Advanced GSLB configuration for IPv6
2
The host-name variable specifies the host name. You do not need to enter the entire fully qualified
host name. Enter only the host portion of the name. For example, if the fully qualified host name is
www.example1.com, do no enter the entire name. Enter only "www". The rest of the name is already
specified by the gslb dns zone command.
The host-application parameter specifies the host application for which you want to create an IP
list. Specify one of the following:
•
ftp: the well-known name for port 21. (Ports 20 and 21 both are FTP ports but on the Brocade
Virtual ADX, the name ftp corresponds to port 21.)
•
tftp: the well-known name for port 69
•
http: the well-known name for port 80
•
imap4: the well-known name for port 143
•
ldap: the well-known name for port 389
•
nntp: the well-known name for port 119
•
pop3: the well-known name for port 110
•
smtp: the well-known name for port 25
•
telnet: the well-known name for port 23
Specifying the weight of IP addresses in the IP list
To specify the weight given to an IPv6 address, use the host-info ip-weight command and its
operands to identify the host, the IPv6 address, and the weight.
Enter a command such as the following:
Virtual ADX(config)#gslb dns zone brocade.com
Virtual ADX(config-gslb-dns-brocade.com)#host-info www ip-weight 2001:db8::56 10
The command in the example specifies a weight of 10 for the IPv6 address.
Syntax: [no] host-info host-name ip-weight {ipv6-address weight}
The host-name variable specifies the host name under the zone. Again, you do not need to enter
the entire fully qualified host name. Enter only the host portion of the name.
The ipv6-address variable specifies the proxy IPv6 address(es) to which you are assigning a weight.
The weight is a value from 0 to 100. The default value is 0.
The command results in an “IP-address not found for host-name” error if the IPv6 address
specified for the ip-weight parameter was not used as an argument when you defined the IP list. For
information about specifying IP lists, see
“Specifying DNS override IP lists”
NOTE
If no IP list is defined for the host, the IP weight for the host IPs are removed from the GSLB DNS
zone configuration whenever the GSLB Brocade Virtual ADX reloads.
Use the show gslb dns command to view information about the distribution of traffic after the
configuration of weighted IP metrics. For information, refer to
