Brocade Communications Systems 6650 manual Defining an IPv6 DNS entry

IPv6 management on Brocade ICX 6650 devices (IPv6 host support) 5

The CLI displays trace route information for each hop as soon as the information is received. Traceroute requests display all responses to a minimum TTL of 1 second and a maximum TTL of 30 seconds. In addition, if there are multiple equal-cost routes to the destination, the Brocade device displays up to three responses.

For example, to trace the path from the Brocade device to a host with an IPv6 address of 2001:DB8:349e:a384::34, enter the following command:

Brocade#traceroute ipv6 2001:DB8:349e:a384::34

Syntax: traceroute ipv6 <ipv6-address>

The <ipv6-address> parameter specifies the address of a host. You must specify this address in hexadecimal using 16-bit values between colons as documented in RFC 2373.

Configuring name-to-IPv6 address resolution using

IPv6 DNS resolver

The Domain Name Server (DNS) resolver feature lets you use a host name to perform Telnet and ping commands. You can also define a DNS domain on a Brocade device and thereby recognize all hosts within that domain. After you define a domain name, the Brocade device automatically appends the appropriate domain to the host and forwards it to the domain name server.

For example, if the domain “example.com” is defined on a Brocade device, and you want to initiate a ping to host “EXA01” on that domain, you need to reference only the host name in the command instead of the host name and its domain name. For example, you could enter either of the following commands to initiate the ping.

Brocade#ping ipv6 exa01

Brocade#ping ipv6 exa01.example.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.

AAAADNS 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 establish an IPv6 DNS entry for the device, enter the following command.

Brocade(config)#ipv6 dns domain-name companyA.com

Syntax: [no] ipv6 dns domain-name <domain name>

To define an IPv6 DNS server address, enter the following command.

Brocade(config)#ipv6 dns server-address 2001:DB8::1

Syntax: [no] ipv6 dns server-address<ipv6-addr> [<ipv6-addr>][<ipv6-addr>][<ipv6-addr>]
