1 < - > { 1.1.1. 2; 1.1.2.1 } < - > 1.1. 2. 2.

Field Descri
tion
Ping 1.1.2.2 (1.1.2.2): 56 data
bytes, press CTRL_C to break
Test whether the device with IP address 1.1.2.2 is reachable. There are
56 bytes in each ICMP echo request. Press Ctrl+C to abort the ping
operation.
56 bytes from 1.1.2.2: icmp_seq=0
ttl=254 time=4.685 ms
Received ICMP echo replies from the device whose IP address is
1.1.2.2. If no echo reply is received within the timeout period, no
information is displayed.
• bytes—Number of bytes in the ICMP echo reply.
• icmp_seq—Packet sequence, used to determine whether a segment
is lost, disordered or repeated.
• ttl—TTL value in the ICMP echo reply.
• time—Response time.
RR:
Routers through which the ICMP echo request passed. They are
displayed in inversed order, which means the router with a smaller
distance to the destination is displayed first.

ping ipv6
Use ping ipv6 to determine whether an IPv6 address is reachable, and display related statistics.
Syntax
ping ipv6 [ -a source-ipv6 | -c count | -i interface-type interface-number | -m interval | -q | -s
packet-size | -t timeout | -tc traffic-class| -v | -vpn-instance vpn-instance-name ] * host

Parameters
-a source-ipv6: Specifies an IPv6 address of the device as the source IP address of ICMP echo requests.
If this option is not specified, the source IPv6 address of ICMP echo requests is the IPv6 address of the
outbound interface. (The address selection rule is defined by RFC 3484.)
