2 Advanced GSLB configuration for IPv6

For example, you could add the zone gslb.com, add the host www within the gslb.com zone, and assign a weight of 50 to the IP address 2001:DB8::56 by entering commands such as the following:

SLB-ServerIronADX(config-gslb-policy)# weighted-ip SLB-ServerIronADX(config-gslb-policy)# gslb dns zone gslb.com SLB-ServerIronADX(config-gslb-dns-gslb.com)# host www http SLB-ServerIronADX(config-gslb-dns-gslb.com)# host www ip-weight 2001:db8::56 50

Syntax: [no] weighted-ip

Syntax: [no] gslb dns zone <name>

For <zone-name>, enter up to 32 characters.

Syntax: [no] host-info<host-name> <host-application> <tcp/udp-portnum>

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.gslb.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 ServerIron 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-infoip-weightcommand and its operands to identify the host, the IPv6 address, and the weight.

Enter a command such as the following:

ServerIronADX(config)# gslb dns zone brocade.com ServerIronADX(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.
