29.1 Commands for DHCPv6 option37, 38
29.1.1 address range
Command:
address range <start-ip> <end-ip>
no address range <start-ip> <end-ip>
Function:
This command is used to set address range for a DHCPv6 class in DHCPv6 address pool
configuration mode, the no command is used to remove the address range. The prefix/plen form is
not supported.
Parameters:
start-ip, defines the start address of the address pool
end-ip, defines the end address of the address pool
Command Mode:
Admin Mode.
Usage Guide:
It is necessary to check the address range assigned to class in order to make sure that it doesn’t
exceed the address range of relevant address pool. A class is assigned a single address range and
the address range assigned to different class in the same address pool can overlap. If you do not
use this command to assign address range for a DHCPv6 class, then the range for it will be the
whole subnet of the address pool by default.
Example:
Associate a DHCPv6 class named CLASS1 to dhcpv6 pool 1 and assign the address range from
2001:da8:100:1::2 to 2001:da8:100:1::30 for CLASS1.
Switch(Config)#ipv6 dhcp pool 1
Switch(dhcp-1-config)#class CLASS1
Switch(dhcp-1-class-CLASS1-config)#address range 2001:da8:100:1::2 2001:da8:100:1::30
