To ping an IPv6 address, you use the ping ipv6
command followed by the IPv6 address you wish to test. This will verify if the IPv6 address is reachable and display the corresponding statistics.
Understanding the ping ipv6
Command
The ping ipv6
command, as described in the reference, allows you to test the reachability of an IPv6 address. It also offers a range of options to customize the ping process:
Option | Description |
---|---|
-a source-ipv6 |
Specifies the source IPv6 address for the ping. |
-c count |
Sets the number of ping packets to send. |
-m interval |
Determines the interval between sending ping packets in milliseconds. |
-s packet-size |
Configures the size of the ping packet in bytes. |
-t timeout |
Sets the timeout for a response, in seconds. |
-tos tos |
Defines the Type of Service (ToS) field in the IP header. |
-vpn-instance vpn-instance-name |
Specifies the VPN instance name. |
host |
The IPv6 address of the target to ping. |
-i interface-type interface-number |
Specifies the interface through which the ping packets are sent. |
Practical Examples
Here are some examples of using the ping ipv6
command:
- Basic Ping: To ping the IPv6 address
2001:0db8:85a3:0000:0000:8a2e:0370:7334
, you would use:ping ipv6 2001:0db8:85a3:0000:0000:8a2e:0370:7334
- Ping with a specific number of packets: To send 5 ping packets, you would use:
ping ipv6 -c 5 2001:0db8:85a3:0000:0000:8a2e:0370:7334
- Ping with a specific source IPv6 address: To use
2001:0db8::1
as the source address, you would use:ping ipv6 -a 2001:0db8::1 2001:0db8:85a3:0000:0000:8a2e:0370:7334
- Ping through a specific interface: If you need to ping through interface
GigabitEthernet 1/0/1
, you would use:ping ipv6 2001:0db8:85a3:0000:0000:8a2e:0370:7334 -i GigabitEthernet 1/0/1
Interpreting Results
The output of the ping ipv6
command will show you whether the target IPv6 address is reachable and, if so, the time it takes for packets to travel to and from the destination. This information is vital for diagnosing network connectivity issues.
