instead of the host name and its domain name. For example, you could enter either of the following
commands to initiate the ping.
device#ping ipv6 nyc01
device#ping ipv6 nyc01.newyork.com
Defining an IPv6 DNS entry
IPv6 defines new DNS record types to resolve queries for domain names to IPv6 addresses, as well as
IPv6 addresses to domain names. Brocade devices running IPv6 software support AAAA DNS records,
which are defined in RFC 1886.
AAAA DNS records are analogous to the A DNS records used with IPv4. They store a complete IPv6
address in each record. AAAA records have a type value of 28.
To define an IPv6 DNS server address, enter command such as the following:
device(config)#ipv6 dns server-address 2001:DB8::1
Syntax: [no] ipv6 dns server-address ipv6-addr [ ipv6-addr ] [ ipv6-addr ] [ ipv6-addr ]
The ipv6 dns server-address parameter sets IPv6 DNS server addresses.
As an example, in a configuration where ftp6.companynet.com is a server with an IPv6 protocol stack,
when a user pings ftp6.companynet.com, the Brocade device attempts to resolve the AAAA DNS
record. In addition, if the DNS server does not have an IPv6 address, as long as it is able to resolve
AAAA records, it can still respond to DNS queries.
Pinging an IPv6 address
NOTE
This section describes the IPv6ping command. For details about IPv4 ping , see "FastIron Ethernet
Switch Layer 3 Routing Configuration Guide".
The ping command allows you to verify the connectivity from a Brocade device to an IPv6 device by
performing an ICMP for IPv6 echo test.
For example, to ping a device with the IPv6 address of 2001:DB8:847f:a385:34dd::45 from the Brocade
device, enter the following command.
device#ping ipv6 2001:DB8:847f:a385:34dd::45
Syntax: ping ipv6 ipv6-address [ outgoing-interface [ port | venumber ]] [ source ipv6-address ] [
count number ] [ timeout milliseconds ] [ ttl number ] [ size bytes ] [ quiet ] [ numeric ] [ no-fragment ]
[ verify ] [ data 1-to-4-byte-hex ] [ brief ]
• The ipv6-address parameter specifies the address of the router. You must specify this address in
hexadecimal using 16-bit values between colons as documented in RFC 2373.
• The outgoing-interface keyword specifies a physical interface over which you can verify
connectivity. If you specify a physical interface, such as an Ethernet interface, you must also specify
the port number of the interface. If you specify a virtual interface, such as a VE, you must specify the
number associated with the VE.
• The source ipv6-address parameter specifies an IPv6 address to be used as the origin of the ping
packets.
• The count number parameter specifies how many ping packets the router sends. You can specify
from 1 - 4294967296. The default is 1.
